Other than the cleaning described above, no other customer
servicing of this product is required. Repairs, when needed,
must be performed by the manufacturer.
All Smoke Alarms are prone to dust and insect ingress which
can cause false alarms or failure to alarm.
The latest design, materials and manufacturing techniques
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 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
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 or fail. If this happens the alarm
must be returned to the manufacturer 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 servicing such units.
If you experience persistant nuisance alarms with the Ei100R3
Ionisation alarm due to cooking fumes you could consider
replacing it with an Optical Alarm (Ei105R3 or Ei105R4) as
they are significantly less susceptible to cooking fumes.
If you experience persistent false alarms, in particular
locations, due to contamination of the optical smoke chamber
(models Ei105R3 & Ei105R4) you could consider replacing
Optical Smoke Alarms (Ei105R3) with Ionisation Smoke
Alarms (Ei100R3). Ionisation type alarms are less susceptible
to dust than Optical type alarms. Heat Alarms are the most
immune to contamination(Ei103R).
NUISANCE ALARMS
Alarms caused by cooking fumes etc. can be readily silenced
by fanning the unit with a newspaper or similiar.
If, when the alarm goes off, there is no sign of smoke, heat or
noise to indicate that there is a fire, you should get your family
into a safe place, before you start investigating.
Check the house carefully in case there is a small fire smould-
ering somewhere.
Check whether there is some source of smoke or fumes, for
example cooking fumes being drawn past the Smoke Alarm
by an extractor.
If there are frequent nuisance/false alarms it may be
necessary to re-locate the device away from the source of the
fumes.
If for some reason an alarm continues to sound without smoke
or heat being present (due to insect infestation or
