TEST WEEKLY - PRESS THE BUTTON FOR 10 SEC-
ONDS AND A RED LIGHT ON THE COVER SHOULD
FLASH. INTERCONNECTED ALARMS WILL ALSO
SOUND AFTER A FURTHER 5 SECONDS.
CLEAN YOUR ALARM REGULARLY. THIS WILL REDUCE
THE RISK OF FALSE ALARMS.
REMOVE OR COMPLETELY COVER YOUR ALARM
WHEN REDECORATING TO PREVENT DUST OR OTHER
CONTAMINATION DAMAGING THE UNIT.
DO NOT PAINT OR ALLOW PAINT, WATER OR DUST TO
CONTAMINATE YOUR ALARM.
YOUR ALARM IS A MAINS 230V AC ELECTRICAL
APPLIANCE. DO NOT REMOVE THE COVER OR INSERT
ANYTHING INTO THE ALARM.
IF YOUR ALARM SOUNDS FOR NO REASON AND WILL
NOT RESET, SWITCH OFF THE MAINS AND REMOVE BY
RELEASING BASE CLIP & PUSHING COVER BACK. (SEE
FIGURE 1, BELOW).
INSPECTION &TESTING PROCEDURE
After installation and after re-occupation following a holiday etc.
check all your Alarms weekly as follows:
(i) Check that the green mains indicator light is on. (If it is off check
circuit breakers, fuses and wiring etc.) Check the red light on the
cover flashes every 40 seconds.
(ii) Press the test button for up to 10 seconds to ensure 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 ef-
fect of smoke or heat during a real fire and is the best way to en-
sure 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.
Check for any sign of contamination such as cobwebs or dust and
clean the alarm as described below if necessary.
Interconnected alarms
Test the first unit by pressing the button. 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 once a second. Check all the
other units similarly. (Note: Heat alarms signal to other intercon-
nected alarms about 4 seconds after their own horn sounds. Opti-
cal alarms signal within about a second.
Checking Battery Back-up
When 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 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 (EI 146/145) 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 section below.
If the beeps have continued for over 20 minutes (and the other
causes of beeps have been ruled out - see below) the battery
must be replaced.
(iii) Switch off the mains and remove the unit as shown in figure
1a. Remove depleted battery and replace with one of the speci-
fied 9V alkaline batteries. The alarm cannot be replaced on the
mounting plate unless a battery is installed.
After replacing the battery, slide on the mounting plate then
press the test button and ensure horn sounds loudly before you
turn on the mains. If it is satisfactory turn on the mains and check
that the green light comes on. Note: Only use the specified Alka-
line batteries shown on the base label (Duracell MN1604 or
Eveready 522). We recommend that the “use by date” on the
battery should still have at least 2 years to go. Older batteries will
give beeps prematurely.
We recommend that the battery is replaced each year for opti-
mum performance.
Models Ei164 & EI 166 only
(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 indicate
they are depleted. 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.
(ii) The cells may be depleted. The beeps should cease within 2
hours as they charge up. Fully charged, the cells will provide up
to 6 months back-up without mains power.
(iii) On the Optical Smoke Alarms only (EI 166) 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 / Heat Alarm must be returned to the manufacturer for re-
pair or replacement (see section Getting Your Alarm Serviced).
(Please note: The Heat alarms (EI143/144/164) 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.
Caution: Do not tamper with the lithium battery cells or try to re-
place them. Danger of explosion if battery is incorrectly replaced .
2. Manual Testing:
Models: (Ei 144 / 146 / 164 only).
We recommend that the functioning of the mains battery backup
is checked directly after installation and then at least yearly as
follows:
(i) Turn off the mains power at the distribution board and check
that the green indicator light is extinguished.
(ii) 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 de-
pleted the unit will beep every 40 seconds for at least 30 days.
The unit will operate from the mains alone, even with a fully de-
pleted or a defective battery (and give beeps every minute),
though it may not give sufficient warning of fire if the mains sup-
ply is disconnected for any reason. If there are any problems get
a qualified electrician to inspect the house wiring and connec-
tions to the alarms. If there are still problems the unit must be re-
turned for examination (see section on Getting Your Smoke
Alarm Serviced below).
CLEANING YOUR ALARM
WARNING: Electrical shock hazard. Disconnect the AC mains
at the fuse box or circuit breaker powering the Alarm before fol-
lowing 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 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. How-
ever it is impossible to completely eliminate the effect of dust and insect con-
tamination, 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. Con-
tamination 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 there is a nuisance alarm simply press the test/hush button on
the Alarm to silence the unit for 10 minutes.
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 ex-
ample 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 the alarm continues to sound without smoke or
heat being present (due to insect infestation or contamination
build-up for example) the units can be silenced by disconnecting
the mains power and removing the unit (see figure 1). If cleaning
the Alarm does not correct the problem it can be returned to the
manufacturer for repair or replacement (see Getting Your Alarm
Serviced below).
Hush Feature
All the Smoke Alarms have a combined Test/Hush Button to
help you control nuisance false alarms.
1. To cancel a false alarm, press the Test/Hush Button located
on the cover. The Alarm will automatically switch to a reduced
sensitivity condition (very large levels of smoke from a nearby
fire will override the Hush on the smoke alarms). This condition
allows unwanted alarms to be silenced for a period of approxi-
mately 10 minutes.
The unit will flash the red light every 10 seconds (instead of the
normal 40 seconds) to indicate the sensitivity is reduced. At the
end of the hush period the Heat Alarms (EI 144/143) will give
two short beeps.
On interconnected Alarms, pressing the Test/Hush Button on
the one sensing smoke (i.e. the one with the red light flashing
every second) will silence all alarms. Pressing the Hush Button
on any other Alarm will not cancel the alarm.
2. The unit will reset to normal sensitivity at the end of the si-
lenced period. If additional silenced time is required, simply
push the Test/Hush Button again.
When using household protective devices, basic safety precau-
tions 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.
•NOTE: Constant exposure to high or freezing temperatures
or high humidity may reduce the life of the battery.
•To maintain sensitivity to smoke, do not paint or cover
smoke alarm in any manner; do not permit any accumula-
tion of cobwebs, dust or grease.
•If the 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 resi-
dential type environment.
•Smoke / Heat Alarms are not a substitute for insurance. The
supplier or manufacturer is not your insurer.
•
•Do not dispose of your Alarm in a fire.
Use the Smoke / Heat Alarm Test Buttons to familiarize your
family with the Alarm sound and to practice fire drills regularly
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 lad-
ders 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 alter-
nate escape route. Close doors behind
you as you leave.
2. If smoke is heavy, crawl out, staying
close to floor. Take short breaths, if
possible, through a wet cloth or hold
your breath. More people die from
smoke inhalation than from flames.
3. Get out as fast as you can. Do not
stop for packing. Have a prearranged
meeting place outside for all family
members. Check everybody is there.
4. Call the Fire Brigade from a neigh-
bour’s house. Remember to give your
name and address.
5. NEVER re-enter a burning house.
Limitations of Smoke / Heat Alarms
Smoke / Heat Alarms have significantly helped to reduce the
number of fire fatalities in countries where they are widely in-
stalled.
However independent authorities have stated that they may be
ineffective in some circumstances. There are a number of rea-
sons for this:
•The Alarms will not work if the mains power is off and the
back-up battery is depleted. On the EI141/144/146 alarms
the batteries should be replaced annually and when the unit
gives a low battery beep.
•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 / heat away. Installing Smoke/Heat Alarms
on both sides of closed doors and installing more than one
Smoke/Heat Alarm as recommended in the ‘Siting & Instal-
lation 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, vio-
lent explosions, poor storage of flammable rags and/or
liquids, (for example petrol, paint, spirits etc), overloaded
electrical circuits, arson and children playing with matches.
•Fire Authorities (including the Home Office, UK) recom-
mend that both Optical and Ionisation Smoke Alarms should
be fitted for the fastest response to all types of fires.
•Smoke / Heat Alarms don’t last indefinitely. For example if
there is a build up of contamination, performance will be im-
paired.
The manufacturer recommends replacement of the Smoke /
Heat Alarms after 10 years as a precaution.
If your Alarm fails to work after you have carefully read all the in-
structions, checked the unit has been installed correctly, and is
receiving AC power (green light on) contact Customer Assis-
tance at the address given at the end of this leaflet. If it needs to
be returned for repair or replacement put it in a padded box and
send it to “Customer Assistance and Information” at the nearest
address given on the Alarm or in this leaflet. Do not snap on the
mounting plate as this connects the battery and the unit may
beep or alarm in the post. State the nature of the fault, where the
Alarm was purchased and the date of purchase.
EI Electronics Ltd. guarantees this Alarm (excluding the battery on
the EI141/144/146 models) for five years from date of purchase
against any defects that are due to faulty materials or workmanship.
This guarantee only applies to normal conditions of use and service,
and does not include damage resulting from accident, neglect, mis-
use, unauthorised dismantling, or contamination howsoever
caused. This guarantee excludes incidental and consequential
damage. This guarantee does not cover costs associated with the
removal and/or installation of alarms. If this Alarm should become
defective within the guarantee period, it must be returned to EI
Electronics, with proof of purchase, carefully packaged, with the
problem clearly stated. (see “Getting Your Alarm Serviced”) We
shall at our discretion repair or replace the faulty unit.
Do not interfere with the Alarm or attempt to tamper with it. This will
invalidate the guarantee, but more importantly may expose the user
to shock or fire hazards.

4. INTERCONNECTED ALARMS DO NOT ALL SOUND:
(1) Hold test button for 10 seconds after first alarm has sounded to en-
sure signal is transmitted to all units.
(2) Switch off mains and check that live, neutral and interconnect ca-
bles have been correctly connected and that the connections are
tight.

CONT.

1. 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
occurred. Clean the alarm - see page 5.
(4) If the problem persists, resiting of the unit should be consid-
ered.
2. ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On interconnected units, the red
light on the cover will flash rapidly 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) Press the test/hush button to silence the Smoke/Heat Alarm
for 10 minutes.
(4) If alarm does not stop, switch off mains and remove unit (see
figure 1). (Only remove alarm with red light flashing, the oth-
ers are probably satisfactory).
3. LOW BATTERY & OTHER BEEPS:
(On EIi144/146 only)
If the battery is correctly connected and the unit has beeped for
over 20 minutes the battery is probably depleted. Obtain a new
battery, disconnect the mains, then remove the alarm and replace
the depleted battery.
(On Ei164/166 only)
Check the green mains power light is on. If not, check fuse, circuit
breakers and wiring connections. If the green light is off, the lithium
cells will deplete after some months without mains and will need to
be recharged. If the above fails to turn on the green light, a fault
may exist. Switch off mains and remove the unit (see figure 1).
(All Alarms)
(1) If the green mains light is on and replacing battery, recharging
lithium cells or cleaning unit has not stopped beeps, a fault
may exist. Disconnect the mains first and replace the unit
(see figure 1).
(2) The Ionisation units Ei140/161) give two beeps 10 minutes af-
ter the test//hush button is pressed.
(3) If the Optical units Ei 146/145/166) beeps without the red light
flashing at the same time, the chamber is defective. Clean the
chamber.
