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 briefly display all icons). Then wait 15 seconds after
connecting the power before button testing.
• The Power light is not illuminated during standby. This light will flash green
when the test button is pressed to indicate that power is present and Alarm is
functioning.
• 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 and holding the test button for a few seconds.
• 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-1 & B-2
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
in section 6. NEVER IGNORE THE ALARM !

2.4 Pre-Alarm
When the Alarm detects over 43 ppm CO the red light flashes in accordance with
Table B-1 & B-2. This helps locate CO leaks as the CO Alarm 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-1 & B-2.
NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols
are released nearby.
2.5 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 CO
Alarm 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.

Please note that the memory will also be reset when the CO Alarm 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.
11

(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.
3.3 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 figure 2).
3.4 If locating the CO Alarm in a bedroom or in rooms remote from a fuel
burning appliance (see figure 3)
• 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.

3a. Additional information on where to place CO Alarms in recreational vehicless
Caravans and boats
Caravans and boats may have additional risks of carbon monoxide ingress through
air vents due to the nearby presence of other vehicles, engines, generators or
barbecues, however this does not change the basic guidance on location of the
Alarm. Caravans and boats should be fitted with an Alarm in the same room as
any combustion appliance(s), located in accordance with section 3. lf the caravan

or boat has a single living space which incorporates the sleeping accommodation,
it can be considered to be equivalent to a bedsit, and a single Alarm is sufficient.
However, any sleeping accommodation which is in a separate room from the
combustion appliance(s) should also contain an Alarm, located in accordance with
3.4.
Choosing locations in caravans and boats
It is not always possible to find an optimum location for an Alarm, for example,
a small caravan or boat may not have suitable vertical surfaces available.
Nevertheless, when fitting an apparatus in such situations, the two most important
considerations when selecting an appropriate location are:
• not mounting the apparatus directly above a source of heat or steam; and
• mounting the apparatus at a distance of 1m - 3m from the nearest edge of the
potential source.
Interfering Substances
- The apparatus should not be exposed to excessive amounts of fumes from petrol,
diesel, solvents, greases, alcohols and organic cleaning fluids.
- The apparatus may respond to brief exhaust gas emissions e.g. during initial
start-up of an appliance or engine.
- Hydrogen acts as an interferent and may give rise to alarms. Hydrogen can arise
from some battery charging activities and also the curing of concrete under
certain circumstances.
Testing with CO
It is recommended that at least once per year that the apparatus is tested with
Carbon Monoxide, particularly in recreational vehicles.

4. Installation
Warning: The Installation of this CO Alarm should not be used as a subsitute
for proper installation, use and maintenance of fuel buring appliances including
appropriate ventilation and exhaust systems.
4.1 Installation Procedure
1. Select a location complying with the advice in ‘Where
to place CO Alarms’ section.
2. Remove the mounting plate from the packaging/
Alarm.
3. Place the mounting plate on the ceiling/wall exactly
where you want to mount the Alarm. With a pencil, mark
the location of the two screw holes.
4. Taking care to avoid any electrical wiring in the ceiling,
drill holes using a 5.0mm drill bit through the centre of
the marked locations. Push the plastic screw anchors
provided into the drilled holes. Screw the mounting plate
to the ceiling/wall. If wall mounting the CO Alarm, the
panel pin may be used as an alternative to the screws,
provided it is suitable for the mounting surface.
5. Alternatively, if desired, the CO Alarm will also free
stand on a flat surface with the mounting plate attached.
6. If using the RadioLINK interconnection, ensure the RF module is fitted correctly
into the base of the Alarm. For further advice on the RadioLINK installation, see
booklet “RadioLINK Module for Battery Powered Carbon Monoxide Alarms”.

7. Carefully line up the Alarm on the base, gently
press home & twist on – see figure 4. (This
connects the batteries). The red, amber & green
lights will immediately flash in sequence to show
they are working. In addition, the icons on the LCD
display on the Display models will briefly light up.
8. Press the Test button (after 15 seconds) to
ensure that the Alarm works (see figure 5).
9. The Power light is not illuminated during
standby. This light will flash green when the test
button is pressed to indicate that power is present
and Alarm is functioning.
10. Install all the other Alarms similarly.
4.2 How to Tamperproof the Alarm
The Alarm can be made resistant to unauthorised removal. Break off the small pillar
on the base as shown in figure 6a. To remove the Alarm from the ceiling it is now
necessary to use a small screwdriver (see figure 6b), to release the catch (push

catch towards the ceiling) and then twist off the Alarm. If necessary it is possible
to further secure or tamperproof the Alarm by using a No.2 or No.4 (2 to 3mm
diameter - not supplied) self tapping screw 6 to 8mm long to firmly lock the Alarm
and its mounting plate together (see figure 7).
5. Monitoring, Testing & Maintenance
Monitoring
The CO Alarm self checks vital functions to ensure that it is operating correctly.
1. Low battery fault – the battery voltage is measured and compared against a
low voltage threshold.
2. Sensor Fault – the sensor is checked for electrical continuity and open circuit.
3. End of Life fault (EOL) – The Alarm is programmed to check when the useful
life of the Alarm has been exceeded.

Low Battery:
When the battery is starting to be depleted the CO Alarm will beep and the Amber
LED will flash every minute.
The low battery beeps can be supressed for 24 hours by pressing the button.
(It is recommended that this is done until either replacement batteries or a
replacement CO Alarm is available so as to maintain protection against CO leaks).
If it is a CO Alarm with a built in battery (i.e. from the Ei208 series) replace the
entire CO Alarm.
Battery Replacement (For Ei207 Models Only):
Check the ‘Replace by’ label on the side wall -
if it has been exceeded replace the entire CO
Alarm. If the Replace by’ label on the side wall
has not been exceeded, remove the Alarm from
the mounting plate, remove the battery cover (see
figure 8) and replace the batteries. Use only the
following Alkaline AAA size batteries: Duracell,
Panasonic, or Energizer.
Insert the new batteries with the orientation shown
on the base. Replace the battery cover and
replace the Alarm back on its mounting plate (this
action automatically switches on the batteries).
Button test the Alarm (after 15 seconds) to check
the batteries are installed correctly and that they
are not depleted.
