Other than the maintenance and cleaning described in this leaflet, no other
customer servicing of this product is required. Repairs, when needed, must be
performed by the manufacturer.
5.5 Smoke Alarm Automatic Self-Test
The smoke chamber in the Smoke Alarms automatically tests itself every 40
seconds. If the chamber is degraded it will beep without the red light flashing at the
same time. If this happens clean the unit. If the beeping persists and the beep does
not coincide with a red light flash, return the unit for service (see Section 9 - Getting
your Smoke Alarm Serviced).
5.6 Dust & Insect Contamination
All Smoke Alarms and particularly the optical (photoelectric) type are prone to
dust and insect ingress which can cause false alarms. (Heat Alarms are not as
susceptible to dust and contamination as Smoke Alarms, but it is prudent to clean
them periodically).
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. 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.
