Overview of the EMUA

About This Chapter Applicable to all types of BTSs/NodeBs manufactured by Huawei, the outdoor environment monitoring unit (EMUA) is used to monitor the environment in the equipment room and the cabinet. 2.1 Functions of the EMUA This describes the functions of the EMUA. Providing a variety of input ports for monitoring signals, the EMUA supports real-time monitoring and remote monitoring. In addition, the EMUA is highly reliable and can be flexibly configured. It supports a large area for temperature monitoring. 2.2 Exterior of the EMUA Each Module of EMUA has three types of exterior A, B, and C. 2.3 Internal Structure of the EMUA This describes the internal structure of the EMUA. 2.4 Communication Ports on the EMUA The EMUA provides the RS485 and RS232 ports for the communication between the EMUA and the BTS/NodeB. Specifically, the EMUA4832 provides an independent commissioning port. 2.5 Monitoring Ports of the EMUA The EMUA provides monitoring ports for the humidity/temperature sensor, smoke sensor, water sensor, infrared sensor, and door status sensor. In addition, the EMUA provides monitoring ports for the Boolean signal sensor, analog signal sensor, and output control sensor, which are extended sensors. 2.6 Technical Specifications of the EMUA This describes the technical specifications of the EMUA.

2.1 Functions of the EMUA This describes the functions of the EMUA. Providing a variety of input ports for monitoring signals, the EMUA supports real-time monitoring and remote monitoring. In addition, the EMUA is highly reliable and can be flexibly configured. It supports a large area for temperature monitoring.

Functions of the EMUA Power Input The EMUA supports input voltage detection. The alarm threshold for the input voltage can be configured on the BTS/NodeB and delivered to the EMUA. The EMUA provides two power input ports, which are protected from inverse connections. l

The EMUA2416 and EMUA2432 support +24 V DC power input, and the voltage can range from +18 V DC to +36 V DC.

l

The EMUA4832 supports -48 V DC power input, and the voltage can range from -36 V DC to -72 V DC.

Environment Monitoring l

The EMUA provides an independent port for +12 V/+24 V DC current-type (4 mA - 20 mA) humidity/temperature sensors. The temperature monitoring range is -20oC [-4oF] to 80oC [176oF].

l

The EMUA provides four ports for monitoring analog signals. Voltage-type (0 V - 5 V) sensors and current-type (4 mA - 20 mA) sensors can be used. The types of monitored analog signals can be configured through the DIP switch settings according to the BTS/ NodeB configuration.

Boolean Signal Monitoring The EMUA provides ports for monitoring Boolean signals. Dry contact point signals and OC signals are supported. l

The EMUA2416 supports 16 ports for Boolean signal monitoring.

l

The EMUA2432 or EMUA4832 supports 32 ports for Boolean signal monitoring.

Relay Node Control The EMUA provides six output control ports for external Boolean signals of the relay node type. Communication Ports The EMUA provides two RS-485 ports, which are used for the communication between the EMUA and the BTS/NodeB.

Comparison Between the Functions of the Three EMUA Models Table 2-1 lists the functions of the three EMUA models for you to make a comparison.

l

If a DIP switch bit is set to ON, it represents 0. If a DIP switch bit is set to OFF, it represents 1.

l

The settings of the DIP switch SW_ADDR (1234) are as follows: –

Outdoor CDMA BTS: 0000

–

Indoor CDMA BTS or non-doubledensity GSM BTS: 0001

–

Double-density GSM BTS, WCDMA NodeB or LTE eNodeB or WiMAX BTS (the EMUA does not support alarm association): 0010

–

Double-density GSM BTS, WCDMA NodeB or LTE eNodeB or WiMAX BTS (the EMUA supports alarm association)：1110

NOTE l If an EMUA is delivered along with the BTS/

NodeB, the communication protocol is already configured according to the BTS/ NodeB type. l If an EMUA is delivered independently, the

default setting of the DIP switch SW_ADDR (1234) is 0010. l If an EMUA must support alarm association,

the DIP switches must be set on site.

2.4 Communication Ports on the EMUA The EMUA provides the RS485 and RS232 ports for the communication between the EMUA and the BTS/NodeB. Specifically, the EMUA4832 provides an independent commissioning port. 2.4.1 RS485 Serial Port This describes the RS485 serial port on the EMUA. The RS485 serial port supports two ports (active/standby mode) for the communication between the EMUA and the BTS/NodeB. The RS485 serial port is suitable for a dedicated serial port that has a DB-9 male connector. 2.4.2 RS232 Serial Port This describes the RS232 serial port on the EMUA. An RS232 serial port is an RJ-45 socket and suitable for a dedicated serial port cable that has an RJ-45 plug. 2.4.3 Commissioning Serial Port This describes the commission serial port of the EMUA4832. Of all the EMUA models, only the EMUA4832 provides a commissioning serial port. The commissioning serial port is used Issue 10 (2010-03-30)

Figure 3-5 Exterior of the HO-03A door status sensor

NOTE

The cable provided along with the HO-03A door status sensor is 10 m [32.81 ft] long.

Working Principle of the Door Status Sensor When the button at the top of the AGX105F door status sensor is pressed, the spring is compressed, and the reed touches pins A and B, as shown in Figure 3-6. Figure 3-6 Working principle of the AGX105F door status sensor

The HO-03A door status sensor consists of a dry finger pipe and a magnetic ferrite. The dry finger pipe consists of two soft magnetic metal fingers that are close to each other. When the magnetic ferrite is close to the dry finger pipe, the fingers are magnetized and attracted to each other. When the magnetic field no longer covers the fingers, the fingers spring apart.
