(iv) Check for any sign of contamination such as
cobwebs or dust and clean the Alarm as described
in the “cleaning” section if necessary.
(v) Press the test button for up to 10 seconds to ensure
the sensor chamber, electronics and sounder are
working. A red light on the cover will flash while horn
is sounding. The alarm will stop when the button is
released. Pressing the test button is the best way to
ensure the Alarm is operating correctly. This action
will also clear the memory.
(vi) Interconnected Alarms only - Test the first unit by
pressing the button for 10 seconds. All the units
should alarm within 10 seconds of the first horn
sounding. The red light, on the first unit only, will
flash about once a second. On releasing the button,
the local Alarm will stop sounding immediately and
the remote Alarms will stop sounding approximately
3 seconds later (if testing using RF interconnection
this could take slightly longer). This feature gives an
audible verification that the interconnection is OK.
Check all the other Alarms in the same way.
(vii) Check the functioning of the battery back-up directly
after installation and then at least yearly as follows:
- Turn off the mains power at the distribution board
and check that the green LED is extinguished.
- Press the test button and ensure the horn sounds
loudly for 10 seconds.
- Monitor the Alarm over a 3-minute period for any
fault chirps and red LED fault indicator flashes
(Refer to
Fault Mode
table on what to do if this
occurs).
- Turn the mains supply at the distribution board back
on.
Switching off Mains for long periods
If the premises are regularly being left without mains
power for long periods the Smoke/Heat Alarms should
be removed from their mounting plates to prevent the
batteries becoming fully depleted. (This is sometimes
done with holiday homes which are only occupied in the
Summer).
The Alarms must be re-attached to the mounting plates
when the premises are re-occupied.
WARNING: DO NOT TEST WITH FLAME
This can set fire to the Alarm and damage the house.
We do not recommend testing with smoke or heat as
the results can be misleading unless effective apparatus
is used.
