(This includes the 4 conventional sounder outputs & any loop poweredsounders.)Typical auxiliary input wiring optionsCLASSCHANGE 2nd Fire AlarmAUX FIRE RELAYCM NOCLASSCHANGEThe termination for the above inputs must be as indicated on the main PCB (See page 15). TheEarthing 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 firefighting 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, theoutput relay turns off, to ensure failsafe operation even in the event of total power loss. That is, thenormally open contact will be closed when there is no fault, and open when there is a fault. Thisshould be taken into account when any device is connected to the fault relay.Typical auxiliary output wiringNO CM NCFAULT RELAYFAULTINDICATIONDEVICENOTE: THE NC CONTACTIS OPEN WHEN THERE ISNO FAULT.Trigger I/PNO CM NCFIRE RELAYAUTO-DIALERTrigger I/PThe termination for the above inputs must be as indicated on the main PCB (See page 15).
