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.

no. F765 in Figure 28 page 155.

Stopped
Fan Stopped -
Green
Illuminates when the fan is stopped.
Fault Fan Fault - Yellow
Illuminates when the signal to change the fan status is restored,
either via manual override switch or by the FDCIE in Auto mode but
the feedback signal confirming the change of state has not been
received by 3361 input in the field within 30 seconds.
Or
There is an open circuit in the 3361 supervised input (when set to
be supervised) where the feedback from the pressure switch is
connected.
Or
The pressure switch is faulty
On
LED – Red Illuminates when the “On” button is pressed, fan starts up manually
Button

4.3 Zone Control & Indication Module
The Zone Control Module is used as a simple and easy access to disable (isolate)
individual zones for service and maintenance purposes as well as providing zone alarm
and zone fault indications. The front display layout is shown in Figure 5 below.
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 refer to the Technical / Programming Manual and to drawing no.
