Smoke and heat detectors

(For further information refer to BS 5839 or equivalent)

Annual test of at least 2% of installed heat detectors by application of a heat source as a check on reliability. Detectors other than heat should be checked for correct operation and sensitivity in accordance with the manufacturer's instruction.

Regularly inspect detectors for damage, unusual accumulations of dirt, heavy

coats of paint and other conditions likely to interfere with the correct operation of the detector.

Operate a device (manual call point or detector) or end of line switch on a zone circuit. Zones should be tested in strict rotation, each zone being tested at least quarterly for a monitored system, and weekly for a non-monitored system. Each time a zone is tested a different trigger device should be used.
