11. SERVICE

11.1. Inspections

Conduct the following inspections every 6 months.
1) Inspect detectors for any condition that is likely to adversely affect their operation, such as excessive
deposition of dust or coating of paint.
2) Inspect battery condition for signs of corrosion.
3) Inspect manual call points for clearance and ease of access.
4) Inspect alarm devices for clearance, visibility, and marking.
5) Inspect the documentation to ensure it is available and complete.

11.2. Tests

11.2.1. 6 Monthly Tests
Conduct the following tests every 6 months.
1) Test that an alarm simulated from a detection zone causes the Alarm Condition and all required outputs
(e.g. alarm devices, output relays) activate, including any delayed outputs. Confirm that all required visual
and audible indications and outputs activate at the control and indicating equipment.
2) Test that a Fault Condition occurs for the following events:
a) The removal of a detector from the addressable loop;
b) The failure of the transmission path between the control and indicating equipment and other connected
equipment (eg repeater panel);
c) The failure of the transmission path to networked equipment.
3) Test that disabling a detector in a detection zone causes the control and indicating equipment to enter the
Disabled Condition. Confirm that all required visual and audible indications and outputs activate at the
control and indicating equipment.
Standby Power Source Tests
1) Measure the battery voltage. The battery voltage should be DC (27.5 +± 0.2) V.
2) Disconnect the mains supply and ensure the battery voltage does not fall below DC 27 V.
3) Place the equipment into the Alarm Condition and ensure the battery voltage does not fall below DC 26.5 V.
11.2.2. Annual Tests
Conduct the following tests every 12 months:
1) Test the operation of 20 % of point-type heat detectors using a heat source so that all heat detectors are
tested over 5 years.
2) Test the operation of 50 % of point-type smoke detectors using smoke or suitable aerosols so that all
smoke detectors are tested over 2 years.
3) Test the operation of 50 % of flame detectors using flame or simulated flame so that all flame detectors
are tested over 2 years.
4) Test the operation of 50 % of CO detectors using CO or a suitable gas so that all detectors are tested over
2 years.
5) Test the operation of all manual call points.
6) Test that the audible alarm devices are audible throughout the building and ensure the sound pressure
level meets the requirements of the commissioning report.
7) Test that the light output level from visual alarm devices is no less than the design requirements.
8) Test that the standby power source capacity is equal to or greater than the calculated requirements.
