The latest design, materials and manufacturing techniques have been used in
the construction of Ei Electronics Alarms to minimise the effects of contamination.
However it is impossible to completely eliminate the effect of dust and insect
contamination, and therefore, to prolong the life of the Alarm you must ensure that
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. If this happens the Smoke Alarm must be
returned 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 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 red light flash every 32 seconds. (Note: for an iSeries Alarm, if it
is not convenient to replace it immediately, pressing the test button will silence
the beeps and stop the red 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.
