Six Monthly Maintenance

Note: When reference is made to ancillary equipment, the actions should be carried out / checked
on all Radio Cluster Communicator units tted on the system and also the Radio Hub were
applicable.
The following checks should be made:-
a) Perform the weekly checks.
b) Check the entries in the log book and carry out any necessary action.
c) Test all call points and 50% of automatic devices and con rm correct operation as detailed in
weekly tests point
d) Check device signal strength readings against the recorded commissioning levels as per
FireCell minimum requirements.
e) Check all fault indicators by simulating a FAULT condition in each zone either:
i) Removing a detector from its base.
ii) Disconnecting the local circuit from an ancillary unit's circuit.
f ) Visually check the condition of the controller and other ancillary equipment for signs of
moisture ingress and other deterioration.
g) Make overall visual examination, test xings and adjust if necessary.
Check voltage (24V, 12V, 6V), test current draw (mA), test stand-by batteries on load. Check all
battery connections. Check all batteries in control panels and ancillary control equipment. The use
of an ACT meter is recommended.
h) The alarm functions of the control and indicating equipment should be checked by the
operation of a detector or call point in each zone. The operation of the alarm sounders and any link
to a remote manned centre should be tested.
i) Ensure that a clear space of at least 750 mm is preserved in all directions below heat and
smoke detectors, and that all manual call points remain unobstructed and conspicuous.
j) Check any remote aerial connections for damage. A resistance of 47K should be seen
between the centre and outer cores of the coax connector located at Radio Hub or Radio Cluster
Communicator end of the aerial cable.
Any defect should be recorded in the Fire Alarm System log book and appropriate action taken.
