6.5 Fire Fan Module BRD25FCB
The Fire Fan Module has four ( 4 ) separate fan controls each having an On, Auto and Off function switch
and a set of three (3) monitoring LED’s. The LED’s indicate the status of the equipment eg. Run, Fault or
Stop. The two ( 2 ) arrow head keys are used to step up and / or down through the three ( 3 ) conditions. A
slip in label can also be inserted into the hinged cover for identification purposes.
A loop driven version is also available (159-0105 )
☞
Note#: As per AS 1668.1 1991, Clause 14.17.4 lettering on any of the slip in labels must be at least
5mm in height.

6.6 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.
Connectors
CN5 Is used for factory programming only and may not be available on all boards.
