Fan Termination Board BRD25FTB
The Fan Termination Board interfaces between the Fire Fan Module and the plant/equipment it
controls via the 24 volt 250mA Start, Stop, current limited, relay outputs and monitor inputs.
Programmable monitoring of the field equipment is achieved using 0 volts as an input level to
indicate run, fault and stop conditions of that equipment. Monitoring is programmed in the
Function Menu for a 3, 4 or 5 Wire Start / Stop, Run, Fault, Stop & Common functions. The inputs
are protected by way of resetable transorbs and resistive / capacitive networks.
Quiescent Current: 6.5mA

General Indicator Card BRD25GIB -A
IMPORTANT
Note:
The Cards BRD25GIB –A, B, C and D all have a common PCB. What sets them apart from
each other is not only the function they perform but how the componentry is loaded onto the card
to perform that function.
This Card indicates / displays the status of the inputs on the 16 Way Input Termination Board by
way of Program selectable tri-coloured LED’s with its function being identified on the front panel
by slip in labels.
Quiescent Current:
3 to 3.5mA depending on the application
