The work will be carried out over the course of two or more service visits during each twelve month period. In addition to the above mentioned work, it is recommended that the following work be carried out every year.
a) The switch mechanism of every manual call point should be tested, either by removal of frangible element, insertion of a test key or operation of
the device as it would be operated in the event of fire.
b) All automatic fire detectors and remote indicators should be examined, as far as reasonably practicable, to ensure that they have not been
damaged, painted, or otherwise adversely affected. Thereafter, every detector should be functionally tested.
c) Every heat detector should be functionally tested by means of suitable heat source.
d) Point smoke detectors should be functionally tested by a method that confirms that smoke can enter the detector chamber and produce a fire signal.
e) Optical beam smoke detectors should be functionally tested by introducing signal attenuation between transmitter and receiver.
f) Aspiration fire detection and fire alarm systems should be functionally tested by a method that confirms that smoke can enter the detector camber
and produce a fire signal.
g) Carbon monoxide fire detectors should be functionally tested by a method that confirms carbon monoxide can enter the chamber and produce a fire
h) Flame detectors should be functionally tested by a method that confirms the detector will respond to a suitable frequency of radiation and produce a
fire alarm signal.
i) In fire detection systems that enable analogue values to be determined at the CIE, it should be confirmed that each analogue value is within the
range specified by the manufacturer. These must be recorded and devices with bad values must be rectified.
j) Multi-sensor detectors should be operated by a method confirms that confirms products combustion in the vicinity of the detector can reach the
sensors and that a fire signal can be produced as appropriate.
k) All fire alarm devices should be checked for correct operation. It should be confirmed that visual fire alarm devices are not obstructed from view and
that their lenses are clean.
l) All unmonitored, permanently illuminated filament lamp indicators at CIE should be replaced.
m) Radio signal strengths in radio-linked systems to which clause 27 applies should be checked for adequacy, and results recorded.
n) A visual inspection should be made to confirm that all readily accessible cable fixings are secure and undamaged.
o) The cause and effect program should be checked to establish as being correct by activating at least one cause and observing the operation of
p) The standby power supply capacity should be checked to establish it remains suitable for continued service.
q) All further annual checks and tests recommended by manufacturer of the CIE and other components of the system should be carried out.
