Reference Manual Part 1

RBS 2206

• TMR 9202

The connectors used for this are:

• PCM cables

• +24 V DC cables

• Blank panels for connectors to the OXU

9 External Alarms

The RBS 2206 supports a maximum of 16 external alarms. The external alarm

device can set the alarm using either an open or a closed condition.

The alarm device connected to the screw terminals should be isolated relay

contacts. A closed contact (logic zero) is required to be below 2 k

, and an open

contact (logic one) above 100 k

. The current through a closed 0 W contact is

1.2 mA. The voltage between terminals with an open contact is 24 V DC.

The external alarms are defined at the installation. They are defined by using

the OMT or from the BSC using the remote OMT.

Note: An installed DC/DC Converter is hard-coded to alarm input 16 in the

External Alarm Unit. Pin 16 is therefore unavailable.

Note: An installed Smoke detector is hard-coded to alarm input 2 and 3 in the

External Alarm unit. Pins 2 and 3 are therefore unavailable.
