READ THIS FIRST
(Cont.)
(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 the test/hush button if the level is below 150ppm
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
?
minutes once the CO has cleared. Pressing the test /hush
button 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 appliances servicedregularly according tothe manu
facturer’s instructions.

Carbon Monoxide - The Silent Killer
2.
2.1 What is Carbon Monoxide ?
Congratulations on becoming the owner of an Ei Carbon Mon
oxide Alarm. This will help protect you and your household from
the dangerous effects of carbon monoxide - the silent killer (CO
are the chemical symbols for C
arbon and Oxygen).
Many are killed each year, and many more suffer ill health from
carbon monoxide (CO)poisoning. CO isan invisible, odourless,
tasteless and extremely toxic 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 - this results
in rapid damageto the heart and brain from oxygenstarvation.
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 poisoning and should be discussed with all members of 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) will causethe same symptoms,a slight headache, as a
lower level for a longer time(e.g. 150 ppmfor 90 minutes).Table
A shows how exposure to 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 they are unable tosave themselves by either leav
ing the building or calling for assistance. Young children and
household pets may be the first affected.

Table B shows how the built in microprocessor 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 in
dicates the level of CO.
If your CO Alarm sounds, follow the instructions given at
the top of page 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 will have stopped sounding. Although your
problem may appear temporarily solved, it is crucial that the
source of theCO is determined and appropriate repairs made.
NEVER IGNORE THE ALARM.
Pre-Alarm: When the alarm detects over 50ppm CO the red
light flashesevery 5 seconds. This helps locate CO leaks 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 car engines or from nearby barbecues. Thisis usually not a
concern unless the Pre-Alarm signal persists for over an hour
and the CO source is unknown.
NOTE:
into it or aerosols are released nearby.
The CO Alarm may sound if cigarette smoke is blown
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 the test button is pressed the horn sounds and the indica
tor lights flash as follows:-
- Red Lightis Off ifno CO is detectedsince reset orpower-up.
- Slow Flashing Red Light (every 2 seconds) if 150ppm CO
has been detected since power-up.
- Fast Flashing Red Light (every ½ second) if 350ppm CO has
been detected since power-up.
Reset Memory by holding down the test button for over 20 sec
onds until the red light stops flashing. Cover the horn witha cloth
to muffle the alarm.
Where to place CO Alarms3.
3.1 Suitable Locations
Ei Electronics recommends that the advice of the Health &
Safety Exectutive (HSE) UK is followed as this is based on re
search done at the BRE subsequent to the issuing of the BS
7860 : 1996 standard.

* If they contain or are near a fuel-burning appliance
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, if you have more than one appliance, but only one de
tector, you shouldtake the followinginto consideration when 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 appliance in a room 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 appliances as possible, but near to the place 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.
6
Sitting
Room
(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
*
affected 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 dirt or dust could block the sensor and stop it work
ing.
(10) Where it could be easily knocked or damaged, or where it
could be accidently turned off or removed.
(11) In sockets where the power is likely to be turned off.
(12) In a bathroom or where the CO alarm may be exposed to
water splashes orcondensation (e.g. above an electric kettle).
(13) Near paint, thinners, solvent fumes or air fresheners.
(14) Plugged into extension sockets.
-
3.3 Installation
The HSE (UK), gives 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 Alarm should be as high as possible
(higher than doors and windows) but not within 150mm of the
ceiling.
If locating the CO Alarm in a room remote from the appli
ance:
- the alarm should be located at a level similar to the breathing
zone of the occupant (typically in the living rooms at 1.5 to 2.0m
above floor level and in bedrooms at the height of the bed).

Warnings:
(1) 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.
(2) Do not open (apart from the cover shown in figure 4) 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.
4.
Testing your CO Alarm
(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 plug, circuit breakers, fuses, wiring etc.).
(2) Test the unit weekly by pressing the test/hush button. Hold
the test button until the horn sounds for over 5 seconds. This
will help to familiarise you and your family with the distinctive
on-off sound of the CO Alarm. This test checks that the elec
tronics and the horn are working correctly.
(3) If the CO Alarm gives a short beep and the amber fault light
flashes every 45 seconds it means the self-checking circuitry
may have detected a fault. Press and hold the test / hush but
ton until the horn sounds 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, unplug it for 3 minutes, plug it back in 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 2 minutes after it is
-
connected to the mains supply.
9
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 with CO either in a glass phial or aerosol can. Follow the in
structions onthe kit but be sure to press the test button to speed
up the CO sampling directly after you expose the unit to the CO.
It is best if possible to inject the CO gas into the gas entry holes
next to the sensor (see diagram on front page). When it senses
the CO it will give 3 beeps and the red light will flash as per table
B. It then resets to normal mode. (If the unit fails to respond
press test button again as gas can take some seconds to enter
sensor).
The Fast CO Test Mode normally does not activate the memory
function. (This can be checked by pressing the test button. If the
red light flashes continuously indicating CO was detected, hold
the test button for 20 seconds untilthe red light stops flashing 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, followed by a pause as compared with a typical Smoke Alarm
which has a rapid pulsing sound.
In addition, when your CO Alarm is sounding the red alarm light
in the centre of the cover will be flashing.
Testing both your CO Alarm and Smoke Alarms weekly will help
you and your family to clearly distinguish between them in an
emergency.

damp cloth (unplug unit first). Do not use any cleaning agents,
bleaches, detergents or polishes, including those in aerosol
cans. Avoid spraying air freshners, 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 comtaminate the alarm.

(1) The 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 CO Alarmsare fitted bothnear and inbedrooms,
particularly if bedroom doors are closed at night. Additionally
in rooms where members of the household spend a lot 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 not wakeup somebody who 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 be very 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 unitby date” onthe 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 warns of increasing CO levels, butwe do not guaran
tee that this will protect everyone from CO poisoning.
(6) CO Alarms are notsuitable as early warning Smoke Alarms.
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.

7.
How to Protect your Family
Follow these guidelines to reduce the risk of carbon monoxide
poisoning.
(1) Know and look for tell-tale signs that carbon monoxide may
be present , these include:
- The CO Alarm warning of abnormal levels.
- Staining, sootingor discolouration onor around appliances.
- A pilot light frequently going out.
- A strange smell when an appliance is working.
- A naked gas flame which is yellow or orange instead of the
normal blue.
- Family members (including pets) exhibiting the “flu-like”
symptoms of CO poisoning described in section 2.2 pg 3.
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, die
sel, charcoal etc. with care, and have them professionally in
stalled and regularly maintained.
-
(3) These appliances must “breathe in” air to burn the fuel properly.
Know where the air comes from, and ensure vents/air bricks etc. re
-
main 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 instructed never to touch, unplug or otherwise interfere with
the CO 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.
(10) Install COAlarms in all areas recommended in thisleaflet.
(11) Recognise that CO poisoning may be the cause when fam
ily members suffer from “flu-like” symptoms when at home, but
feel better when they are away for extended periods.
