It supportsa large area for temperature monitoring.

Power Inputl The EMU supports input voltage detection. The alarm threshold for the input voltage can

be configured on the BTS/NodeB and delivered to the EMU.

l The EMU provides two power input ports, which are protected from inverse connections.

l The range of voltage input is -36 V DC to -72 V DC.

Environment Monitoringl The EMU 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 EMU 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 monitoredanalog signals can be configured through the DIP switch settings according to the BTS/NodeB configuration.

Boolean Signal Monitoring

The EMU provides 32 ports for monitoring Boolean signals. Dry contact point signals and OCsignals are supported.

Relay Node Control

The EMU provides six output control ports for external Boolean signals of the relay node type.

Communication Ports

The EMU provides two RS-485 ports, which is used for the communication between the EMUand the BTS/NodeB.

2.4 Communication Ports on the EMUThe EMU provides the RS485 and RS232 ports for the communication between the EMU andthe BTS/NodeB.

2.4.1 RS485 Serial PortThis describes the RS485 serial port on the EMU. Two RS485 serial ports are used in active/standby mode for the communication between the EMU and the BTS/NodeB. The RS485 serialport is suitable for a dedicated serial port that has a DB-9 male connector.

2.4.2 RS232 Serial PortThis describes the RS232 serial port on the EMU. An RS232 serial port is an RJ-45 socket andsuitable for a dedicated serial port cable that has an RJ-45 plug.

2.4.1 RS485 Serial PortThis describes the RS485 serial port on the EMU. Two RS485 serial ports are used in active/standby mode for the communication between the EMU and the BTS/NodeB. The RS485 serialport is suitable for a dedicated serial port that has a DB-9 male connector.

For the position of the RS485 serial port on the EMU, see 2.2 Exterior of the EMU.

l When the TXD+ pin is connected to the RXD+ pin and the TXD- pin is connected to the RXD- pin,the RS485 serial port can be used for two-wire connection.

l The EMU works properly even if only one RS485 serial port is connected. It is recommended that youuse two RS-485 serial ports in active/standby mode. In this case, set serial port 1 to the active port.

2.4.2 RS232 Serial PortThis describes the RS232 serial port on the EMU. An RS232 serial port is an RJ-45 socket andsuitable for a dedicated serial port cable that has an RJ-45 plug.

l Before powering on the smoke sensor, ensure that the smoke sensor is correctly connected.Thirty seconds after the smoke sensor is powered on, the red indicator will start to blinkonce every 9 to 15 seconds.

l Dust easily accumulates on the smoke sensor. Therefore, clear the dust periodically to avoidfalse alarms.

l To protect the smoke sensor from dirt, do not remove the dust cover before using the sensor.

CAUTIONl The smoke sensor cannot work without the power supply. Therefore, the smoke sensor does

not work if the power supply is interrupted.l To avoid damage to the smoke sensor, do not directly use +24 V DC input voltage for the

smoke sensor.

NOTE

l The smoke sensor can be connected only to the terminals marked "Smoke&24VS".

l The smoke sensor generates alarms when there is smoke or fire. You have to run an associated commandto clear the alarms.

6 Commissioning the EMU

This describes how to commission the EMU.

Procedure

Step 1 Perform a power-on check for the EMU.1. Check the DIP switch settings.

For the correct DIP switch settings, see 2.3 Internal Structure of the EMU.2. Power on the EMU.3. Check the status of the indicators.

After power-on, both the red and green indicators should blink for about 0.5 second. Then,the red indicator should be off, and the green indicator should continue blinking.

Step 2 Check the communication between the EMU and the BTS/NodeB.1. Ensure that the EMU has passed the power-on check.2. On the Service Maintenance System of the BTS/NodeB, establish the communication

between the BTS/NodeB and the EMU.3. Check the status of the indicators on the EMU.

Check that the green indicator on the EMU blinks once every two seconds.

Step 3 Check the running status of the EMU.1. Ensure that the EMU has passed the communication check.2. Read the data of the sensors and the voltage on the Service Maintenance System of the

BTS/NodeB.

Check that the data is correct.
