9. AUXILIARY INPUTS & OUTPUTS
9.1 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 4 conventional sounder outputs & any loop powered
sounders.)
Typical auxiliary input wiring options

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.
9.2 AUXILIARY OUTPUT WIRING (VOLTAGE FREE CHANGEOVER
CONTACTS)
Auxiliary Fire Output
(AUX): Changes over in any fire condition, and be used for driving local fire
fighting equipment such as sprinkler systems, magnetic door holders, air conditioning shut off, etc.
Fault Output
(FAULT): This Output is energised in the quiescent condition. In a fault condition, the
output relay turns off, to ensure failsafe operation even in the event of total power loss. That is, the
normally open contact will be closed when there is no fault, and open when there is a fault. This
should be taken into account when any device is connected to the fault relay.

The fault relay is used to
connect to a remote
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.
