it is kept clean so that excess dust does not build up. Any insects or cobwebs in the
vicinity of the Smoke Alarm should be promptly removed. In certain circumstances
even with regular cleaning, contamination can build up in the smoke sensing
chamber causing the Alarm to sound. 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 such servicing work.
5.7 Smoke Alarm Replacement
The entire Alarm must be replaced if:-
• The Alarm is installed for over 10 years (check the “replace by” date marked on
the side of the Alarm).
• If the Smoke Alarm is giving a low battery indication - i.e. a short beep with a
simultaneous yellow light flash every 32 seconds. (Note: if it is not convenient to
replace it immediately, pressing the test button will silence the beeps and stop the
yellow LED flashing for 12 hours. This can be repeated as required).
• The Alarm fails to sound the horn loudly when the test button is pressed.
Before the Alarm is safely discarded, remove from the mounting plate (to unpower
the Alarm and to stop low battery beeps).
Do not put the Alarm into a fire.
The Alarm should be disposed in a safe and environmentally sound manner at your
local recycle centre. Contact your local authority for further advice.
