Section 6 – Fire Detection and Alarm SystemsGeneral InformationSection 6 of AS1851-2012 covers: Fire Detection and Alarms Systems Electrical Detection and Control Systems for: Special Hazards Systems; and Smoke Hazard Management Systems Smoke and Heat Alarms Emergency Warning Systems Emergency Intercom Systems Occupant Warning Systems

Section 6 – Fire Detection and Alarm SystemsPrecautions Prevent adversely affecting the normal operation of anysystem, except for those systems to be serviced. Inform responsible person on-site that activities mayadversely affect the occupants or operations of thebuilding. Inform the responsible entity of the expected duration ofthe impairment so that alternative safety arrangementscan be implemented Notify the monitoring service provider where testing orservice may cause signals to be transmitted. This could include configuring the alarmsignalling equipment to test mode and confirmnormal operation at completion

Appendix F – Battery Capacity TestingDetermining Required Battery CapacityThe battery capacity requirement shall be determined as follows:a) Determine the quiescent load current (IQ).b) Determine the alarm current (IA).c) Determine the capacity de-rating factor (FC) of the battery when dischargedat the alarm load rate.

Appendix F – Battery Capacity TestingDetermining Required Battery CapacityThe battery capacity requirement shall be determined as follows (cont.):d) The 20 h discharge battery capacity C20 at 15 C to 30 C shall be determinedas follows:C20 L[(IQ TQ) FC (IA TA)]whereC20IQTQFCIATAL battery capacity in Ah at 20 h discharge rate total quiescent current quiescent standby power source time capacity de-rating factor total current in alarm state alarm load standby power source time compensation factor for expected battery deterioration.L shall be 1.25 for new batteries and 1.1 for used batteries required toperform for at least 12 months

Appendix F – Battery Capacity TestingBattery Test ProcedureThe procedure shall be as follows:a) Prior to testing, ensure the battery is fully chargedwith the correct charging voltage.b) Set the battery testers to a discharge current of 0.8 C20/1 A (e.g. A 100 Ah battery is tested at 80 A),subtracting the system quiescent current if the test isto be carried out without disconnecting the batteryfrom the system.c) Record the total load current used.d) Where the battery is to be tested without beingdisconnected from the system, isolate the primary(mains) supply just before the commencement of thebattery condition test.

Appendix F – Battery Capacity TestingBattery Test ProcedureThe procedure shall be as follows (cont ):e) Apply the test load for 25 min or until battery terminal voltage falls to theminimum test voltage of 21 V (for a 24 V battery set).NOTE: The battery load tester carries a large current and must beconnected as close as practicable to the battery terminals.f) If the battery terminal voltage does not fall below 21 V during the 25 minperiod record the final test voltage and note as a pass.g) Restore the system to allow the battery to begin to be re-charged.

Report all detectors that indicate they are at the end of themanufacturer’s sensitivity range.

Appendix G – Fire Detector TestingDetector Testing – Beam Type Smoke DetectorsG8 BEAM TYPE SMOKE DETECTORSFUNCTIONAL TEST Test yearly the operation of each linear beam type smokedetector use neutral density light filters of the appropriateobscuration percentages for alarm and beam blockage forfault.NOTE: Where information is not available on theappropriate total obscuration then, for direct beamstypes, a 60% obscuration filter should be used and forreflected beam types a 30% obscuration filter. For faults,greater than 95% obscuration (opaque) should be used.
