4.5 AUXILIARY INPUT WIRING EXAMPLES
There is one non-latching auxiliary input connection on the Fire Alarm Panel.
Class Change Input (CC): This will energise all alarm outputs continuously when the CC terminals
are shorted together. (This includes the addressable sounders, sounder bases. The auxiliary fire
relay driver is NOT activated by the Class Change input.)

The termination for the above inputs must be as indicated on the main PCB (See page 15). The
Earthing of the cable screens should be as shown on page 9.
4.6 AUXILIARY OUTPUT WIRING (24V Relay Drive Outputs)
Auxiliary Fire Output (AUX): Supplies 24V in any fire condition. This is used to drive a 24 volt relay
(coil voltage), which can be connected to emergency lights, local fire fighting equipment such as
sprinkler systems, magnetic door holders, air conditioning shut off, etc. More than one relay can be
connected to this output if required.
Fault Output (FAULT): Gives 24V in the quiescent condition, and 0V in a fault condition. This
ensures failsafe operation even in the event of total power loss. More than one relay can be
connected to this output if required.

indication device
The fire relay can be used to connect
to various devices which are activated
on a fire alarm. Eg. Auto dialer ,
magnetic door release (24V), sprinkler
system etc.
