(Long term storage (over 1 year) can damage the
batteries such that they will not recharge when the units
are re-connected to the mains supply).
5.1 If the unit is beeping
The Alarm automatically monitors the battery every 40
seconds. If it is depleted it will give a short beep every
40 seconds.
Models Ei141RC, Ei144RC & Ei146RC only
Before replacing the battery, check that the beeps
are not due to one of the following:
(i) battery snaps not connected properly.
(ii) On the Optical Smoke Alarm only (Ei146RC)
if the unit beeps and the red light does not flash at
the same time it indicates a problem with the smoke
chamber - see “CLEANING YOUR ALARM” section.
(iii) If the beeps have continued for over 20 minutes
(and the other causes of beeps have been ruled out
- see “TROUBLESHOOTING” section) the battery
must be replaced.
See “CHANGING THE BATTERY” section.
Models Ei161RC, Ei164RC & Ei166RC only
(i) Check that the green mains power light is on. If
it is off the Alarm is not receiving mains power and
is being powered from its internal back-up cells. The
beeps indicate that they are depleted. The cells are
not replaceable. Re-connect the mains, check fuse,
circuit breakers and wiring. If in doubt contact a
qualified electrician. The beeps should cease within
2 hours as the cells charge up. Fully charged, the
cells will provide up to 6 months back-up without
mains power.
(ii) On the Optical Smoke Alarm only (Ei166RC)
if the unit beeps and the red light does not flash at
the same time it indicates a problem with the smoke
chamber - see “CLEANING YOUR ALARM” section.
If all of the above possible causes of beeps have
been ruled out, but the beeping has still persisted
for over 2 hours with the green light on - the
rechargeable cells may be defective. The Smoke /
Heat Alarm must be returned to the manufacturer for
repair or replacement - see “GETTING YOUR ALARM
SERVICED” section.
