5.6 Dust and contamination from insects
Smoke alarms are sensitive to the penetration of dust and insects, which can trigger
false alarms.
Ei Electronics alarms are made using state-of-the-art design expertise, materials and
production methods to minimise the effects of contamination. However, it is impossible
to eliminate the effects of dust and insects completely.
To ensure your alarm has a long service life, you should make sure it is kept clean and
that dust does not accumulate. All insects or cobwebs in the immediate vicinity of the
alarm should be removed immediately.
In certain circumstances, dirt may still collect in the smoke chamber and set off
the alarm even if it is cleaned regularly. If this happens, the smoke alarm must be
serviced or replaced. Ei Electronics has no control over contamination as it cannot be
predicted and comes under normal wear and tear. Therefore the warranty does not
cover contamination.
