returned to us for servicing or replacement. Contamination is
beyond our control, it is totally unpredictable and is
considered normal wear and tear. For this reason,
contamination is not covered by the guarantee and a charge
is made for all servicing work.
If you experience persistent false alarms, in particular
locations, due to contamination of the smoke chamber you
could consider fitting our ionisation type Smoke Alarm. The
principle of ionisation detection makes it less vulnerable to the
effects of dust or insect contamination.
5.7
End of life
The entire Smoke Alarm must be replaced if:-
(i) The unit is installed for over 10 years (check the
replacement year marked on the unit).
(ii) The unit is giving a short beep every 40 seconds and the
red light flashes at the same time for over 1 hour. (If the unit
beeps without the red light flashing at the same time see
”Cleaning your Smoke Alarm” above).
(iii) The unit fails to sound the horn loudly when the test button
is pressed.
Before the Smoke Alarm is discarded, cut “end of life” red wire
shown in figure 8 with a scissors to stop the low battery beeps
or the possibility of the unit alarming. Perforate the label to
access wire.
Do not put the Smoke Alarm into a fire.
