.
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 below if necessary.
Int rconn ct d Alarms
Test the first unit by pressing the button for 10 seconds. All the
detectors should alarm within about 5 seconds of the first horn
sounding and the red light on the first unit only will flash about
once a second. Check all the other units similarly.
Ch cking R charg abl C lls
(Mod ls Ei 151TL, Ei 154TL & Ei 156TL only)
1. When the alarm is beeping
The Alarm automatically monitors the cells every 40 seconds
to ensure they are satisfactory. If a problem is identified it will
give a short beep every 40 seconds. If the unit is giving beeps
then check the following:
(i) Check that the green mains power light is on. If it is off the
Alarm has been powered from the cells and the beeps indi-
cate they are depleted. Re-connect the mains, check fuse, cir-
cuit breakers and wiring. If in doubt contact a qualified electri-
cian. The beeps should cease within 2 hours as the cells
charge up.
(ii) Check that the hush button has not been pressed inadver-
tently (Ei 151TL only). This also causes beeps every 40 sec-
onds for up to 15 minutes. Press the test button to cancel
hush mode beeps.
(iii) The cells may be depleted. The beeps should cease with-
in 2 hours as they charge up. Fully charged, the cells will pro-
vide up to 6 months back-up without mains power.
(iv) On the Optical Smok Alarms only (Ei 155 & Ei 156TL)
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 the Smoke Alarm.
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 are probably defective.
The Smoke Alarm must be returned to the manufacturer for
repair or replacement (see section Getting Your Alarm
Serviced).
2. Manual Testing
2. We recommend that the functioning of the rechargeable
cells (applicable to models Ei 151TL, Ei 154TL & Ei 156TL
only) is checked periodically (at least yearly) as follows:
(i) Ensure that the alarm has been connected to the mains,
green light on, for a least 2 days for the cells to charge.
(ii) Turn off the mains power at the distribution board and
check that the green indicator light is extinguished. Do not
remove the plug from the rear as this will disconnect the cells.
(iii) Press the test button and ensure the horn sounds loudly
for 10 seconds.
(iv) Release the test button and watch it carefully for one
minute:
• The red light behind the test button or on the cover will
flash at least once.
• The unit must not give a beep which indicates the battery
is low.
(v) Turn on the mains supply at the distribution board only if
the unit passes all the above tests.
Not : If the mains is disconnected and the battery is almost
depleted the unit will beep every 40 seconds for at least 72
hours. This is to remind you to re-connect the mains supply.
The unit will operate from the mains alone, even with a fully
depleted or a defective battery, though it may not give suffi-
cient 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
section on Getting Your Alarm Serviced).
CLEANING YOUR ALARM
WARNING: Electrical shock hazard. Disconnect the AC mains
at the fuse box or circuit breaker powering the Alarm before
following 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. If the
contamination around the outer case indicates that the area is
particularly dirty, remove the Alarm from the ceiling (see figure
1234
1). Check that the openings in the black smoke sensing
chamber are not clogged by visually inspecting them through
the large openings around the edges of the Smoke Alarms. If
they are clogged - an extremely rare occurance - the Smoke
Alarm must be replaced.
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 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 contami-
nation. 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 replace-
ment. 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 persistent false alarms, in particular loca-
tions, due to contamination of the smoke chamber you could
consider replacing Optical Smoke Alarms (Ei 156TL, 155)
with Ionisation Smoke Alarms (Ei 151TL, 150). Ionisation
type alarms are less susceptible to dust than Optical type
alarms.
NUISANCE ALARMS
Alarms caused by cooking fumes etc. can be readily silenced
by fanning the unit with a newspaper or similar. On the
Ei151TL, 150 units, simply press the hush button.
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 fam-
ily into a safe place, before you start investigating.
Check the house carefully in case there is a small fire smoul-
dering 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 neces-
sary to re-locate the device away from the source of the
fumes.
If for some reason the alarm continues to sound without
smoke or heat being present (due to insect infestation or con-
tamination build-up for example) the Ei 150, 153 & 155 mod-
els can be silenced by disconnecting the mains power. In the
case of the Ei 151TL, 154TL & 156TL models (with recharge-
able cells) switching off the mains power alone will not silence
the alarm as it will still be powered by the cells. Switch off the
mains, remove the plug from the rear to disconnect the cells
(after removing the Alarm from the ceiling - see figure 1). If
cleaning the Smoke Alarm does not correct the problem it can
be returned to the manufacturer for repair or replacement.
(see below).
Hush F atur
The Smoke Alarms (Ei 150 & 151TL only) have a Hush Button
to help you control nuisance false alarms.
1. To cancel a false alarm, press the Hush Button located on
the lower right- hand corner. The Alarm will automatically
switch to a reduced sensitivity condition (very large levels of
smoke from a nearby fire will override the Hush). This condi-
tion allows unwanted alarms to be silenced for a period of
approximately 10 minutes. Th unit will giv a short b p
v ry 40 s conds during this tim to l t you know th unit
has b n sil nc d.
On interconnected Smoke Alarms, pressing the Hush Button
on the one sensing smoke (i.e. the one with the red light flash-
ing every second) will silence all alarms. Pressing the Hush
Button on any other Smoke Alarm will not cancel the alarm.
2. The unit will reset to normal sensitivity at the end of the
silenced period. If additional silenced time is required, simply
push the Hush Button again.
3. To quickly return to normal non-silenced operation, simply
push the Test Button ; the alarm will sound briefly and return
to its normal sensitivity alarm mode.
4. After installation, your Smoke Alarm may beep approxi-
mately every 40 seconds for 15 minutes. This indicates it is in
the Hush mode. To put it into normal operating mode, push
and hold the Test Button until the alarm sounds.
IMPORTANT SAFEGUARDS
When using household protective devices, basic safety pre-
cautions should always be followed, including those listed
below:
• Please read all instructions.
• Rehearse emergency escape plans so everyone at home knows what
to do in case the alarm sounds. Further information can be obtained
from the Home Office Publication entitled “Smoke Detectors in the
Home” (FB2) or from your local fire prevention officer.
• NOTE: Constant exposure to high or freezing temperatures or high
humidity may reduce the life of the rechargeable cells.
• To maintain sensitivity to smoke, do not paint or cover smoke alarm in
any manner; do not permit any accumulation of cobwebs, dust or
grease.
• If unit has been damaged in any way or does not function properly,do
not attempt a repair. Return Alarm (see - Getting your Alarm Serviced).
• This appliance is only intended for premises having a residential type
environment.
• Smoke / Heat Alarms are not a substitute for insurance. The supplier or
manufacturer is not your insurer.
• The chamber inside the Ionisation (Ei 151TL, 150) Smoke Alarm con-
tains a small amount of radioactive material. Do not tamper with the
chamber. You may safely install and clean the Smoke Alarm following
this leaflet’s instructions.
• Do not dispose of your Alarm in a fire.
• Ionisation Smoke Alarms can be disposed of in normal household rub-
bish, no more than one alarm per dustbin.
PLANNING YOUR ESCAPE ROUTE FOR
WHEN THE ALARM GOES OFF
Use the Smoke / Heat Alarm Test Buttons to familiarize your
family with the Alarm sound and to practice fire drills regular-
ly with all family members. Draw up a floor plan that will show
each member at least 2 escape routes from each room in the
house. Children tend to hide when they don’t know what to
do. Teach children how to escape, open windows, and use roll
up fire ladders and stools without adult help. Make sure they
know what to do if the alarm goes off - see below.
1. Check room doors for heat or
smoke. Do not open a hot door.
Use an alternate escape route.
Close doors behind you as you
leave.
2. If smoke is heavy, crawl out, stay-
ing close to floor. Take short
breaths, if possible, through a wet
cloth or hold your breath. More peo-
ple die from smoke inhalation than
from flames.
3. Get out as fast as you can. Do
not stop for packing. Have a pre-
arranged meeting place outside for
all family members. Check every-
body is there.
4. Call the Fire Brigade from a
neighbour’s house. Remember to
give your name and address.
5. NEVER re-enter a burning house.
Limitations of Smok Alarms
Smoke Alarms have significantly helped to reduce the number
of fire fatalities in countries where they are widely installed.
However independent authorities have stated that they may
be ineffective in some circumstances. There are a number of
reasons for this:
• The Alarms will not work if the mains power is off and in the
case of the Ei 151TL, 154TL and 156TL if the cells are
depleted.
• Smoke / Heat Alarms will not detect fire if sufficient smoke
/ heat does not reach the alarm. Smoke / heat may be pre-
vented from reaching the Alarm if the fire is too far away,
for example, if the fire is on another floor, behind a closed
door, in a chimney, in a wall cavity, or if the prevailing air
draughts carry the smoke away. Installing Smoke / Heat
Alarms on both sides of closed doors and installing more
than one Smoke / Heat Alarm as recommended in this
leaflet very significantly improves the probability of early
detection.
• The Alarm may not be heard.
• A Smoke / Heat Alarm may not wake a person who has
taken drugs or alcohol.
• Smoke / Heat Alarms may not detect every type of fire to
give sufficient early warning. They are particularly ineffec-
tive with: fires caused by smoking in bed, escaping gas,
violent explosions. poor storage of flammable rags and/or
liquids, (for example petrol, paint, spirits etc), overloaded
electrical circuits, arson and children playing with matches.
• Smoke / Heat Alarms don’t last indefinitely. For example if
there is build up of contamination performance will be
impaired, and in the case of the EI 151TL, 154TL or 156TL
the rechargeable cells may eventually become too weak to
function correctly in the event of a mains power failure.

The manufacturer recommends replacement of the Smoke /
Heat Alarms after 10 years as a precaution.

TROUBLESHOOTING
ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units the red
light under the test button or on the cover will flash rapid-
ly only on the unit which is the source of the alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Fan the unit vigourously with a newspaper to disperse
fumes.
(4) If alarm does not stop, switch off mains and remove unit
(see figure 1). (only remove alarm with red light flashing,
the others are probably satisfactory)
ALARMS BEEPS CONTINUOUSLY:
(1) Alarms may be in ‘hush mode’. Press the test button for 10
seconds to reset the unit (Ei 151TL only).
(2) Cells may be flat due to mains failure (Ei 151TL, 154TL,
156TL only). Check the green mains light is on. If not,
check fuse,circuit breakers and wiring connections.
(3) If the above fails to turn on the green light, a fault may
exist. Switch off mains and remove the unit (see figure 1).
(4) If the green mains light is on and the action in (1) above
has not silenced the beeping, a fault may exist. Switch off
mains and remove the unit (see figure 1).
INTERCONNECTED ALARMS DO NOT ALL SOUND:
(1) Hold test button for 10 seconds after first alarm has sound-
ed to ensure signal is transmitted to all units.
(2) Switch off mains and check that live, neutral and intercon-
nect cables have been correctly connected and that the
connections are tight.
IF FREQUENT NUISANCE ALARMS OCCUR:
(1) Close kitchen / bathroom door when in use.
(2) Ensure that the alarm is sited at least 6m away from
sources of fumes.
(3) Contamination from insects, paint or paint fumes may
have occured. Clean the alarm.
(4) If the problem persists, re-siting of the unit should be con-
sidered. Alternatively, replace the unit with an Optical unit,
assuming that the problem is with an Ionisation type
alarm.
