INERGEN TOTAL FLOODING SYSTEMS (300 BAR ENGINEERED SYSTEMS) 1.

INTRODUCTION

This manual has been prepared primarily for the use of Designers/Installers of INERGEN (300 bar) Fire Fighting Equipment. Its purpose is to provide general information on Inergen and its use in Fire Fighting systems and to give more detailed information covering the design, installation, testing and servicing of these systems.

Note: The manual covers the minimum requirements for the design of Total Flooding Systems. Local application and explosion su ppression systems are not covere d by the manual. Whilst marine and inerting systems are not specifically excluded these applications require additional considerations. If in doubt refer to the Extinguishing Technical Department. This manual has been prepared in the light of the best information available at the time of publication. It has been assumed that users of this manual have sufficient experience of Fixed Fire Fighting Systems to enable the correct interpretation to be made of the contents.

It must be recognised that correct system design, installation and maintenance are fundamental to the safe and effective use of any gaseous Fire Fighting System.

1.1

APPROVALS

The 300 bar INERGEN system is based on a number of components, some of which have been approved or listed by VDS. See Section 8 for VDS approved configurations.

1.1.1 TEMPERATURE RANGE The components are designed to operate in the temperature range -20ºC to 50ºC, or as otherwise stated in separate component listings.

1.2

GENERAL INFORMATION

INERGEN has been introduced as an alternative to Halon 1301, production of which ceased at the end of 1993, under the agreed adjustment made to the Montreal Protocol in November 1992. INERGEN is a mixture of three naturally occurring gases that do not support combustion, nor have an impact on the ozone layer. The three gases, Nitrogen, Argon and Carbon Dioxide are mixed in the following proportions: Nitrogen

52%

Argon CarbonDioxide

40% 8%

INERGEN storage containers are designed to hold INERGEN in gaseous form at a nominal pressure of 300 bar at 15°C. Handling and Installation of INERGEN equipment should only be carried out by persons experienced in dealing with this type of equipment.

DESCRIPTION OF INERGEN SYSTEMS

INERGEN systems are designed to extinguish fires involving flammable liquids, gases and class A hazards, especially electrical equipment. The systems are designed to be total flooding and consist of a fixed supply of INERGEN connected to a piping system with nozzles to direct the agent into an enclosed hazard. INERGEN extinguishes fires by lowering the oxygen content below the level that supports combustion. In simple terms if the oxygen content of the atmosphere is reduced to a level below 15%, most ordinary combustibles will not burn. As an example an INERGEN system will reduce the oxygen content from 20.9% to approximately 12.5% whilst increasing the carbon dioxide content from 0.03% to around 3%. The increase in carbon dioxide content increases an individual’s respiration rate and the body’s ability to absorb oxygen thus allowing the body to compensate for the lower oxygen content. Since INERGEN is stored as a gas, it discharges as an invisible gas, allowing people to safely exit a protected space without obscured vision. INERGEN systems are particularly valuable in extinguishing fires in enclosures containing hazards or equipment where a clean, electrically non-conductive medium is essential or where the cleaning up of foam, water or powder would be problematic.

PROPERTIES OF INERGEN

Under normal conditions INERGEN is an odourless colourless gas with a density similar to that of air. INERGEN does not decompose when subjected to heat from a fire so avoiding hazardous breakdown products, but it must be recognised that in a fire condition, decomposition products from the fire itself especially carbon monoxide, smoke and heat will create a hazard in the protected enclosure and the reduced oxygen level occurring in a fire situation may lower the resultant level below that calculated from the agent discharge alone. The following specification applies to INERGEN. Pressure

SAFETY OF INERGEN

1.5.1

GENERAL

INERGEN simultaneously reduces the oxygen concentration in an enclosure and increases the carbon dioxide concentration. Proper and safe INERGEN design requires that the design concentration falls within a design window that limits the upper and lower concentrations of oxygen and carbon dioxide. (as shown table 1) INERGEN has been accepted for use in occupied spaces when the design concentration falls within this window. If the INERGEN design concentration must be outside the design window, special safety devices based on national requirements have to be used.

16/12/05 CN

NOISE

Discharge of an INERGEN system can cause noise loud enough to be startling but ordinarily insufficient to cause traumatic injury.

1.5.1.3

TURBULENCE

High velocity discharge from nozzles may be sufficient to dislodge substantial objects directly in the path of the discharge. General in the be enclo sure may be suffi cient to them movebeing ligh t objects, unse curedthe paper etc. Ceiling tiles in the vicinity of theturbulence nozzles should clipped in place to prevent dislodged during discharge.

1.5.1.4

VISIBILITY

Under normal conditions INERGEN will not reduce visibility in the protected enclosure. However in a fire situation especially where large amounts of smoke are produced it is likely that the INERGEN discharge will produce some displacement of that smoke around the enclosure and this could reduce visibility in some circumstances.

1.5.1.5

EXITS

Adequat e means of escape from the protect ed area should be provide d. Doors should open outwa rds and be self closing. They should be arranged to open easily from inside and any that need to be secured must be fitted with escape overrides.

1.5.1.6

POST DISCHARGE VENTILATION

In order to allow for the ventilation of INERGEN and/or the post fire atmosphere, a normally closed means of ventilation with extract arrangemen ts will be required as with any gaseous extinguishing system. Any mechanical ventilation provided should not form part of the normal ventilation system. Controls for the ventilation system should be outside the protected enclosure and should be key operated. In some circumstances the normally closed means of ventilation may be provided by doors and windows. National standards or local fire brigade rules need to be taken into account and may differ from the information given above.

Oth er inform ation Further Information

When used in fire extinguishing systems, the quantities of INERGEN® are mostly designed so that oxygen concentrations of between 15 % by volume and 10 % by volume, and CO2 concentrations of between 2 % by volume and 5 % by volume, are present in the flooded room. No hazards for healthy people are known if they are present in this atmosphere for a short period. However, the combustion products generated during a fire may be highly toxic, so people leave any room that has been flooded with INERGEN® This information reproduces the status of knowledge of the party putting the product into commercial circulation. The information is not a contractual assurance of the product's quality characteristics, nor of the delivery specification all designs and specifications subject to change without notice

Information contained in this manual has been based generally on the ISO 14520 Standard on Clean Agent Fire Extinguishing Systems. The manual has been prepared to give an understanding in the application of INERGEN systems. Systems are suitable only for the total flooding of hazard enclosures.

2.2

DETERMINATION OF IN ERGEN QUANTITY

Prior to commencing with the design of any INERGEN system, the designer should have, as a minimum the following details: •

Enclosure dimensions

•

Specific details of the hazard

•

The minimum and maximum temperatures of the hazard enclosure

•

Height of the enclosure above (or below) sea level

•

Confirmation that the containment is adequate

•

Details of the ventilation system

•

Intended occupancy of the e nclosure

•

Storage location, should preferably be loading outside the protected must not be exposedcontainer to weather or other(this potential hazards. Floor should also beenclosure), taken into but consideration.

•

Details of National laws or requirements that need to be taken into account, for example TRG 280, which is applicable in Germany

The following notes provide additional information to assist the designer in providing the correct system for the hazard. INERGEN is suitable for the protection of hazards involving Class A, B & C materials. Providing a Class A fire is detected quickly, the INERGEN is discharged promptly and the concentration is maintained for an adequate period of time to allow embers to cool, then surface fire and the embers associated with the burning of solid materials are quickly extinguished. INERGEN is suitable for use on fires involving live electrical equipment but is not effective on, and should not be used to fight fires involving: •

Chemicals containing their own supply of oxygen, such as cellulose nitrate.

•

Mixtures containing oxidising agents such as sodium chlorate or sodium nitrate.

•

Chemicals capable of undergoing autothermal decomposition such as some organic peroxides.

• •

Reactive metals. Solid materials in which fires quickly become deep seated.

Class B & C fires are quickly extinguished by INERGEN at the appropriate concentrations, but in the case of Class C fires the risk of explosion should be carefully considered and where possible the flammable gas flow should be isolated before or as soon as possible after extinguishment.

Determine the gross room volume. Only permanent impermeable building structures within the area may be deducted from the gross volume. 1)

Establish the minimum anticipated temperature of the protected enclosure. This should be used as the design temperature when determining the agent quantity.

2)

Determine the minimum design concentration for the hazard involved. As INERGEN is released into an enclosure it displaces air and some INERGEN. Therefore more INERGEN is injected into an enclosure than remains when the discharge is completed. The proportion of air that has been replaced by INERGEN when the discharge is complete is called the design concentration.

The ratio of the volume of an enclosure to the volume of INERGEN injected into it is called the flooding factor. The relationship between the design concentration and the flooding factor may be summarised by the following equations. Design Concentration Flooding Factor

= 100 - 100 / e ff = ln (100 / (100 - dc))

The minimum design concentration as specified by ISO14520 is 36.5% however Tyco Safety Products would recommend the use of a minimum design concentration for the protection of electrical hazards of 40% - flooding factor 0.51 @ 20°C (cu.m INERGEN / cu.m protected space). Class B and C hazards will require separate consideration. A list of substances and the minimum design concentration applicable are indicated in Table 4. These values taken from ISO 14520 are based on the ‘extinguishing value’ plus 30% and then rounded up to the next nearest full number. If any doubt exists refer to the Extinguishing Technical Department. If the system is being designed in accordance with the VdS standard then the VdS requirement 2380 will have to be followed.

3)

Multiply the gross volume by the appropriate flooding factor from table 5 or determine the agent quantity required by using the following formula. Agent Quantity =V x (ln (100 / (100 - dc)) x ((0.70818 / (0.65799 + (0.00239 x t)))

Where,

dc = Design Concentration,

V = Enclosure Volume (cu.m),

t

= Enclosure Temperature.

Note: Adjust the agent quantity if the system is to be installed at altitudes that vary from sea level by more than 11%. The multiplying factor is shown in Table 6.

4)

Determine the quantity of INERGEN containers required by dividing the INERGEN quantity required by the capacity of each INEGEN container as shown in Table 3.

16/12/05 CN

The ‘Halon Alternatives Group’ report, ‘A review of the toxic and asphyxiating hazards of clean agent replacements for Halon 1301’, advises that INERGEN systems may be used in the fully automatic mode in occupied areas where the oxygen level does not reduce below 12% (flooding factor 0.56). In the event that the oxygen level is between 10% and 12% (flooding factor 0.74 - 0.56), the system may be on automatic providing the enclosure can be evacuated in less than 2 minutes. If the oxygen level falls below 10% (flooding factor greater than 0.74), the system must not be used in the automatic mode whilst the enclosure is occupied. In order to determine or confirm the theorectical oxygen concentration or confirm which of the above conditions apply, the following steps should be taken. 1)

Calculate the exact volume of INERGEN to be discharged into the protected enclosure by multiplying the number of containers to be provided by the volume of INERGEN contained in each (refer to Table 3).

2)

Divide the actual volume of INERGEN being provided by the net hazard volume to determine the actual flooding factor

3) 4)

Correct the flooding factor calculated above for temperature by dividing it by:0.70818 / (0.6598 + (0.002416 x t)) where, t = maximum enclosure temperature Relate the actual flooding factor to the conditions of use outlined above.

Note: See also Section 1.5.1.1. 2.2.2

DISCHARGE TIME TO ACHIEVE MIN. DESIGN CONCENTRATION

The ‘minimum’ design concentration is defined as the quantity of INERGEN required to achieve a concentration not less than the extinguishing value, plus a 30% safety factor, even if the actual design concentration for the hazard enclosure is greater than the ‘minimum’ value. For example, if the hazard consists of combustible materials that are extinguished at 28.1% to give a ‘minimum’ design concentration of 36.5% (say 37%) but the actual design is based on 40% design concentration, then the requirement is for 95% of the ‘minimum’ value (0.95 x 37%) ie, 35.2% concentration to be discharged within 1 minute. Expressed as an oxygen level the following calculation will apply:

100% - 35.2% = 64.8% of start level.

Therefore (assuming initial oxygen level of 21%) - 64.8% of 21% = residual oxygen level of 13.7%.

2.2.3

EXTENDED D ISCHARGE

Should the nature of the hazard determine that an extended discharge of INERGEN is required the system must be so configured that the requirement for 95% of the ‘minimum’ design concentration for the hazard enclosure is achieved within 1 minute. Any extended discharge should be designed to add INERGEN at such a rate as to compensate for losses. The duration of the extended discharge may be determined according to the nature of the hazard and the required hold time. All extended discharge systems should be referred to the Tyco Safety Products Technical Department.

2.2.4

CONNECTED RESERVES

Connected reserves can be accommodated in the system. The means to achieve this will normally be by means of a duplicate bank of INERGEN containers connected into a common manifold. All parts of the storage system will be duplicated but the pipework system from the container storage area and the discharge nozzles will normally be common.

2.2.5

STOP VALVES AN D DISTRIBUTION VALVE SYSTEM

Stop valves and distribution valves can be accommodated in the system. Both types of arrangement will create closed sections of pipework and may require pressure relieving devices (pressure relief valves) to satisfy national standards. The methodology by which to achieve the many configurations possible, in systems using distribution valves, will require the use of non-return valves, pilot line bleed valves, and may require the use of non-return valves, strategically positioned in the pneumatic pilot system. An example of a typical layout is shown in Fig. 5. The safe use of INERGEN should always comply with recognised national standards.

MAIN AND RESERVE SYSTEM - FUNCTIONAL DESCRIPTION

Below is a functional description of the system as shown in Fig 1. If fire breaks out it is detected in the early stages by the automatic detectors (smoke detectors, heat detectors etc.) (102) positioned in the extinguishing area and is signalled to the detection and control panel (101). Alternatively, a manual release push button (103) is also provided: this is positioned in the extinguishing area and can be operated manually be the staff.

Within the electical detection and control panel (101) the signal from either the automatic detectors (102), or the manual release (103), is processed internally, and initialy the following functions are carried out.

•

The accoustic alarm devices (104) are switched on in the extinguishing area (two independant alarm devices)

•

Visual indicators and alarms, if present, are switched on.

•

An adjustable delay period of between 10 and 60 seconds starts, enabling the staff the leave the extinguishing area. This delay can be achieved in one of two ways, either: a)

electonically, by the module in the fire detection and control panel (101), or

b)

via a stepper motor (106) and controller (101.1) with pulse technology.

•

The air conditioning / ventilation system is switched off, together with any operating equipment which may be present such a power supply (107).

•

A signal is given to close doors or other operational enclosures (107)

•

An alarm signal is sent to a permantly occupied location if one has been identified.

•

Other secondary signals are possible on a project specific basis.

After the delay period has elapsed, the actiation signal is given to the components of the extinguishing system: a)

signal to the electric actuator (108) on the pilot cylinder (201), or

b)

the stepper motor (106), as part of the pulse technology, has run out and manualy opens the cylinder valve (202) on the pilot cylinder (201).

When this happens, a release membrane is destroyed, causing gas from the pilot cylinder to move the valve piston downwards, which in turn opens the pilot cylinder valve (202), which can no longer be closed. The pilot cylinder gas, INERGEN 200 bar, flows via the pilot pipe (203) to the connected container valves (302) of the extinguishing agent containers (301)

The container valves (302) of the container battery that is to be opened are opened pneumatically.

The bar, extinguishing agent,the INERGEN 300 bar, flows via the pressure reduction with it’s pressure reduced to 200 it flows through respective container connection hose (304) and the unit non (303): return valve (305) into the manifold (501).

The extinguishing agent, which has already been reduced to a pressure of 200 bar, flows on through the downstream pressure reduction devise (405) where the pressure is further reduced from 200 bar to 60 bar. The INERGEN then flows into the distribution pipe (503) and on to the extinguishing area where it exits the pipe through the extinguishing nozzles (504) and is distributed in the room.

LOCK OFF UNIT FOR SINGLE BANK S YSTEMS

Application And Function The Lock Off Unit can be used to isolate the supply of pilot gas from the main container. It is is located in the actuation line between the pilot cylinder and the pneumatic actuator of the main container as shown in Fig: 2. It is also shown as item 6 in Fig: 3. By closing and locking off the ball valve (C), the source of pneumatic pilot gas is isolated from the pneumatic actuator of the main container therefore preventing it from operating. Under normal operating circumstances the ball valve (C) is locked in the open position, thus ensuring that when a pneumatic source becomes available, at the time of system discharge, the main containers pneumatic actuator is able to operate. The Lock Off Unit consists of a 2/2-directional ball valve with a relief bore hole and built on parts as described in the table below. Two switches can be built onto the device to monitor whether the ball valve is in the open or closed position. For further information please see technical data sheet 5-125-01E. The padlock supplied with the product can be used to secure the ball valve in either of the end positions. The ball valve must be installed in the correct orientation as shown opposite.

Operation and Maintenace If the lock off unit is properly used, it requires no maintainance. Damaged lock off units must be replaced immediately. The warnings in the Operating Instructions for the extinguishing system must be followed. 2

DISTRIBUTION VALVE SY STEM - FUNC TIONAL DESC RIPTION

AREA S WITH IDENTICAL TIME DEL AYS Below is a description based on the the system as shown in Fig 5. If fire breaks is detected inarea the early by the detectors (smokepanel detectors, detectors etc.) (102) positioned in out the itextinguishing and isstages signalled to automatic the detection and control (101).heat Alternatively, a manual release push button (103) is also provided: this is positioned in the extinguishing area and can be operated manually be the staff.

Within the electical detection and control panel (101) the signal from either the automatic detectors (102), or the manual release (103), is processed internally, and initialy the following functions are carried out.

•

The accoustic alarm devices (104) are switched on in the extinguishing area (two independant alarm devices)

•

Visual indicators and alarms, if present, are switched on.

•

An adjustable delay period of between 10 and 60 seconds starts, enabling the staff the leave the extinguishing area. This delay can be achieved in one of two ways, either: a) electonically, by the module in the fire detection and control panel (101), or b) via a stepper motor (106) and controller (101.1) with pulse technology.

•

The air conditioning / ventilation system is swit ched off, together with any operating equipment which may be present such a power supply (107).

•

A signal is given to close doors or other operational enclosures (107)

•

An alarm signal is sent to a permantly occupied location if one has been identified.

•

Other secondary signals are possible on a project specific basis.

After the delay period has elapsed, the actiation signal is given to the components of the extinguishing system: a) signal to the solenoid valve (204.4) responsible for the extinguishing area to be flooded and to the electric actuator (108) for the pilot cylinder (201): or b) signal to the solenoid valve (204.4) responsible for the extinguishing area to be flooded and to the stepper motor (106, which has run out) mechanically opens the cylinder valve (202) on the pilot cylinder (201). In both cases a membrane is destroyed. As a result of this it is no longer possible to close the pilot cylinder valve (202). The pilot gas, INERGEN 200 bar, flows into the ESPL-3 (204). Here the stream of pilot gas is split up into two flows. The first of these flows at full pressure to the transmitter valves (204.7, one per container bank) which are still closed. The second flow, after reducing it’s pressure to 10 bar, flows through the solenoid valve (204.4, one per extinguishing area) which has already opened allowing the flow to continue onto to the pneumatic drive (402) which then opens the associated distribution valve (401). In addition, pilot gas is supplied to the input of the confirmation valve (204.5), which is still closed.

When the distribution valve (401) has reached the ‘open’ position, a signal is sent to the detection and control panel (101) by the position switch (403). After this signal has been processed within the panel the confirmation valve (204.5) for the extinguishing area that is to be flooded is activated.

On opening the 10 bar pilot gas flows automatically via the pneumatic directional valves (204.8.1) in the control unit (204.8) of the EPSL-3 (204) to one or more transmitter valves (204.7). The 10 bar signal is used here to send pilot pressure of 200 bar to the necessary container bank/s which are required to flood the extinguishing area in question. The 200 bar pilot gas flows via the optional ‘Main / Reserve’ switchover unit (205) to the extinguishing agent bank. Example: Extinguishing area A requires bank 1 Extinguishing area B requires bank 2 Extinguishing area C requires banks 1 and 2. The container valves (302) of the corresponding container bank/s are opened pneumatically. The extinguishing agent flows via the pressure reduction unit (303), reduced to a pressure of 200 bar, via the respective container connection hose (304) and the non return valve (305) into the manifold (501). The connection pipe (502) to the distribution valves (401) is connected here. The extinguishing agent, which has already been reduced to a pressure of 200 bar, flows through the opened distribution valve (401) and downstream pressure reduction device (405), which reduces the pressure from 200 bar to 60 bar, and then through the pipe (503) to the extinguishing area where it exits from the extinguishing nozzles (504) and is distributed in the room.

AREA S WITH DIFFERENT TIME DEL AYS Below is a description based on the the system as shown in Fig 5. If fire breaks out it is detected in the early stages by the automatic detectors (smoke detectors, heat detectors etc.) (102) positioned in the extinguishing area and is signalled to the detection and control panel (101).

•

The air conditioning / ventilation system is switched off, together with any operating equipment which may be present such a power supply (107).

•

A signal is given to close doors or other operational enclosures (107)

•

An alarm signal is sent to a permantly occupied location if one has been identified.

•

Other secondary signals are possible on a project specific basis.

After the delay period has elapsed, the actiation signal is given to the components of the extinguishing system: a) signal to the sole noid valve (204.4) responsible for the extingu ishing area to be flooded: or b) The stepper motor (204.6) has run out and opens the integrated control valve mechanically. Due to the activation of the area specific solenoid valve (204.4) or (204.6) the pilot pressure of 10 bar is fed to the pneumatic drive (402) which opens the associated distribution valve (401). In addition, the input of the confirmation valve (204.5, which is still closed) is supplied with pilot gas.

When the distribution valve (401) has reached the ‘open’ position, a signal is sent to the detection and control panel (101) by the position switch (403). After this signal has been processed within the panel the confirmation valve (204.5) for the extinguishing area that is to be flooded is activated.

On opening the 10 bar pilot gas flows automatically via the pneumatic directional valves (204.8.1) in the control unit (204.8) of the EPSL-3 (204) to one or more transmitter valves (204.7). The 10 bar signal is used here to send pilot pressure of 200 bar to the necessary container bank/s which are required to flood the extinguishing area in question. The 200 bar pilot gas flows via the optional ‘Main / Reserve’ switchover unit (205) to the extinguishing agent bank.

Example: •

Extinguishing area A requires bank 1

•

Extinguishing area B requires bank 2

•

Extinguishing area C requires banks 1 and 2.

The container valves (302) of the corresponding container bank(s) are opened pneumatically. The extinguishing agent flows via the pressure reduction unit (303), reduced to a pressure of 200 bar, via the respective container connection hose (304) and the non return valve (305) into the manifold (501). The connection pipe (502) to the distribution valves (401) is connected here.

The extinguishing agent, which has already been reduced to a pressure of 200 bar, flows through the opened distribution valve (401) and downstream pressure reduction device (405), which reduces the pressure from 200 bar to 60 bar, and then through the pipe (503) to the extinguishing area where it exits from the extinguishing nozzles (504) and is distributed in the room.

WELDED DISTRIBUTION PIPE VALVE ASSEMBLY

An means of mounting distribution valves when a fully VdS complient system is not required is by utilising the welded distribution pipe assembly as shown below. See section 3 of this manual for further information on the distribution valve used in the system shown.

Note: The dimension shown for the height to the top of the container fixing bar from floor level (1738mm) is the correct dimension when using 80 Litre containers. The room height dimension shown (2213mm) would be the minimum height requirement of a room used for container storage if standard components are used as shown. This is based on the use of 80 Litre containers and a dimension of 100mm from the centre line of the distribution pipework to the storage rooms ceiling.

ALTERNATIVE A - SCRE WED DISTRIBUTION PIPE VALVE ASS EMBLY LOCK OFF UNIT FOR DISTRIBUTION VALVE

Application And Function The Lock Off Unit can be used to isolate an extinguishing area by inhibiting the automatic operation of the distribution valve associated with that area. The inlet to the lock off device is connected to the distribution valve pilot pipe (A) and it’s outlet (E) is connected to the pneumatic drive of the distribution valve. By closing and locking off the ball valve (C), the pneumatic source required to actuate the the distribution valve’s pneumatic drive is isolated and therefore inhibiting the automatic operation of the distribution valve. Under normal operating circumstances the ball valve (C) is locked in the open position, thus ensuring that when a pneumatic source becomes available, at the time of system discharge, the distribution valve is able to operate. The Lock Off Unit consists of a 2/2-directional ball valve with a relief bore hole and built on parts as described in the table below. A

Two switches can be built onto the device to monitor whether the ball valve is in the open or closed position. For further information please see technical data sheet 5-125-01E.

B

The padlock supplied with the product can be used to secure the ball valve in either of the end positions. The ball valve must be installed in the correct orientation as shown opposite. C

It’s location within the distribution valve arrangement is also shown in the diagram on the previous page. Operation and Maintenace If the lock off unit is properly used, it requires no maintainance. Damaged lock off units must be replaced immediately. The warnings in the Operating Instructions for the extinguishing system must be followed. Technical Data Nominal Diameter

DESIGN DRAWINGS

Following receipt of instructions from the client to proceed with an installation, system layout drawings must be prepared which contain the following information as a minimum: •

Extent of the protected enclosure.

• •

Details of the hazards. Location of the IN ERGEN containers and ass ociated equipment.

•

Position of Pressure Reducing Unit and orifice size.

•

Layout, type and size of pipework.

•

Position of nozzles and orifice size.

•

Calculations to show how the quantity of INERGEN and number of containers were determined.

•

Over pressurisation vent calculations.

Drawings are to be submitted to the client for approval and installation must only proceed against approved drawings.

2.5

ROOM INTEGRITY AND PR ESSURISATION

The successful performance of a Gaseous Total Flooding system is largely dependent on the integrity of the protected enclosure. It is strongly recom mended that a room integrity test is perfor med on any protec ted enclosure to establish the total equivalent leakage area and enable a prediction to be made of the enclosure’s ability to retain INERGEN. The required retention time will vary depending on the particulars of the hazard but will not normally be less than 10 minutes. Longer retention times may sometime s be necessary if enclosures conta in hazards that may readily beco me deep seated. In considering room integrity the designer should be aware that the discharge of any gaseous extinguishing agent into an enclosure will give rise to a change in the pressure within that enclosure, which under some conditions could affect the structural integrity of the enclosure. In most cases the protected enclosure will require a pressure relief device and in all cases the client must be made aware of the pressurisation level expected (from calculation) within the enclosure. In order to calculate the venting area required the formula on the next page may be used:

©2005 TycoSafetyProducts

PAGE 29 of133

INERGEN 300 B ar 14A-09 1.00

16/12/05 CN

In order to calculate the venting area required the following formula may be used:

Q A = -----------------------------------∆P × V HO M

Where:

A Q

= Opening in sq. m = INERGEN flow rate in cu. m/sec*

P = Max. Allowable Pressure Increase in Pascals ** VHOM = Specific Volume of the Homogeneous air / INERGEN mixture (normally 0.77 cm/kg is a good average for 40% concentration) The above formula may be used for simple openings with no ductwork. * As the initial flow of INERGEN is greater at the start of the discharge than at the end, it is necessary to base ‘Q’ on the peak flow rate. The figure used is likely to be 4.5% of the design quantity, but the actual figure used must be taken from the flow calculations. ** A value of 100 Pascal’s should be used if there is no other value offered by the client or clients representative.

2.6

DETECTION AND CONTROL SYSTEMS

Detection and control systems associated with fixed fire fighting systems are outside the scope of this manual. Reference should be made to the applicable company technical manuals and the relevant national standards and code of practice for the operation of fire protection measures pertaining to the electrical actuation of gaseous total flooding extinguishing systems.

ELECTRICAL EAR THING AND SAFETY CLEARAN CES

For guidance on the requirements for earthing and safety clearances refer to the appropriate section of the design standards listed in Section 2.1.

2.8 2.8.1

FLOW CA LCULATIONS SOFTWARE INPUT DATA

Once the gas quantities and nozzle flow rates have been determined, an isometric sketch of the system should be prepared. The sketch will show: 1) The number of containers. 2) The length of every pipe on the system. 3) Node numbers associated with every pipe. A node num ber is given at the follo wing locations: a) Each point in the containe r manifold where the flow from one or more co ntainers enters the mani fold. b) At each change in pipe diameter. c) At each location of a ‘tee’ in the syst em, ie, where the flow rate changes. d) Either side of the o rifice plate. The first container in the system is considered to be node 1. Where the discharge hose enters the manifold is considered to be node 2. Node 3 will be wh ere the second container discharge hose enters the manifold. This continues until the discharge nozzles are reached. At this point the nozzles are given node numbers commencing with the number 301 The program will calculate the pressure drop in the system and will provide pipe diameters, orifice plate sizes and nozzle sizes.

COMPLETING THE SYSTEM DESIGN

Once the program has completed the calculations and the Design Engineer has taken account of any warnings issued, the appropriate nozzles and pressure reducing units are to be ordered. The calculated nozzle and pressure reducing unit orifice areas are used to provide drilling information from the Tables in Sections 2.9 and 2.10.

2.9

NOZZLE DRILLING DETAILS

Tables 9 to 11 details all the available orifice sizes for each type and size of nozzle. When ordering it is necessary to quote the nozzle part number and orifice size. The nozzle pattern used in any system design will depend on the location of the nozzle within the system. The nozzle diameter and orifice diameter used in any system design will depend on the result of the system hydraulic calculations.

INERGEN CONTAINER VALVE - CI 12-8

The CI 12-8 quick action valve is a container valve for INERGEN which can be opened automatically or manually. The automatic opening procedure can be initiated electrically and / or pneumatically. Functional Description of the CI 12-8 Valve

Electrical Release The actuating disk in the valve is punctured by means of Release Head III and actuator SF-2 or the Step Motor SMV-1 delay device. The gas that is released presses the piston downwards so that the valve opens. The valve only closes again when the container has been emptied. Pneumatic Release The valve can be actuated pneumatically via a control cylinder or pilot cylinder. In both cases the pressure is between 200 and 240 bar. Pilot Cylinder Pilot cylinders with a filling pressure of 200 bar are used (maximum developed pressure 240 bar at 50 degrees C) To close the valve, it is necessary to interupt the supply of pilot pressure in the valve and to relieve the pressure. The valve will then close automatically due to effect of the remaining container pressure and the built in closing spring. To protect the container against inadmissible excess pressure (due to the effects of temperature for example) the valve is fitted with a bursting cap with an operating range of between 410 and 450 bar. Valve Components 1) Outlet for extinguishing agent and filling nozzle with protective cap. 2) Connecting cap ASK-2 with intake for pilot gas 3) Test connection (special thread) 4) Safety device for bursting disk 5) Container screwed end: - Max torque: - Recommended sealing material:

SOLENOID ACTUATOR - STANDARD

The SF-2 solenoid actuator is used to electrically operate the container valve. The solenoid is operated at a nominal voltage of 24V d.c. (Power consumption - 15 Watts) and rated to IP65. It is fitted onto the Release Head III by means of a knurled swivel coupling which enables the unit to be positioned as preferred for electrical connection. The solenoid actuator is normally fitted to the container designated as the ‘Pilot’ container. The actuator is an electro-mechanical device which when energised causes the central pin to move downwards, which pushes the central pin of the Release Head III downwards which in turn punctures the burst disc in the valve. Order Number KO 246 032 6

The power lead fitted with a DIN plug for connecting to the solenoid is supplied with the solenoid actuator. Net weight 0.95 kg

SOLENOID ACTUATOR - EXPLOSION PROOF

Indicator

This version of the solenoid actuator is used to electrically operate the container in the same way that the standard actuator does, but it is provided with protection to EEx me II T4, IP65.

The solenoid is operated at a nominal voltage of 24V d.c. (Power consumption - 9 Watts) and is available in other voltages and/or types of current rating.

It is fitted onto the Release Head III by means of a knurled swivel coupling which enables the unit to be positioned as preferred for electrical connection.

The solenoid actuator is normally fitted to the container designated as the ‘Pilot’ container.

The actuator is an electro-mechanical device which has a central pin located within it. When the actuator is energised, the central pin moves downwards, this in turn pushes the central pin of the Release Head III downwards puncturing the burst disk inside the CI 12 quick action valve causing it to open.

Assembly And Installation Notes For Pressure Monitoring Device KM-4

Assembly The pressure monitoring device consists of the following components: •

Contact pressure gauge with connecting cable.

•

Connection piece with special thread to match container valve CI 12-8 and CI 12-6.

The complete unit has undergone a tightness test in the factory. The complete unit is already equiped with a ready made length of cable to enable a simple plug/screw connection on site. The cable length (500mm) is sufficient for connections from one container to another and from one row to another with a system distance of 280 mm, so that all the manometers in one battery block can be looped into one line. The set of accessories for KM-4 is required for the terminal and connection cables. The terminal cable is assembled as described in Technical Data Sheet 5-457-09E.

Installation The contact manometer is fixed directly onto the container valve. When screwing the pressure monitoring device onto the container valve, note that the union nut (SW 19) must only be finger-tightened with the tool. The alarm diode D1 and the LED (Yellow) are allready pre-fitted, to match the the Fast 2000 technology as well as 6350 6351. Adjustments must be made for other technologies in certain cases.

Note: For third-party control panels: The alarm current must be limited to a maximim of 20 mA by resistor R1. Resistor 1 must be calculated for ULED = 2V The terminal resitor RE must always we retro-fitted on site.

To adjust switching point if necessary It is possible to externaly adjust the switching point, to do so use the special spanner on the square shaped head of adjustment shaft and turn to the switching point.

Subject to technical changes.

MANUAL P RESSURE RELIEF VALVE - ELV-1

Application An ELV-1 Pressure Relief Valve is required for each actuation line. The ELV-1 Pressure Relief Valve is used to manualy relieve to atmosphere the residual pilot pressure in the actuation line of an extinguishing system or, in the case of distribution valve systems, the actuation lines of individual battery groups within the system. Use And Maintenance The ELV-1 Pressure Relief Valve is used in conjunction with an Automatic Vent Valve SGV-1, see below. Using a screwdriver, or a similarly shaped object, the relief valve can be activated as shown in Fig 3.xx and by doing so the pilot line will be depressurised. The actuation line must be free of impurities. If used correctly the relief valve is maintenance free. Any valves that become damaged must be imediately replaced with new ones.

AUTOMATIC VENTING VALVE - SGV-1

Application An SGV-1 Vent Valve in conjenction with the an ELV-1 Pressure Relief Valve is required for each actuation line The SGV-1 Vent Valve is used to automatically relieve to atmosphere any minor flows of pilot gas that might occur due to leakage in the pilot system. Such a leak could build up pressure in the actuation line of the extinguishing system or, in the case of a distribution valve system, the actuation lines of the individual container banks within the system, and unles a SGV-1 Vent Valve is utilised this pressure build up could otherwise lead to the accidental discharge of the container bank / extinguishing system. When the pilot sytem is operated the pressure within the actuation line closes the SGV-1 Vent Valve preventing escape of the pilot gas to atmosphere. Therefore the SGV-1 Valve must only be used in conjunction with the ELV-1 Pressure Relief Valve (see above) as this provides a means to relieve the trapped pressure with the actuation line. Use And Maintenance Install at the end of each of each actuation line. The actuation line must be free of impurities. If used correctly the vent valve is maintenance free. Any valves that become damaged must be imediately replaced with new ones. Technical Data Operating Pressure

3.23 TOTAL FLOODING NOZZLE - STANDARD The total flooding nozzles are designed to uniformly distribute INERGEN throughout the hazard area. All nozzles are specifically drilled to suit the individual design requirements as established by the hydraulic calculations. These nozzles are permitted to cover an area of up to 95sq metres based on a maximum nozzle height restriction of 3.7 metres. However, this height restriction can be increase d to 5 metres, but in doing so the area cove rage must be reduced from 95sq meteres to 70sq metres maximum per nozzle. The total volume being protected by one nozzle must not exceed 352 cu. metres. Where the size of any hazard enclosure determines that one nozzle does not provide coverage within the above parameters the hazard should theoretically be sub divided into appropriately sized modules.

Note: For systems fully complying with the VdS standard the area of coverage per nozzle is limited to 30sq metres. In addition only VdS approved nozzles GRD 1/2" and GRD 1” nozzle may be used. Nozzles are available with a 180º pattern or 360º pattern and with either BSPT or NPT thread. The 180º pattern nozzle should not be located in the corner of a room, nor should it be located more than 300mm from the wall.

Orifice Diameter Is Stamped Here

It is recomended that 360° pattern nozzles are placed at least 1 metre away from the wall. Nozzle Weights: 1/2" = 0.05Kg, 1” = 0.15 Kg,

1 1/2" = 0.35 Kg,

The hexagon part of the nozzle is notched to indicate BSPT thread. Chrome plated trim rings are available for 1/2" and 1" nozzles. The maximum throw for a 180° pattern nozzle is 7.775m. The maximum throw for a 360° nozzle is 5.5m.

3.28 PRESSURE REDUCING UNIT - DRE - 3 - DN50 NOT VdS APPROVED (FOR MULTIPLE CONTAINER SYSTEMS) The DRE-3 pressure reducing unit may be used as an alternative to the DRE-2N unit when a system does not need to fully comply with the VdS requirements. The DRE-3 unit reduces the INERGEN pressure from 200 bar to the pipework system design pressure, typically 60 bar max. (the DRE V/S unit located at each container having already reduced the container pressure from 300 bar to 200 bar) The DRE-3 is used on multiple container systems and it is installed between the high pressure manifold and the low pressure nozzle pipework. The required orifice size is established by means of hydraulic calculations at the system design stage. The outlet pipe from the orifice unit must be the same diameter as the orifice unit, reduction of the pipe diameter at the exit of the orifice plate unit is not permitted.

3.31 DISTRIBUTION VALVE ASSEMBLY - HD-BV / 3 (VdS SYSTEM S) The type HD-BV/3 high pressure distribution valve assembly is closed and unpressurised when in standby mode. The HD-BV/3 high pressure distribution valve assembly performs two duties, it acts as both a distribution valve and a pressure reduction unit (200 bar to 60 bar) by utilising the orifice plate that is included as part of the HD-BV/3 assembly. The required orifice size is established by means of hydraulic calculations at the system design stage. The valve will open after the integrated activation device has been triggered. Once open, the distribution valve allows INERGEN to flow into the pipe network it’s respective extinguishing area. Theareas. remainder of the distribution valves remain closed and therefore prevent flow for of INEGEN into the other extinguishing In order to open the distribution valve the attached pneumatic actuator is exposed to pilot gas at a pressure of 10 bar. After a discharge, the distribution valve is closed manually, for details of this please see the relevant operating instructions. The outlet pipe from the orifice unit must be the same diameter as the orifice unit, reduction of the pipe diameter at the exit of the orifice plate unit is not permitted. B

3.34 PILOT CYLINDER Pilot cylinders are filled with INERGEN gas and are pressurised to 200 bar. They are used in conjunction with the release head III to pneumatically operate the main container of the INERGEN fire suppression system. A pilot cylinder can also be actuated manually, using the local manual actuator and release head III. It may also be actuated electrically using the solenoid actuator or the step motor delay device, again in conjunction with release head III. If the INERGEN fire suppression system is designed to utililise distribution valves, a pilot cylinder may also be used to operate a distribution valve as well as the main container for the associated area. Pilot cylinders are manufactured in accordance with 99/36/EG (TPED) and are pressure tested to 250 bar. pilot cylinders are coloured grey to EN 1089 with a bright green top dome. The Cylinders are fitted with the CI 12-6 container valve, which has a nominal burst disk rating of 270 Bar. (At 70 degrees C, +30 bar - 10 bar. At 20 degrees C 300 bar maximum)

INSTALLA TION INFORMATION

This section provides general guidance on the installation of INERGEN Fire Fighting Systems. However, it is of paramount importance that persons involved in the installation of this equipment have had previous experience in the installation of this or similar equipment. Appropriate items of safety equipment such as safety shoes should be worn by those involved in the installation work. Equipment is to be installed in accordance with an approved drawing. It is not permitted for changes to equipment, pipework or nozzle positions to be made without the authority of the Extinguishing Systems Design Engineer. It should be noted that special components have been designed to allow for the safe assembly of the high pressure side of the installation (the sections up to and including the pressure reducing units). •

Under no circumstances should alternative components be used in this part of the installation.

The components are supplied with a variety of left hand (referred to as L), right hand (referred to as R) and left and right hand threads (referred to as RL etc.) to ease assembly. All left handed threads are identifiable by a groove around the circumference of the component. Gas tight seals are made using O-rings. All O-rings should be lubricated with non-acidic grease. O-rings required to make gas tight seals are supplied as part of union joints/pressure reducing device and do not need to be ordered separately.

4.1

DELIVERY AND HANDLING OF EQUIPMENT 1)

Check all equipment delivered against the Despatch Note. Notify the extinguishing stores immediately if there is any discrepancy between the equipment received and that indicated on the Despatch Note.

2)

Store all equipment in a dry room a t a temperature between 0°C and 50°C and protect from direct sunlight, until it is required for installation. Keep containers upright and secure them so that they cannot fall over. •

3)

It is usual for, but not essential, for the installation to start with the fitting of the containers. To move INERGEN containers use a trolley and if containers are to be raised over steps etc; ensure that appropriate lifting gear is employed. Under no circumstances must containers be rolled or dropped into position. •

4.2

Make no attempt to move INERGEN containers unless they are fitted with transport caps and anti-recoil caps.

Until containers are fully connected into a com pleted pipework system the tran sport caps must not be removed except temporarily to allow for the fitting of the container retention ring.

CONTAINER FIXING 1)

The container bank will be constructed to allow fitting to wall/supporting structure or ‘free-standing’ using the appropriate components detailed in the manual. Follow the instructions below depending on which fixing method is required.

2)

Check that there is at least 300mm free access at the ends of the container bank, and at least 1000mm free access at the front of the bank.

3)

Ensure that the floor and walls are flat. If it is suspected that the floor is likely to become wet, place the containers on metal grating to keep them off the floor. The metal grating will raise the height of the bank by 30mm.

4)

The container bank will be made up of one or more manifolds. Manifolds come in two types:

6)

For 'free standing' container banks, mark the position of the free standing posts on the floor and fix to the floor. Use a spirit level to ensure that the post is vertical. Bolt the retaining bar(s) to the post and then fix the other free standing post.

7)

Bolt the two manifold brackets to the retention bars in the appropriate place.

INSTALLI NG MANIFOLDS 1)

On systems using between one and two rows of containers the following steps will require to be completed. To install the manifold, check that the end cap has an 'O' ring fitted, screw the end cap onto the manifold by hand. Ensure that the fitting is screwed fully home.

2)

Check that the union joint has an 'O' ring fitted and screw the union joint onto the other end of the manifold. Ensure that the fitting is screwed fully home.

3)

Locate the manifold onto the manifold fixing brackets. Manifold fixing brackets are positioned at either end of the container bank. They are bolted to the retention bar and fix the manifold at the end cap or union joint. The 560mm pipe is screwed into the union joint, please see diagram below. The orifice plate is then screwed onto the 560mm pipe. If the container bank has more than two rows of containers then there will be a second row of manifolds and free standing posts will be required. A high pressure tee and elbow will be required for the assembly. Consult the approved working drawing for the specific layout.

Note:

65mm pipe clamps should be used for 50mm unions and 100mm pipe clamps for 80mm unions A > 0mm

A + B = 5mm

B > 0mm

Checking the correct installation of HF fitting.

4.4

INSTALL ING DISTRIBUTION PIPE AND DISTRIBUTION VALVES ALTERNATIVE A - NON VdS APPROVED SYSTEM 1)

If the system has distribution valves then a two way, three way (or combination of both) distribution valve manifold may be used. These are connected to the manifold with a union joint, please see the diagram above. To reduce the height of the distribution valves a down pipe may be used. This is fitted between the manifold and the distribution valve manifold and reduces the height of the distribution valves by 1392mm.

2)

Use a 'pair of distribution pipes' (302.402.576) to fit either side of the distribution valve. Connect the 2" ISO left hand thread into the distribution valve manifold using a union joint. The other end of this pipe has a 2"NPT end. Screw this into the distribution valve. The other pipe has 2" NPT at one end and 2" ISO right hand at the other. Screw the 2" NPT into the distribution valve and the 2"ISO into the orifice plate. There will be one pair of distribution valve pipes for each distribution valve.

INSTALL ING THE PRESSURE REDUCING UNITS ALTERNATIVE A - NON VdS APPROVED SYSTEM 1)

Check against the drawing that the correct sized orifice has been supplied.

2)

Observe the following procedure to ensure correct assembly of the pressure reducing unit:

3)

Ensure that the orifice plate, circlip and ‘O’ ring are properly installed into the unit. Screw the unit onto one of the pair of distribution pipes. This will be the 2" ISO right hand thread. Do not overtighten. The system pipework can now be installed from this point.

4.6

INSTALL ING DISTRIBUTION PIPE AND DISTRIBUTION VALVES ALTERNATIVE B - VdS A PPROVED SYSTEM

Connection and all pipework up-stream of selector valves is classified as high pressure piping and HF fittings must be used as specified in Data Sheet 5-433-04. •

Fabrication of high pressure piping and components on site is not allowed.

For assembly of fittings and pipes see the diagram below. Installation should preferably follow the direction of gas flow. Special attention should be paid to the following: •

Two sizes of elbow are available, DN50 and DN80. Both of them have left and right hand threads.

•

Pipe is stocked in 560mm lengths in DN50 and DN80 sizes.

•

Special pipe can be supplied in lengths from 170mm.

•

From reducing or increasing diameters for 50mm to 80mm, a 80 x 50 x 80 Tee must be used, with one outlet capped if necessary. The distribution pipe below the selector valve must be supported at the first and last union joints and also between every two selector valves. Standard support brackets are available. See exploded view on page 25 of this manual.

•

•

All connection pipe between the main manifold and the selector valve distribution pipe must be supported so as to avaoid any instability, especially at changes of direction. This could happen because of the easily rotable o-ring seals. Pipe clamps and brackets should be used. Supports shall be fitted to the union joints and not directly to the pipework or tees.

Note: 65mm pipe clamps should be used for 50mm unions and 100mm pipe clamps for 80mm unions A > 0mm

A + B = 5mm

B > 0mm

DISTRIBUTION VALVES AND PRESSURE REDUCING UNITS

Note: The connection pieces seal well when hand tightened with a friction wrench. Do not overtighten. All o-rings should be smeared with grease, we recomend Molykote paste G-n. 1)

The distribution valves valves are fitted to the distribution pipe between flanges. The lower flange is fitted to the outlet of the tee on the distribution pipe via a greased o-ring joint. The correct position of the bolt holes is shown in the diagrams below.

Incorrect Flange Allignment

Correct Flange Allignment

2)

Insert the appropriate o-ring into the groove in the top of the flange.

3)

Before each flange is placed on the flange, temporary means should be used to support the weight of the pneumatic drive.

4)

The next o-ring is now fitt ed, together with the orifice plate (with the correctly drilled orifice for the zone in question)

5)

The upper flange is now placed on top of the orifice plate, with another greased o-ring.

6)

The two flanges are now bolted together and tightened to the appropriate torque.

7)

The low pressure system piping can now be screwed to the upper flange and fixed.

8)

The temporary support may now be removed and the next valve installed.

9)

Once all the valves are in place, the lock off unit for each valve is installed by clamping it to the piping above the selector valve. It is connected to the pneumatic drive of the selector valve.

Since all the components in a 300 bar system from the manifold to the distribution valves are fully pressure tested and the HF series of fittings is approved by VdS, it is not necessary to carry out pressure tests on site. To check correct assembly, a leakage test should be carried out at 2 bar using INERGEN. See stage 1 of instruction 5-037-03 for details. This test report must be recorded in a written report and signed by the responsible supervisor. •

4.8

Warning: Water should not be us ed to test th e pipework since it would pe netrate into the s mall cavities of the o-ring seal units and be difficult to remove.

INSTALLING THE CONTAINERS 1)

When the containers are in the general vicinity of the ‘container’ bank, unscrew the transport cap, screw on the container retention ring, and screw the transport cap back on. The threads on the container retention ring must be fully engaged by the threads on the container to ensure that upon fixing the container will be securely fastened.

2)

Secure the first container to the retention bar with the fixing links provided. Bring the next container into position. Ensure that the retention ring is at the same height as the first container, and secure this container to the previous container and retention bar. Continue with the installation of all containers in the bank in a similar manner.

4)

For the purpose of this manual the checking of th e actuation lines are shown in the commissioning section, but the checks may be carried out during installation (if so, the commissioning section should be consulted at this stage).

All threads on the actuation lines are to be torqued as follows: •

Threads with O-ring seals:

•

Metal to metal seals:

10Nm

•

These torques must not be exceeded.

40Nm

5)

Fit the container pressure indicators to the valves. These are fitted hand tight and should give a pressure reading when correctly fitted.

6)

Use soap solution to check that the seal is tight. If necessary, use a spanner to tighten the connection by up to one quarter of a turn and then test again. •

Do not over-tighten as this could damage the O-ring.

COMMISSIONING INFORMATION

This section provides guidance on the commissioning of INERGEN Fire Fighting Systems and is in the form of a check list to be completed by the person carrying out the commission ing. The commissioning schedule (Document 14A-08-C1, an example of which is shown on pages 100 to 108) is intended to cover the majority of the equipment or configurations likely to be encountered, however, where appropriate it may be necessary to carry out additional checks to those listed. All sections must be completed, or if not applicable, write N/A in the appropriate space. It is essential that persons carrying out commissioning of INERGEN systems are experienced in the commissioning of this type of equipment. Container pressures adjusted for temperature are to be checked for compliance using Table 35, Page 100. Pages 101 to 108 are an example of the schedule to be completed by the responsible person. The schedule is to be completed during the commissioning of all new systems and those that have been modified.

5.1

CHECKING THE PNEUMATIC ACTUATION LINES 1)

The actuation lines on the INERGEN container arrangement must be configured using the components detailed in section 3.21.5 of this manual and as detailed in the installation section (Section 4) and as such a pressure test is not required.

2)

Any other sections of actuation tubing ie, actuation tubing from pilot cylinders to distribution valves are to be tested by carrying out a functional test on these lines by discharging a charged pilot cylinder to confirm satisfactory operation of the distribution valves and any associated devices. •

During this operation (to prevent accidental operation of the INERGEN containers) the pneumatic actuators are to be removed from thelines containers. lossbe of safely actuation pressure should occur during this process and the actuation should No then vented by manual operation of the bleed valve.

3)

5.2

Following completion of these tests the distribution valves will need to be manually closed and all actuators reset prior to refitting to the containers.

CHECKING OPERATION OF SOLENOID, PNEUMATIC AND LOCAL MANUAL A CTUATORS 1)

Read Sections 3.60 to 3.10 before proceeding.

2)

Prior to carrying out any tests on any actuator, ensure that they are disconnected from the INERGEN container.

3)

Check that the resetting tool is available for tests on the solenoid actuator.

4)

Electrical, manual or pneumatic operation of the above devices is confirmed by the movement of the central pin.

5)

After testing and before fitting to the container valve ensure the central pin is in the fully retracted position.3.8 The solenoid resetting tool is required to reset the solenoid after each operation. (See also Section

Upon completion of commissioning of the system, confirm in writing, any defects or actions arising, to the responsible person within the company or the client’s representative as applicable. A copy of the completed commissioning schedule and any correspondence arising from defects or outstanding actions must be retained in the project file. As soon as reasonably practicable after commissioning, ensure a ‘User Manual’ and ‘As Installed’ drawings are sent to the clients representative and such transmission is recorded/confirmed in writing. Confirm in writing the client’s responsibilities in respect to over pressurisation venting.
