Open unit by sliding cover up as shown in figure 1. Then
remove the terminal block cover screw.
What to do when the Alarm sounds:
(1) Open the doors and windows to ventilate.
(2) Turn off the appliance where possible and stop using
the appliance.
(The alarm can be silenced immediately by
pushing thetest/hush buttonif the levelis below150ppm CO).
(3) Evacuate the property leaving the doors and windows
open.
(4)
Telephone your gas or other fuel supplier on their emer
-
gency number; keep the number in a prominent place.
(5) Do not re-enter the property until the alarm has
stopped. (If the alarm has been silenced by pressing the
test/hush button, wait at least 5 minutes so the alarm can
check that the CO has cleared).
(6) Get medical help immediately for anyone suffering the
effects of carbon monoxide poisoning (headache, nausea), and advise that carbon monoxide poisoning is suspected.
(7) Do not use the appliance again until it has been
checked by an expert. In the case of gas appliances this
must be a CORGI registered installer.
When the CO Alarm detects abnormal levels of CO
(above 150ppm CO for 30 minutes) the horn sounds and
the red light starts to flash. At higher levels of CO the
alarm will turn on sooner (see table B).
The CO Alarm will automatically reset within about 4 min
-
utes oncethe CO has cleared. Pressingthe test /hush but
ton resets the CO Alarm immediately if it has sensed
about 150ppm CO (the unit cannot be silenced if the level
is about 350ppm CO). If CO is still present the red alarm
light and horn will turn on again after 4 minutes.
WARNING: The CO Alarm is no substitute for keeping
chimneys and flues clear and in good condition, and all of
your appliancesserviced regularly according to themanu
facturer’s instructions.
Do notfit alarm until allbuilding work iscompleted to avoid
contamination.
2.1 What is Carbon Monoxide ?
Congratulations on becoming the owner of an Ei Carbon Mon
oxide Alarm. This will help protectyou andyour householdfrom
the dangerous effects ofcarbon monoxide - the silentkiller (CO
is the chemical symbol).
Many are killed each year, and many more suffer ill health from
carbon monoxide (CO)poisoning. CO isan invisible, odourless,
tasteless and extremelytoxic gas. It is produced by appliances
or vehicles burning fuels, such as coal, oil, natural/bottled gas,
paraffin, wood, petrol, diesel, charcoal etc. CO is absorbed by
red blood cells in the lungs in preference to oxygen - thisresults
in rapid damageto the heart and brain fromoxygen starvation.
High levels of CO in a house can be caused by:
l
Incorrectly or poorly installed fuel-burning appliances.
l
Blocked or cracked chimneys/flues.
l
Blocked vents or draught-proofing which makes areas with
fuel burning appliances or fireplaces airtight.
l
Engines of cars, lawnmowers etc. left running in confined
spaces.
l
Portable paraffin or gas heaters in badly ventilated rooms.
2.2 Symptoms of Carbon Monoxide Poisoning
Most people know that high levels of CO are harmful, however
the period of exposure is also important.
The following symptoms are related to carbon monoxide poi
soning and should be discussed withall membersof the house
hold.
Mild Exposure:
Slight headache,nausea, vomiting, fatigue(of
ten described as “flu-like” symptoms).
Medium Exposure:
Severe throbbing headache, drowsiness,
confusion, fast heart rate.
Extreme Exposure:
Unconsciousness, convulsions, car
-
diorespiratory failure, death.
A high level of CO for a short period (e.g. 350 ppm CO for 30
minutes) willcause the same symptoms, a slightheadache, as a
lower levelfor a longer time (e.g.150 ppm for 90minutes). Table
A shows how exposureto different concentrations of CO gener
-
ally affects people.
Many cases of reported carbon monoxide poisoning indicate
that while victims are aware they are not well, they become so
disorientated theyare unable tosave themselves by eitherleav
ing the building or calling for assistance. Young children and
household pets may be the first affected.
2.3 What happens when your CO Alarm detects Carbon
Monoxide ?
When the Alarm detects dangerous levels of CO, it sounds a
loud alarm and flashes the red alarm light.

Table B shows how the built inmicroprocessor reacts to differ
ent levels of CO gas and exposure time. At higher levels of
CO the alarm turns on sooner. The rate of flashing of the red
light indicates the level of CO.
If your COAlarm sounds follow the instructions onpage 2.
When ventilation is provided by leaving the windows and doors
open, the CO build up may have dissipated by the time help ar
rives and the alarm may have stopped sounding. Although your
problem may appear temporarily solved it is crucial that the
source of theCO is determined and appropriate repairsmade.
NEVER IGNORE THE ALARM.
Pre-Alarm: When the alarm detects over 50ppm CO the red
light flashesevery 5seconds. This helps locate COleaks as the
unit gives an indication straight away. (Without this feature the
CO level would need to be at 150ppm CO for up to 30 minutes
for an indication to be given). Note the Pre-Alarm signal may be
triggered by CO coming for example, from cooking with gas,
from carengines or from nearbybarbecues. This isusually not a
concern unless the Pre-Alarm signal persists for over an hour
and the CO source is unknown.
NOTE:
The CO Alarm may sound if cigarette smoke is blown
into it or aerosols are released nearby.
CO Alarm Memory:
This tells you if the unit has detected CO in your absence and
helps to detect and locate leaks, monitor premises etc.
When thetest button ispressed the horn sounds andthe indica
tor lights flash as follows:-
- Red Lightis Off if no COis detected since reset or power-up.
- Slow Flashing Red Light (every 2 seconds) if 150ppm CO
has been detected since power-up.
- FastFlashing Red Light(every ½ second)if 350ppm CO has
been detected since power-up.
Reset Memory by holding down the test button for over20 sec
onds untilthe red light stopsflashing. Cover the hornwith a cloth
to muffle the alarm.
3.1 Suitable Locations
Ei Electronics recommends that the advice of the Health &
Safety Exectutive (HSE) UK is followed as thisis based on re
search done at the BRE subsequent to the issuing of the BS
7860 : 1996 standard.
The Health & Safety Executive (HSE) UK, give the following
recommendations for rooms where CO alarms should be lo
cated - these are in order of priorty:
- In rooms with flueless or open flued appliances
- In rooms where the occupant spends most time
- In bedrooms
British Standard BS7860:1996 gives the following advice:
Ideally you should have a detector in or near every room that
contains a fuel-burning appliance.
However, ifyou have morethan one appliance, but onlyone de
tector, you shouldtake the following into considerationwhen de
ciding where best to put the detector.
(1) If there is an appliance in the room where you sleep, you
should put the detector in that room.
(2) If there is an appliancein aroom that you use a lot, e.g. a sit
ting room, you should put it in that room.
(3) If you live in a bedsit, put the detector as far away from the
cooking appliancesas possible, butnear to theplace where you
sleep.
(4) If the appliance is in a room not normally used (e.g. a boiler
room), put the detector just outside the room so that you will be
able to hear the alarm more easily.
Ideally you should have a detector in or near every room that
contains a fuel-burning appliance.
3.2 Unsuitable Locations
Do not place the CO Alarm in any of the following areas.
(1) Within 1.85 metres (6 feet) of the appliance.
(2) Outside the building.
(3) In or below a cupboard.
(4) In a damp or humid area.
(5) Directly above a sink or cooker.
(6) Next to a door or window or anywhere that it would be af
-
fected by draughts.
(7) Where it would be obstructed by curtains or furniture.
(8) In an area where the temperature could drop below -5 ° Cor
rise above 40 ° C.
(9) Where dirtor dust could block the sensorand stop it working.
(10) Where it could be easily knocked or damaged, or where it
could be accidently turned off or removed.
(11) In a bathroom or where the CO alarm may be exposed to
water splashes orcondensation (e.g. above an electric kettle).
(12) Near paint, thinners, solvent fumes or air fresheners.
3.3 Installation
The HSE, UKgives more detailed recommendations as follows:
If locating the CO Alarm in a room with an appliance:
- the alarm should be located between 1m and 3m horizontally
from the appliance. (To comply with both BS & HSE advice lo
-
cate between 1.85 and 3.0m from appliance).
- the alarm should be located preferably on the ceiling. Ceiling
mounted detectors should be at least 300mm from any wall.
- if placed on a wall the CO Alarmshould beas high as possible
(higher than doors and windows) but not within 150mm of the
ceiling.

Pre-Alarm
- the alarm should be located at a level similar to the breathing
zone of the occupant (typically in the living roomsat 1.5to 2.0m
above floor level and in bedrooms at the height of the bed).
The BS 7860 : 1996 standard recommends that the CO Alarm
should beat least 1.5 metres (5ft) above floor level. (seefig.3A)
and also the detector should be at least 1.85 metres (6 ft) from
the appliance.
Warnings:
(1) The CO alarm should be installed by a qualified electrican in
accordance with the IEE wiring regulations (BS 7671). Fail
ure to install this alarm correctly may expose the user to
shock or fire hazards.
(2) Do not use the CO Alarm on an intermittent basis, or as a
portable detector for the spillage of combustion products
from fuel-burning appliances or chimneys.
Precaution: Do not installthe actualalarm itself in new or reno
-
vated buildings until all work is completed, including painting,
and the building has been fully cleaned. Wiring can be installed
when appropriate. (Excessive fumes from paints, solvents,
cleaning agents etc. may damage the sensor).
Procedure:
1. Select a location complying with the above advice.
2. Disconnect theAC mains supply from the circuit to be used.
3. Slide off the cover as shown in figure 1. Press gently in the
centre to release the catches before sliding upwards.
4. Removethe terminal cover screw and expose the connecting
terminals.
5. (a) If the wires are coming directly out from the ceiling/wall lo
-
cate the wire entry slot over thewire andmark the two screw lo
cations. Screw the unit to the ceiling/wall (ensure screws do not
penetrate buried wires. The unit can also be screwed on to a
standard recessed junction box if required. Seal the wire exit
holes to prevent air draughts preventing the carbon monoxide
from reaching the sensor.
(b) If surface wiring is being used bring the wiring in from either
of thevertical sides orthe bottom asshown in figure4. Note sur
face wiringcannot be brought in fromthe top as it wouldbe in the
way of the cover sliding off and also might allow water to penetrate. Screw the unit to the wall.
6. The Brownwire (terminal 3) must be connected to the house wir
ing coloured red or brown or to a house terminal marked “L”.
The Blue wire (terminal 4) must be connected to the house wiring
coloured black or blue or to a house terminal marked “N”.
The alarm does not need to beearthed, however for convenience a
spare terminal (no. 5) is provided to hold an earth wire if present.
(1) Regularly check that the green mains power light is on - the
unit cannot detect CO if the mains power is not on (if it is off
check circuit breakers, fuses, wiring etc.).
(2) Test the unit weekly by pressing the test/hush button. Hold
the test button for 5 seconds until the horn sounds for over 5
seconds. This will helpto familiarise you and your family with
the distinctiveon-off sound ofthe CO Alarm.This test checks
that the electronics and the horn are working correctly.
(3) If the CO Alarm gives a short beep and the amber fault light
flashes every45 seconds it means theself-checking circuitry
may havedetected a fault. Press and hold the test/ hush but
ton until the hornsounds and it resets the unit. If the beeping
starts again the Alarm is defective.
(4) If the Alarm fails to operate when the test/hush button is
pressed, disconnect the mainssupply atthe distribution fuse
board for 3 minutes, re-connect the mains and try again.
(This procedure resets the microprocessor in the unit).
If the CO Alarm fails any of the above tests it must be replaced
immediately (see section 9“ Getting the CO Alarm Serviced”).
The CO Alarm is fully operational and will provide protection
against a build up of carbon monoxide gas after it is connected
to the mains supply for 2 minutes.
Testing with Carbon Monoxide
It is recommended that the alarm is tested with actual carbon
monoxide annually. Pressing the test button causes the unit to
check for CO 4 seconds later - this is the Fast CO Test Mode.
This eliminates the long waiting normally required e.g. up to 30
minutes at 150ppm CO and up to 6 minutes at 350ppm CO.
The unit can be tested with CO by using one of the kits that co
-
mes withCO either in a glass phial or aerosolcan. Follow the in
-
structions onthe kitbut be sure to pressthe test button to speed
up the CO samplingdirectly after you expose the unit tothe CO.
It is best if possible to inject the CO gas into the gas entry holes
next to the sensor (see figure 1). When it senses the CO it will
give 3 beeps and the red light willflash asper tableB. It then re
-
sets to normal mode. (If the unit fails to respond press test but
-
ton again as gas can take some seconds to enter sensor).
The Fast CO TestMode normally does not activate the memory
function. (Thiscan be checked by pressingthe test button.If the
red light flashes continuously indicating CO was detected, hold
the testbutton for 20seconds until thered light stopsflashing as
the memory resets).

How to distinguish between CO Alarm and Smoke
Alarm warnings
The CO Alarm has a distinctive on-off sound of 3 pulses, fol
lowed by a pause as compared with a typical Smoke Alarm
which has a rapid pulsing sound.
In addition, when yourCO Alarm is sounding the red alarm light
in the centre of the cover will be flashing.
Testing both your CO Alarms and Smoke Alarms weekly will
help you and your family to clearly distinguish between them in
an emergency.
Clean the outside case by occasionally wiping with a clean
damp cloth (disconnect the mains supply at the distribution /
fuse boardfirst). Do not use anycleaning agents, bleaches, de
tergents or polishes, including those in aerosol cans. Avoid
spraying air fresheners, hair spray, paint or other aerosols near
the CO Alarm. Do not place air fresheners near the unit.
Use the narrow nozzle of a vacuum cleaner to remove fluff and
other contamination from the cover slots to ensure CO gas can
reach the sensor.
Caution: Do not paint the CO Alarm.
Remove the CO Alarm when decorating. Do not allow water or
dust to contaminate the alarm (see below).
Warning: Do not open or tamper with the CO Alarm. There are
no user serviceable parts inside. This can damage the unit and
may expose the user to shock or fire hazards.
How to disconnect and remove the alarm:
1. First disconnect the mains supply to the CO Alarm circuit at
the distribution / fuse board.
2. Slide cover up as shown in figure 1.
3. Unscrew the terminal cover screw.
4. Disconnect the wires from the terminal block and make safe,
particularly if the circuit is going to be turned on again after
the CO Alarm is removed.
5. Unscrew from the wall.
(1) The Ei 225E CO Alarm will not work without mains power -
the green power light must be on at all times.
(2) Carbon monoxide must enter the unit for it to be detected.
There may be carbon monoxide in other areas of the house
(e.g. downstairs, in a closed room etc.) but not in the vicinity
of the CO Alarm. Doors, air draughts and obstructions can
prevent the CO reaching the Alarm. For these reasons we
recommend COAlarms are fitted both nearand in bedrooms,
particularly if bedroom doorsare closedat night. Additionally
in rooms where members of the household spend much of
their time, and in rooms with potential sources of CO gas.
(3) The CO Alarm may not be heard. The sound output is loud,
but it may not be heard behind a closed door or if it is too far
away. The Alarm may notwake up somebodywho has taken
alcohol or drugs. The alarm sound may be masked by other
sounds such as a T.V., stereo, traffic noise etc. Fitting CO
Alarms on either side of closed doors will improve their
chance of being heard. This CO Alarm is not designed for
people with impaired hearing.
(4) CO Alarms don’t last indefinitely. CO Alarms are sophisti
cated electronic devices with many parts. Although the
alarm and its component parts have undergone stringent
tests, and are designed to bevery reliable,it is possible that
parts can fail. Therefore, you should test your CO Alarm
weekly. We recommend that the CO Alarm is replaced after
5 years operation. Check the “replace unit by date” on the
outside of the unit.
(5) CO Alarms are not a substitute for life insurance. House-
holders are responsible for their own insurance. The CO
Alarm warnsof increasing CO levels, but we do not guarantee that this will protect everyone from CO poisoning.
(6) CO Alarms arenot suitable asearly warning SmokeAlarms.
Fire produces carbon monoxide, but the response charac
teristics of these CO Alarms are such that they would not
give sufficient warning of fire.
Smoke Alarms must be fitted to give early warning of fire.
(7) The CO Alarm does not detect the presence of natural gas
(methane), bottled gas (propane, butane) or other combus
tible gases. Fit combustion gas alarms to detect these.
(8) WARNING: APPARATUS CONFORMING TO THE BS
7860 : 1996 STANDARD MAY NOT PROTECT PEOPLE
WHO ARE AT SPECIAL RISK FROM CARBON MONOX
IDE EXPOSUREBY REASON OF AGE, PREGNANCY OR
MEDICAL CONDITION. IF IN DOUBT, CONSULT YOUR
MEDICAL PRACTITIONER.
A CARBON MONOXIDE DETECTOR IS NOT A SUBSTI
TUTE FOR A SMOKE ALARM OR A COMBUSTIBLE GAS
DETECTOR.
Follow these guidelines to reduce the risk of carbon monoxide
poisoning.
(1) Know and look out for tell-tale signs that carbon monoxide
may be present. These include:
- The CO Alarm warning of abnormal levels.
- Staining, sootingor discolouration on or aroundappliances.
- A pilot light frequently going out.
- A strange smell when an appliance is working.
- A naked gas flame which is yellow ororange, insteadof the
normal blue.
- Family members (including pets) exhibiting the “flu-like”
symptoms of CO poisoning described above.
If any of these signs are present get the appliance checked out
by an expert before further use. If family members are ill get
medical help.
(2) Choose all appliances and vehicles which burn fossil fuels
such as coal, oil, natural/bottled gas,paraffin, wood, petrol,diesel, charcoal etc. with care, and have them professionally installed and regularly maintained.
(3) These appliances must “breathe in” air to burn the fuelproperly. Know where the air comes from, and ensure vents/air
bricks etc. remain unobstructed (particularly after building
work).
(4) The appliances must also “breathe out” the waste gases (in
cluding the CO) - usually through a flue or chimney. Ensure
chimneys and flues are not blocked or leaking, and get them
checked every year. Check for excessive rust or cracks on ap
pliances and pipework.
(5) Never leave your car, motor bike or lawnmower engine run
ning in the garage with the garage door closed. Never leave the
door from the house to the garage open if the car is running.
(6) Never adjust your own gas pilot lights.
(7) Never use a gas cooker or a barbecue for home heating.
(8) Children should be warned of the dangers of CO poisoning
and instructednever to touch, orinterfere with theCO Alarm. Do
not allow small children to press the test/hush button as they
could be subjected to excessive noise when the unit alarms.
(9) Leaving windows or doors slightly open (even a few inches)
will significantly reduce the risk of high levels of CO occurring.
The high levels of draught-proofing in modern houses reduces
ventilation and allows dangerous gases to build up.
