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
you have an Ionisation alarm model Ei3100RF / Ei3500RF,
replacing it with an Optical Alarm Ei3105RF often sloves the
problem. The Ei3105RF is less prone to nuisance alarms due
to cooking fumes (e.g. toast, grilling or frying)).
If you installed the smoke alarms as received and did not
house code them, you may be receiving an alarm signal from
a neighbouring system. This can be easily rectified by “house
coding” your alarms (see section 6).
Ei3105RF only
• To cancel a false alarm, press the test/hush button. The
alarm will automatically switch to a reduced sensitivity
condition. This condition allows unwanted alarms to be
silenced for a period of approximately 10 minutes. The red
light will flash every 10 seconds (instead of 40 seconds) to
let you know the unit has been silenced.
• The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required,
simply push the test/hush button again.
Ei3100RF / Ei3500RF only
• If you have a nuisance alarm with an Ei3100RF / Ei3500RF
simply fan the smoke away with a newspaper or similar.
• If the cause of the alarm is not clear, it should be assumed
that it is due to an actual fire and the dwelling should be
evacuated immediately.
If kitchen usage/layout is such that there are an unacceptable
level of nuisance alarms, re-locate the Smoke Alarm further
away where it will be less affected by cooking fumes etc.
7.4 Cleaning your Smoke Alarm
Clean your Smoke Alarm regularly. Use a soft bristle brush or
the brush attachment of your vacuum cleaner to remove dust
and cobwebs from the sides and cover slots where the smoke
enters. Keep cover closed while cleaning. Do not vacuum or
brush inside the Smoke Alarm.
WARNING: Do not paint your Smoke Alarm.
Other than the maintenance and cleaning described in
this leaflet, no other customer servicing of this product is
required. Repairs, when needed, must be performed by the
manufacturer.
7.5 Automatic Self-Test - Ei3105RF only
The smoke chamber automatically tests itself every 40
seconds. If the chamber is degraded it will beep without the
red light flashing at the same time. If this happens clean the
