the sensor chamber, electronics and sounder are
working. A red light on the cover, will flash while horn is
sounding. The alarm will stop when the button is
released. Pressing the test button simulates the effect of
smoke or heat during a real fire and is the best way to
ensure the Alarm is operating correctly.
WARNING: DO NOT TEST WITH FLAME
This can set fire to the Alarm and damage the
house
We do not recommend testing with smoke or heat as the
results can be misleading unless special apparatus is
used.
(iii) Check for any sign of contamination such as
cobwebs or dust and clean the alarm as described in
the "CLEANING YOUR ALARM" section on page 7, if
necessary.
(iv) Interconnected Alarms only· Test the first unit by
I the button for 10 seconds. All the units should
within 10 seconds of the first horn sounding. The
red light on the first unit only will flash about once a
second. Check all the other units similarly.
(v) Check the functioning of the mains battery back-up
directly after installation and then at least yearly as
follows:
Turn off the mains power at the distribution board and
check that the green indicator light is extinguished.
- Press the test button and ensure the horn sounds
loudly for 10 seconds.
Turn on the mains supply at the distribution board only
if the unit passes the above test.
Note: If the mains is disconnected and the battery is
almost depleted the unit will beep every 40 seconds for
at least 30 days.
(vi) Monitor the alarm over a short period of time for any
beeps.
Switching off Mains for long periods
If the premises are regularly being left without mains
power for long periods the smoke/heat alarms should
be removed from their mounting plates to prevent the
batteries becoming fully depleted. (This is sometimes
done with holiday homes which are only occupied in the
Summer).
The alarms must be re-attached to the mounting plates
when the premises are re-occupied.
(Long term storage (over 1 year) with the batteries in a
fully depleted state 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 to ensure that it is satisfactory. If it is depleted
it will give a short beep every 40 seconds.
Models Ei141, Ei144 & Ei146 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 (Ei146) 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
on page 7.
(iii) If the beeps have continued for over 20 minutes
(and the other causes of beeps have been ruled out
- see "TROUBLESHOOTING" section on page 12)
the battery must be replaced.
See "CHANGING THE BATTERY" section on page 4.
Models Ei161 RC, 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
on page 7.
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 on page 11.
Please note: The ionisation alarms (Ei1411161 RC) give
two short beeps about
a
second apart at the end of the
hush period (i. e. about 10 minutes after test/hush button
has been pressed). These two beeps should not be
confused with low battery beeps.
A unit will operate from the mains alone, even with a
fully depleted or a defective battery (and give beeps
every minute), though it may not give sufficient warning
of fire if the mains supply is disconnected for any
reason. If there are any problems get a qualified
electrician to inspect the house wiring and connections
to the alarms.
If there are still problems the unit must be returned for
examination - see "GETTING YOUR ALARM
SERVICED" section on page 11.
6. CLEANING YOUR ALARM
WARNING: Electrical shock hazard. Disconnect the AC
mains at the fuse box or circuit breaker powering the
Alarm before fol/owing the cleaning instructions.
Clean your Alarm regularly, particularly in dusty areas.
Use the narrow nozzle attachment of your vacuum
cleaner to remove dust, insects and cobwebs from the
sides and cover slots where the smoke or heat enters.
To clean the cover, wipe with a damp cloth. Dry cover
thoroughly with a lint free cloth.
WARNING: Do not paint your Alarm.
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 Alarms are to dust and insect ingress which can cause
false alarms or to alarm.
The latest design, materials and manufacturing techniques have
been used in the construction of our Alarms to minimize the
effects 01 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 us 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.
you experience persistent false alarms, in particular locations,
due to contamination of the smoke chamber you could consider
Optical Smoke Alarms (EiI46/166RC) with Ionisation
Smoke Alarms (EiI41/161RC). Ionisation type alarms are less
susceptible to dust than Optical type alarms.
7. NUISANCE ALARMS
When sure that it is just a nuisance alarm, simply pr
the test/hush button briefly on the Alarm to silence
unit for 10 minutes.
If, when the alarm goes off, there is no sign of sm(
heat or noise to indicate that there is a fire, you sh(
get your family into a safe place, before you
~
investigating.
Check the house carefully in case there is a small
smouldering somewhere.
Check whether there is some source of smoke
fumes, for example cooking fumes being drawn past
Smoke Alarm by an extractor.
If there are frequent nuisance/false alarms it may
necessary to re-Iocate the device away from the sOl
of the fumes or replace an Ionisation Alarm with
Optical Alarm. If for some reason the alarm continue
sound without smoke or heat being present (dUE
insect infestation or contamination build-up for exam
the units can be silenced by disconnecting the mi
power and removing the unit - see "ALARM REMOV
section on page 2.
If cleaning the Alarm does not correct the problem it
be returned to the manufacturer for repair
replacement - see "GETTING YOUR ALA
SERVICED" section on page 11 .
Hush Feature
All the Smoke/Heat Alarms have a combined Test/H
Button to help you control nuisance false alarms.
1. To cancel a false alarm, press the Test/Hush Bu
located on the cover. The Alarm will automatically
SVI
to a reduced sensitivity condition (very large level
smoke from a nearby fire will override the Hush on
Smoke Alarms). This condition allows unwanted ala
to be silenced for a period of approximately 10 minu
The unit will flash the red light every 10 seco
(instead of the normal 40 seconds) to indicate
sensitivity is reduced. At the end of the hush pel
the Ionisation Smoke Alarms (Ei1411161RC) and
Heat Alarms (Ei1441164RC)
will
give two sl
beeps.
On interconnected Alarms, pressing the Testlf-:
Button on the one sensing smoke (i.e. the one with
red light flashing every second) will silence aI/ alai
Pressing the Hush Button on any other Alarm will
cancel the alarm.
2. The unit will reset to normal sensitivity at the en
the silenced period. If additional silenced timE
required, simply push the Test/Hush Button again.
