The interval between the maintenance visit on each system should not be greater than 6 months.You could do 100% on 3 of the systems each quarter and carry out the following on the remainder -
c) The records of false alarms should be checked in accordance with 30.2i). The rate of false alarms during
the previous 12 months should be recorded [see 30.2i)]. Action taken in respect of false alarms recorded
should comply with the recommendations of 30.2j).
d) The standby battery should be disconnected and full load alarm should be simulated.
e) Batteries and their connections should be examined and momentarily load tested with the mains
disconnected (other than those within devices such as manual call points, detectors and fire alarm
sounders of a radio-linked system), to ensure that they are in good serviceable condition and not likely
to fail before the next service visit. Vented batteries should be examined to ensure that the specific
gravity of each cell is correct.
f) The fire alarm functions of the control and indicating equipment should be checked by the operation of
at least one detector or manual call point on each circuit. An entry should be made in the log book
indicating which initiating devices have been used for these tests.
g) The operation of the fire alarm devices should be checked.
h) All controls and visual indicators at control and indicating equipment should be checked for correct
operation.
i) The operation of any facility for automatic transmission of alarm signals to an alarm receiving centre
should be checked. Where more than one form of alarm signal can be transmitted (e.g. fire and fault
signals), the correct transmission of each signal should be confirmed.
j) All ancillary functions of the control and indicating equipment should be tested.
k) All fault indicators and their circuits should be checked, where practicable, by simulation of fault
conditions.
l) All printers should be tested to ensure that they operate correctly and that characters are legible.
It should be ensured that all printer consumables are sufficient in quantity or condition to ensure that
the printer can be expected to operate until the time of the next service visit.
m) Radio systems of all types should be serviced in accordance with the recommendations of the
manufacturer.
n) All further checks and tests recommended by the manufacturer of the control and indicating
equipment and other components of the system should be carried out.
o) On completion of the work, any outstanding defects should be reported to the responsible person, the
system log book [see 40.2d)] should be completed and a servicing certificate should be issued.
