1. Read This First
• Congratulations on becoming the owner of an Ei Carbon Monoxide Alarm. This
will help protect you and your household from the dangerous effects of Carbon
Monoxide- the silent killer.
• The Carbon Monoxide Alarm (CO Alarm) is powered up by carefully rotating it onto
the mounting plate which activates the on/off switch. The indicator lights will
immediately flash in sequence to show they are working. (For the Display models, the
LCD screen will display all icons). Then wait 15 seconds after connecting the power
before button testing.
• Install a CO Alarm in every room that contains a fuel burning appliance, particularly
rooms where people spend a lot of time e.g. bedrooms, kitchens and sitting rooms.
• In rooms with an appliance, install (preferably) on the ceiling, (300mm from walls)
and between 1m to 3m horizontally from appliance. In rooms remote from the
appliance install at ‘head height’, where the light indicators can be seen.
• Test the Alarm weekly by pressing the test button, and check that the alarm sounds.
• Replace Alarm when the “REPLACE UNIT BY” date has been reached. Check the label
on the side of the alarm.
• Do not fit Alarm until all building work is completed to avoid contamination.

2. Carbon Monoxide – The Silent Killer
2.1 What is Carbon Monoxide ?
Many people are killed each year, and many more suffer ill health from Carbon
Monoxide (CO) poisoning. CO is an invisible, odourless, tasteless and extremely toxic
gas. It is produced by appliances and 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 damage to the heart
and brain from oxygen starvation.
High levels of CO in a house can be caused by:
• Incorrectly or poorly installed fuel-burning appliances.
• Blocked or cracked chimneys/flues.
• Blocked vents or draught-proofing which makes areas with fuel burning
appliances or fireplaces airtight.
• Engines of cars, lawnmowers etc. left running in confined spaces.
• Portable paraffin or gas heaters in badly ventilated rooms.
2.2 What happens when your CO Alarm detects Carbon Monoxide ?
When the Alarm detects potentially dangerous levels of CO, it flashes the red alarm
light immediately and then sounds a loud alarm if the CO persists. Table B below shows
how the CO Alarm 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 indicates
the level of CO. If your CO Alarm sounds follow the instructions on page 21. NEVER
IGNORE THE ALARM ! 5

Pre-Alarm: When the Alarm detects over 43 ppm CO the red light flashes in accordance
with Table B. This helps locate CO leaks as the unit gives an indication straight away.
(Without this feature the CO level would need to be at 43 ppm CO for typically 72
minutes for an alarm sound 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. This is usually not a concern, unless the Pre-Alarm signal persists until the
alarm sounds and the CO source is unknown.
The display models will display CO concentrations greater than 10ppm in accordance
with Table B.
NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are
released nearby.
CO ALARM MEMORY
The CO Alarm memory is an important feature of the CO Alarm where even if the house
is unoccupied during an alarm condition it warns the homeowner that the unit has
previously detected CO gas and been in alarm. The memory feature has two operation
modes:
- memory indication for 24 hour period after alarm.
- memory recall on demand
24 hour memory indicators: After alarm, the RED light will flash at different rates
every minute (approx) depending on the level of CO detected - see Table C.
Memory recall on demand: To review the memory status after initial 24 hours, press
and hold the test button, the red led will flash in accordance to Table C. Display models
will show the peak level of CO measured.

Reset Memory: Hold down the test button until the red light stops and the green
light starts flashing. Cover the horn with a cloth to muffle the alarm during this time.
Please note that the memory will also be reset when the unit is switched off.
3. Where to place CO Alarms
3.1 Ideally a Carbon Monoxide Alarm should be installed in:
- Every room containing a fuel burning appliance, and
- Remote rooms where occupants spend a considerable amount of time
- Every bedroom.
However if the number of Carbon Monoxide Alarms to be fitted is limited, the
following points should be considered when deciding where best to fit the alarm(s)
- If there is an appliance in a room where people sleep, place a CO Alarm in
this room
- Locate a CO alarm in a room containing a flueless or open-flued appliance, and
- Locate an alarm in a room where the occupant(s) spend most of their time (e.g.
sitting room)

- In a bedsit, the CO alarm should be placed as far away from the cooking appliance
as possible, but near to where the person sleeps
- If the appliance is in a room not normally used, such as a boiler room, the CO alarm
should be placed just outside the room so that the alarm will be heard more easily.
3.2 Unsuitable Locations
Do not place the CO Alarm in any of the following areas.
(1) In the immediate vicinity of a cooking appliance (keep it at least 1 metre
horizontally from it).
(2) Outside the building.
(3) In an enclosed space (e.g. in or below a cupboard).
(4) In a damp or humid area.
(5) Directly above a sink or cooker.
(6) Next to a door, window, air vent or anywhere that it would be affected by
draughts.
(7) Next to an extractor fan.
(8) Over heat sources such as radiators or hot air vents.
(9) Where it would be obstructed, e.g. by curtains or furniture.
(10) In an area where the temperature could drop below -10°C or rise above 40°C.
(11) Where dirt or dust could block the sensor.
(12) Where it could be easily knocked or damaged, or where it could be accidentally
turned off or removed.
10

(13) In a bathroom or other areas where the CO alarm may be exposed to
water splashes, dripping or condensation (e.g. above an electric kettle).
(14) Near paint, thinners, solvent fumes or air fresheners.
3.31 If locating the CO alarm in a room with a fuel burning appliance
(see figure 1)
• If it is mounted on a wall, it should be located at a height greater than the height of
any door or window but still be at least 150mm from the ceiling.
• If it is mounted on the ceiling it should be at least 300mm from any wall or light
fitting.
• The CO alarm should be a horizontal distance of between 1m and 3m from the
potential CO source.
• If there is a partition in the room, the CO alarm should be located on the same side
of the partition as the potential source.
• In rooms with sloped ceilings, the CO alarm should be located at the high side of
the room (see fig 2).
3.32 If locating the CO alarm in a bedroom or in rooms remote from a fuel
burning appliance (see figure3)
• Mount the CO alarm relatively close to the breathing zone of the occupants.
Whatever position is chosen make sure it is possible to view the three light indicators,
when in the vicinity of the alarm.
WARNING: Do not use the CO Alarm on an intermittent basis, or as a portable detector
for the leakage of combustion products from fuel burning appliances or chimneys.

5. Testing / Monitoring & Maintenance
Testing
Frequent testing of the system is a requirement to ensure its continued and safe
operation. To test the alarm press the hold the test button.
The Green LED will flash and the horn will sound to indicate the alarm is operating
correctly.
Guidelines and best practices for testing are as follows
1. After the system is installed
2. Once weekly thereafter
3. After prolonged absence from the dwelling (.e.g. after holiday period)
4. After repair or servicing of any of the systems elements or household electrical
works.
Silencing (Hush)
When the Alarm sounds, after sensing CO, pressing the test/hush button will
immediately stop the horn (the red light will continue to flash). If CO is still present the
red light and the horn will turn on again after about 4 minutes. The unit can only be
silenced once during a CO incident. At levels > 150ppm CO the unit cannot be silenced.

Monitoring
The Ei207 / 208 series CO alarm will self check (monitor) itself and give a status update
every minute (approx) if there are any problems.
The status of the alarm can also be checked on demand by using the test button. The
table below shows the status response to both the self check and on demand testing.
If the alarms are indicating a fault, pressing the test button will silence the beeps for a
24 hour period. This is for your conveinence and can only be done once.
Maintenance
Clean the outside case by occasionally wiping with a clean damp cloth. Do not use any
cleaning agents, bleaches, detergents 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.

(For Ei208 Models Only) These alarms uses powered for life lithium batteries and are
not replaceable. Check the ‘Replace by’ label on the side wall - if it has been exceeded
replace the entire unit. If the ‘Replace by’ date has not been exceeded, then the Alarm
maybe faulty and needs to be returned to the manufacturer – (See ‘Getting the CO
Alarm Serviced’ section.
For environmentally sound disposal, remove the Alarm from its mounting plate
(for Ei207 models, open the battery door and remove the batteries) and dispose in
accordance with best practice and guidance on WEEE disposal and recycling.
Quick Test with Carbon Monoxide
The Carbon Monoxide Alarm checks for CO gas every
4 seconds and when exposed to the CO gas, the red
light will flash (as per Table B) to confirm that it is
detecting the CO gas.
The Alarm can be tested with carbon monoxide gas
by using one of the kits that comes with the gas
either in a glass phial or aerosol can. Follow the
instructions on the kit.
If a test gas kit is not readily available it is also
possible to gas test the Alarm using a joss stick
or cigarette smoke. To do this remove the Alarm
from its base and slide the power switch to the ON
position (See fig 9). Fill a suitable size plastic bag
with smoke from the joss stick or cigarette. Insert

the Alarm into the smoke filled bag and seal it closed. Within seconds, the red light will
begin to flash (as per Table B) to confirm that the Alarm has detected the CO gas in the
bag.
To check the Alarm sound, momentarily press the test button and within seconds the
horn will sound briefly. Slide the power switch to the OFF position and replace the Alarm
on its mounting plate.
6. What to do when the alarm sounds
(1) Open the doors and windows to ventilate the area (see note).
(2) Turn off all fuel appliances where possible and stop using them. (The Alarm can be
silenced immediately by pushing the test/hush button).
(3) Evacuate the property leaving the doors and windows open.
(4) Get medical help immediately for anyone suffering the effects of Carbon Monoxide
poisoning (headache, nausea), and advise that Carbon Monoxide poisoning is
suspected.
(5) Ring your gas or other fuel supplier on their emergency number. Keep the number
in a prominent place.
(6) 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).
(7) Do not use the fuel appliances again until they have been checked by a registered
installer or equivalent expert.
