External Alarms
10 External Alarms
The RBS 2106 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 must be isolated by 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 during installation, 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.
