Service – routine attention
The owner or occupier of the premises should place the supervision of the system in the
charge of a responsible executive, whose duty it should be to ensure the day to day
operation of the system and to lay down the procedure for dealing with a gas alarm, (see
below) or fault warning. To ensure reliability an agreement should be negotiated for regular
servicing. When a service contract cannot be arranged an employee with suitable
experience of electrical equipment should be trained to deal with the simpler servicing and
instructed not to attempt to exceed the scope of such training.
Liaison should be established with those responsible for maintenance of the building fabric
or redecoration etc. to ensure that their work does not cause a fault or otherwise interfere
with the operation of the alarm installation. Particular attention should be paid to the
Detector Head.
The operating instructions should be kept available with the control unit; all faults, service
tests and routine attention given should be recorded.
DAILY
A check should be made that any fault condition which may be indicated is in fact being
attended to and that all other indicators are normal.
