9. System Maintenance
9.1 Overview
The Fire detectors & Sounders should be tested
weekly and a note made in the system logbook.
1. The operation of manual call points and
detectors should be carried out on a rotational
basis so that all devices are checked at least
once over a 3-month period.
Important:
Ensure that the extinguishing system is
physically disabled by electrical or
mechanical disconnection before
carrying out any tests.
2. To operate a manual call point, use the Test key
provided.
3. To operate a detector, use an approved Test
Smoke.
4. Check the operation of auxiliary items such as
door closers.
5. Re-enable any disabled circuits after
completing the tests.
9.2 Weekly Test Routine
Operate one manual call point and one detector.
These should be on separate zones and the zones
should be varied each week (unless all zones are
always tested).
1. Check that sounder circuits 1 & 2 operate.
2. Remove the test key from all manual call points
and clear all detectors of smoke.
3. Press the Fire Reset button.
4. Operate the test lamps switch and observe that
all indications operate for 5 seconds and the
buzzer sounds.
5. Test one hold, one abort and one auto/manual
switch (if fitted). These should be on separate
SLUs and should be varied each week.
6. Check that operation of the hold switch indicates
a hold condition on the SLU.
7. Check that operation of the abort switch
indicates an abort condition on the SLU.
8. Check that operation of the auto/manual switch
changes the panel from automatic & manual to
manual only operation, as indicated at the SLU.
9. Operate test lamps on each SLU and observe
that all indicators operate.
10. Enter details of the weekly test in the log book.
ENSURE THAT NO DISABLEMENTS REMAIN ON
THE PANEL.
