Note: the total number of fan modules must be reduced by one for every other option
fitted, e.g. zone module, generic module, expansion board, etc.
A fan reset switch is provided to independently reset the fan module as required by
AS1668.2 i.e. reset the alarm in the FDCIE will not restore the fans to the non-fire condition
until the reset switch is pressed.
A remotely located (mechanical services) 3361 module is required for each fan and
configured in the control panel using EBLWin. For standard fan configuration e.g. smoke
exhaust fans, the simple standard mode can be used to program 3361 while for more
configuration options e.g. supply air fans, the enhanced mode can be used.
The I/O matrix board 4582 is a COM loop unit which can be fitted with the front display
board inside the control panel or remotely in a separate enclosure.
For more information refer to FT128 Technical / Programming manual and to drawing no.

4.3 Zone Control & Indication Module
The zone control module is used as a simple and easy method to disable (isolate)
individual zones for service and maintenance purposes as well as providing alarm and
fault indication for these zones. The front display layout is shown in Figure 5 .
Each zone control module consists of a universal I/O matrix 4582 and application board
SUB900 specifically configured to provide up to 12 individual zone alarm and zone fault
indicators as well as a disablement control with indicator to indicate switch activation. The
module is normally mounted in the FDCIE. but it is also possible to connect the module
externally via a COM loop.
The disable control allows a specific zone to be temporarily disabled without the need to
access the FDCIE menu. This is typically used where building works or maintenance
procedures are being carried out in a localised area of a building. For more information
