1.1. Normal Operation
1.1.1. Power Up
Twist off the Alarm from the mounting plate
(see Quick Start Guide). Remove the battery
tab to power the Alarm, the red LED will flash
once followed by one flash of the yellow LED
to indicate that the Alarm has been powered
successfully and is now in standby mode.
1.1.2. Standby
In standby mode there are no active visible or
audible indications which can be intrusive to
the householder. To confirm that the Alarm is
operational perform a weekly button test.
1.1.3. Weekly button test
Press and hold the test button and verify that
the red LED flashes rapidly and the Alarm
ramps up to full sound.
1.1.4. Sensing Fire
As soon as the Alarm senses smoke it will
go into Alarm. The red LED on the Alarm
sensing smoke flashes rapidly to indicate this
is the Alarm sensing smoke / fire. Follow the
instruction in section 3 and evacuate the
building.
1.1.5. Silence False / Nuisance alarm
Occasionally Smoke Alarms can be activated
by phenomena other than fire, e.g. dust,
insects, cooking fumes. Once you are sure it is
a nuisance alarm press the large test button to
silence the Alarm for 10 minutes – the red LED
will then flash every 8 seconds for 10 minutes.

The Alarm will emit a short beep and flash the
Yellow LED when it becomes partially depleted.
Check the date when the Alarm should be
replaced which is given on the sidewall of the
Alarm. When electronic self testing indicates
that the battery is becoming low the Alarm will
beep and the yellow LED will flash at the same
time (about every 48 seconds) to warn the
user. This indicates that the battery or batteries
must be replaced.
1.2.2. Contaminated chamber
If the Alarm sounds without any apparent
smoke being present, press the test button to
silence the Alarm for 10 minutes (as described
in 1.1.5 above). If the Alarm sounds again
it may be contaminated. Pressing the test
button again, within 4 minutes of the Alarm
re-sounding, will get the Alarm to compensate
for chamber contamination. This will normally
resolve the problem.
If the Alarm re-sounds for a third time, the
Alarm is excessively contaminated and must
be replaced. If it is not convenient to replace
it immediately, pressing the test button within
4 minutes of it going into alarm (for the third
time) will silence the Alarm for 8 hours –
however it will give two short beeps (second
apart) every 10 minutes to remind the user it
has been disabled. If the contamination clears
the Alarm will return to normal operation.
(Note: this does not reduce the users fire
protection, as a Smoke Alarm in continuous
alarm due to a fault, is useless and must be
silenced – by taking the Alarm down or as
described here. This procedure has the added
