IMPORTANT NOTICE
DUST & INSECT CONTAMINATION
All Smoke Alarms and particularly the optical (photoe-
lectric) type are prone to dust and insect ingress which
can cause false alarms.
The latest design, materials and manufacturing tech-
niques have been used in the construction of our Alarms
to minimize 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 Smoke 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 cham-
ber causing the alarm to sound. If this happens the
alarm must be returned to us for servicing or replace-
ment. 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.
WARNING
D O N O T I N S T A L L T H E A C T U A L
SMOKE ALARM IN NEW OR RENO-
VATED BUILDINGS UNTIL ALL WORK
IS COMPLETED (INCLUDING FLOOR
COVERINGS) AND BUILDING HAS
BEEN FULLY CLEANED.
(Excessive dust & debris from building work
can contaminate the smoke chamber and
cause problems).
An installed smoke alarm must be removed or cov-
ered fully (with a plastic bag or similar) before reno-
vations begin.
