EMERGENCY LIGHTING SYSTEM PRESENTATION General

L0Y06082 - L0DT0T0 - LM33P5000000001

The emergency lighting system is designed to give sufficient illumination to the cabin, to identify the emergency exit areas and to fulfil safe and quick escape from the A/C in emergency conditions. The system must be efficient in darkness and/or in case of smoked cabin, even if no A/C power supply is available. The Emergency Power Supply Units (EPSUs) are the heart of the emergency lighting system. They interface with the cockpit crew, the cabin crew, the Cabin Intercommunication Data System (CIDS), some A/C systems and the emergency lights. The lights are composed of: - the cabin ceiling emergency lights, - the staircase emergency lights, - the cockpit way lights, - the floor path marking system - the emergency slide lights, - the emergency door lights, - the exit signs. Note that to reduce operating costs and to improve reliability, all emergency lights use Light Emitting Diode (LED) technology.

EMERGENCY LIGHTING SYSTEM PRESENTATION General Architecture

L0Y06082 - L0DT0T0 - LM33P5000000001

The emergency lighting system can be controlled manually, either from the cockpit by the EMERgency EXIT LighTs and the cockpit way light switches, or from the cabin by the EMERgency lighting switch on the FAPs and a second cockpit way light switch. It can also be controlled automatically according to the A/C configuration by the CIDS network and by some A/C systems like the Doors and Slides Management System (DSMS) and the Electrical Power Generation System (EPGS). In all cases, the emergency lighting system is electrically powered by the EPGS through 18 EPSUs. If no AC power is available, each EPSU is able to supply the attached emergency lighting components for at least ten minutes of operation thanks to its integrated battery.

L0Y06082 - L0DT0T0 - LM33P5000000001

The Floor Path Marking System (FPMS) will guide the passengers to the next exit under smoke conditions. The system is composed of - the seat mounted floodlights for illumination of the main aisles, - the wall mounted floodlights for illumination of areas in front of monuments like galleys and lavatories, - the edge mounted floodlights for illumination of areas in front of monuments, used in narrow places where seat mounted floodlights do not fit, - the exit identifiers for illumination of door areas. Each FPMS component uses LED technology and is powered for redundancy reasons by two EPSUs when the emergency lighting system is activated manually or automatically from the related activation devices.

LIGHTS SYSTEM MAINTENANCE (1) Lights System Safety Items

L0Y06082 - L0DT0T0 - LM33P6MAINT0001

When you work on the lights system, make sure that you obey all the AMM safety precautions. This will prevent injury to persons and/or damage to the A/C. Here is an overview of the main safety precautions relative to the lights system. High Intensity Discharge (HID) lamps contain mercury. If an arc tube breaks, it is possible that the operator absorbs some mercury through the skin. In consequence, always wear safety gloves. HID lamps have very high temperature in working condition; 800°C on the outer bulb and 240°C on the base. To prevent burns, let the bulb cool down for three minutes after the switching off and disconnection before removal. HID lamps emit some UV rays. Thus, as a precaution, always wear safety UV glasses because of sunburn and conjunctivitis issues. The capacitor in the electrical circuit of the strobe light can keep a high voltage charge for some minutes. In consequence, do not remove the strobe light for a minimum of ten minutes after you de-energize the electrical circuit.
