PREVENTATIVE 6 MONTHLY MAINTENANCE

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 confirm correct operation as
detailed in weekly tests point
d) Check tested device signal strength readings against recorded commissioning levels.
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 fixings and adjust if necessary. Check voltage
(24v/12V), 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 all aerial connections for damage. External aerial connections should be checked
to ensure water ingress has not taken place. A resistance of 4K7 should be seen
between the centre and outer cores of the coax connector located at the control panel
end of the aerial cable.
Any defect should be recorded in the Fire Alarm System log book and appropriate action taken.
