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.)

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.
4.7 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.
