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

DO NOT INSTALL THE ACTU AL 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.
