PREVENTION OF FALSE ALARMS DURING ROUTINE TESTING

It is important to ensure that operation during testing does not result in false alarm of fire.
If the fire alarm system is connected to an automatic dialling unit, then transmission should be
prevented (for instance by disconnection) before the routine test is carried out, since under normal
conditions test calls are not permitted. In certain equipment using automatic dialling, it is possible to
prevent transmission of signals by lifting a telephone receiver. Use of this function to inhibit
transmission is deprecated, but where used the inhibited state should be indicated by the use of a notice
on the control equipment.
If transmission of signals to a remote manned central station is prevented during test, a visual
indication of this state should be given at the control equipment. If a link to a remote manned central
station is to be used during the test, then it is essential to notify the centre before undertaking the test,
unless a recognised test procedure is regularly carried out at an agreed time.
The occupants of the premises should be notified of any test of the system that may result in the
sounders being operated.

PREVENTATIVE DAILY MAINTENANCE

A check should be made every day to ascertain the following:-
a) Ensure that the front panel of the Master controller is indicating a normal condition (i.e.
no alarm or faults LED's are lit and the LCD is displaying the correct date and time.
Note: If the panel is not indicating a normal condition, record the condition in the log book
and take any necessary action. Refer section 1.1.
b) Check that any fault recorded on the previous day has received attention.
If any connection to the public fire brigade or other remote manned central station is not continuously
monitored then it should be tested daily in accordance with the suppliers instructions.
Note : on 1 day each week the daily test will be incorporated in the weekly test.
