What to do when the Alarm sounds:
?
(1) Open the doors and windows to ventilate.
READ THIS FIRST
(Cont.)
(2) Turn off the appliance where possible and stop using
the appliance. (The alarm can be silenced immediately by
pushing the test/hushbutton if level is below 150ppm CO).
(3) Evacuate the property leaving the doors and windows
open.
(4) Ring your gas or other fuel supplier on their emergency
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, nau
sea), 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 a few min
?
utes once theCO has cleared.Pressing the 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 due to theincreased danger). If
CO is still present the red alarm light and horn will turn on
again after 5 minutes.
Warning: The COAlarm is no substitute for keeping chim
?
neys and flues clear and in good condition, and all of your
appliances serviced regularly according to the manufac
turer'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
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 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:
diorespiratory failure, death.
-
A high level of CO for a short period (e.g. 350 ppm CO for 30
Unconsciousness, convulsions, car
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.

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 in microcontroller reacts to different
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
NOTE:
into it or aerosols are released nearby.
2.4 CO Alarm Memory (
When the test button is pressed the horn sounds and the indica
tor lights flash as follows:-
- Flashing Green Light if no CO is detected since reset or
power-up.
- Slow Flashing Red Light (every 2 seconds) if about 150ppm
CO has been detected since power-up.
- Fast Flashing Red Light (every ½ second) if about 350ppm
CO has been detected since power-up.
This tells you if the unit has detected CO in your absence and
helps to detect and locate leaks, monitor premises etc.
Reset Memory by holding down the test button for over 20 seconds until the green light flashes (instead of the red). Cover the
horn with a cloth to muffle the loud alarm. Please note: The
memory will be reset when the battery is removed.
The CO Alarm may sound if cigarette smoke is blown

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 issueing of the BS
7860 : 1996 standard.
CO alarms shouldbe located inthe following areas- these arein
order of priorty:
- In rooms with flueless or open flued appliances
- In rooms where the occupant spends most time
- In bedrooms
Figure 1

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 affected by draughts.
(7) Where it would be obstructed, e.g. 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 sensor andstop it working.
(10) Where it could be easily knocked or damaged, or where it
could be accidentally 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, UK gives recommendations as follows:
If locating the CO Alarm in a room with an appliance
- the alarm should be located between 1.85m and 3m horizon
tally from the 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 appliance
- 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).
Once you have selected a suitable location, open the battery
compartment by sliding up the cover as shown in figure 2.
Install the batteries ensuring they are orientated correctly as
shown in the battery box. The green, red & amber lights will immediately flash in sequence to show they are working - this is
normal.
Mark the position of the two mounting holes by using the unit as
a template. Drill two holes using a 6mm drill for the plastic plugs
supplied, (ensure you don’t drill into the house wiring). Screw
the unit to the wall.
Check that the CO Alarm can be heard in all thebedrooms. If not
another CO Alarm should be located nearer the bedrooms.

3.5 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 or tamper with the CO Alarm. There are no user
serviceable parts inside. This can damage the unit.

Testing & Monitoring your CO Alarm
4.
Button Test
It is recommended that you test your CO Alarm after installation
and then once a week to make sure the unit is working. It will
also help you and your family to become familiar with the sound
of the alarm.
Press and hold the test button until the alarm sounds (it may
take up to 5 seconds) and the green or red light flashes. The
alarm will stop sounding shortly after the button is released. If
there is a problem follow the checklist below.
Power On Indicator
Regularly check that the green power light flashes every minute
- the unit cannot work without a good battery properly con
nected.
Low Battery Indicator
If the unit beeps and the green light flashes simultaneously
every minute, then the three batteries are depleted and they
must be replaced. Use only the following Alkaline AA size batteries: Duracell MN1500, Panasonic LR6, GP 15A, Ever Ready
LR6 or Energiser E91. Open cover as shown in figure 3. (See
section 3.4 if the locking rivethas been inserted). Insert the new
batteries with the orientation shown on the base. Button test the
alarm to check the batteries are installed correctly and that they
are not depleted. Slide back on the cover.
(The batteries will usually last over 4 years in standby under normal conditions. An undepleted battery can power a unit in alarm
for over 100 hours. The life will be reduced if the unit regularly
goes into alarm or if it is exposed to excessive temperatures for
long periods).
Amber Fault Indicator
If the unit beeps and the amber light flashes simultaneously
every minute the self-checking circuitry may have detected a
fault. Follow thechecklist to seeif the unit isactually defective.
Checklist in the event of problems
Check there are three batteries installed with the correct orien
tation in the battery compartment.
Remove one battery for 1 minute to reset the microcontroller in
the unit.
If the problem persists replace the batteries.
If none ofthe above solvethe problem the unit is probably defec
tive and must be replaced. See “Getting the CO Alarm Serv
iced”.
9
Testing with Carbon Monoxide
Pressing the test button causes the unit to check for CO every 4
seconds for 3 minutes. Thiseliminates the long waiting normally
required e.g upto 30 minutesat 150ppm CO and up to 6minutes
at 350ppm CO. If necessary the alarm can be tested with Car
bon Monoxide as follows:
Carbon Monoxide is produced by smouldering cigarettes and
incense sticks. Remove the alarm and place in a large sealed
metal container (e.g. Cooking pot). Place a smouldering ciga
rette or incense stick in the pot. Press the test button - the unit
now checks for CO every 4 seconds. Close the lid. The unit
should sense theCO within 60 seconds and give 3loud beeps. It
then resets to normal mode. If the unit does not respond repeat
ensuring there is sufficient smouldering smoke and that it is re
tained in the alarm by the container.
-
The unit can also be tested with CO by using one of the kits that
comes with CO either in a glass or aerosol can. Follow the in
structions onthe kit but be sure to press the test button to speed
up the CO sampling before you expose theunit to theCO. When
it senses the CO it should give 3 beeps. It then resets to normal
mode.
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 detects CO the red light 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.
5.
Maintaining Your CO Alarm
Clean the outside case by occasionally wiping with a clean
damp cloth. Do not use any cleaning agents, bleaches, deter
gents or polishes,including those inaerosol cans. Avoidspray
ing 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 good batteries - the
green power light must flash every minute. If the battery has
been drained the alarm will not give protection. Button test
the alarm onreturn from holidays and other long absences.
(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 alot 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 wake upsomebody 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 indefinately. 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.
(5) The entire CO Alarm must be replaced after 5 years. Check
the “replace by date” on the outside of the unit.
(6) CO Alarms are not a substitute for insurance. Householders
are responsible for their own insurance. The CO Alarm
warns of increasing COlevels, but we do not guarantee that
this will protect everyone from CO poisoning.
(7) CO Alarms are not suitable as early warning Smoke Alarms.
Fires can produce carbon monoxide,but the response char
acteristics 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.
(8) 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, they 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,
diesel, 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, or otherwiseinterfere with the CO
12
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.

ALARM DOES NOT WORK WITH THE TEST BUTTON:
(1) Hold button down firmly for at least 5 seconds.
(2) Check the batteries are correctly connected.
(3) Replace batteries.
ALARM BEEPS EVERY MINUTE:
If the Alarm beeps every minute and green light flashes at the
same time, then the batteries are depleted and must be re
placed. (See recommended batteries specified in the battery
compartment).
If the Alarm beeps every minute and amber lightflashes at the
same time, then the unit is probably defective. Disconnect bat
teries for 1 minute and re-connect. If problem persists, replace
the unit.
ALARM SOUNDS FOR NO APPARENT REASON:
Follow the detailed instructions in section 1. entitled “What to
do when the alarm sounds” (page 2).
(1) Ensure there are no fuel burning appliances in the vicinity
which could beleaking CO gas (e.g. even from nextdoor).
(2) Ensure there are no fumes in the area (e.g. paint, thinners,
hair spray, chemical cleaners aerosol sprays etc).
(3) Ensure there is no outdoor source of COin the vicinity (e.g. a
car with engine running, heavy traffic, heavy air pollution,
barbecue fumes etc).
(4) Press the test/hush button to silence the alarm.
If the unit continues to sound it is possibly defective and should
be replaced (see section 9 “Getting the CO Alarm Serviced”).
