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.
