Carbon monoxide is a dangerous, poisonous gas that
kills hundreds of people each year and injures many
more. It is often referred to as the silent killer because it
has no odour or taste and cannot be seen. Like oxygen,
CO enters the body through the lungs during the normal
breathing process. It competes with oxygen by replacing
it in the red blood cells, thereby reducing the flow of
oxygen to the heart, brain and other vital organs. In high
concentrations, CO can kill in minutes.
Many cases of reported carbon monoxide poisoning
indicate that while victims are aware they are not
feeling well, they become disorientated and unable to
save themselves by either exiting the building or calling
for assistance. Exposure during sleep is particularly
dangerous because the victim usually does not wake up.
Symptoms of CO poisoning
The following symptoms may be related to CO poisoning
which all household members should be made aware of:
• Mild Exposure: Slight headache, nausea, vomiting,
fatigue (often described as ‘flu-like’ symptoms).
• Medium Exposure: Severe throbbing headache,
drowsiness, confusion, fast heart rate.
• Extreme Exposure: Unconsciousness, convulsions,
cardiorespiratory failure, death.
Your CO detector monitors the level of CO as parts
per million (ppm) in the atmosphere surrounding the
The maximum allowable concentration for
continuous exposure for healthy adults in any 8
hour period, as recommended by the Occupational
Safety and Health Administration (OSHA).
200ppm Slight headache, fatigue, dizziness, nausea after
2 - 3 hours.
400ppm Frontal headaches within 1 - 2 hours, life
threatening after 3 hours.
800ppm Dizziness, nausea and convulsions within 45
minutes. Unconsciousness within 2 hours.
Death within 2 - 3 hours.
Should you suspect CO may be affecting you or your
family, open the doors and windows of your property
to ventilate, turn off your appliances and evacuate
the premises. At this time the authorities should be
contacted to locate the source of the carbon monoxide
before re-entering the building. Medical attention
should be sought for anyone suffering the effects of CO
Common sources of CO
• Oil and gas boilers
• Portable generators
• Oil or solid fuel cookers
• Gas or paraffin heaters
• Clogged chimneys
• Wood or gas fireplaces
• Cigarette smoke
• Gas appliances
• Any fossil fuel burning appliance
WARNING: This carbon monoxide detector is not a
combustible gas detector, nor a smoke detector. Please
install the proper detectors to detect combustible gases,
or smoke.
This CO detector should not be seen as a substitute for
the proper installation, use and maintenance of fuelburning appliances (including appropriate ventilation
and exhaust systems), nor the sweeping of chimneys.
WARNING: Variables relating to your fuel burning
appliances can change at any point eg. the flue or
chimney could suddenly become blocked or damaged,
appliances may stop running correctly or circumstances
in neighbouring properties may change resulting in
the presence of carbon monoxide. For this and other
reasons do not use this carbon monoxide detector on an
intermittent basis, or as a portable detector for trying to
trace one source of the spillage of combustion products
from fuel-burning appliances or from chimneys.
Do not:
• Burn charcoal inside your home, caravan, tent or
• Install, convert or service fuel-burning appliances
without proper knowledge, skill and expertise.
• Use a gas cooker for heating a room.
• Operate unvented gas burning appliances using
paraffin or natural gas in closed rooms.
• O
perate petrol-powered engines indoors or in confined
• Barbecue indoors, or in an attached garage.
• Ignore a safety device when it shuts an appliance off.
• Buy appliances accepted by a recognised testing
• Install appliances according to the manufacturer’s
• Have appliance installations carried out by
professionals (for gas appliances engineers should be
registered on the Gas Safe register).
• Have your appliances checked regularly by a qualified
service engineer.
• Have your chimneys and flues cleaned professionally
every year.
• Make regular visual inspections of all fuel-burning
• Open windows when a fireplace or oil/solid fuel cooker
is in use.
• Only install CO detectors that meet the requirements
of EN 50291-1: 2010+A1:2012 and EN 50291-2: 2010 in
your home
• Be aware of CO poisoning symptoms.
• Educate yourself and your family on the sources
and symptoms of co poisoning and how to use your
carbon monoxide detector.
This CO alarm is suitable for
use in domestic premises
(caravan holiday homes),
caravans, motor caravans and boats.
The following advice is applicable to all intended
applications, there are special instructions at the end of
this section relating to positioning in caravan holiday
homes, caravans, motor caravans and boats.
WARNING: This detector will only indicate the presence
of carbon monoxide gas at the sensor. Carbon monoxide
gas may be present in other areas.
In which room should the detector be installed?
Ideally, an apparatus should be installed in every
room containing a fuel-burning appliance. Additional
apparatus may be installed to ensure that adequate
warning is given for occupants in other rooms, by
locating apparatus in:
• Remote rooms in which the occupant(s) spend
considerable time whilst awake and from which they
may not be able to hear an alarm from apparatus in
another part of the premises, and;
• Every sleeping room.
However, if there is a fuel-burning appliance in more
than one room and the number of apparatus is limited,
the following points should be considered when
deciding where best to put the apparatus:
• Locate the apparatus in a room containing a flueless or
open-flued appliance, and;
• Locate apparatus in a room where the occupant(s)
spend most time.
• If the domestic premises is a bedsit (a single room
serving as both sitting and bedroom) then the
apparatus should be put as far from the cooking
appliances as possible but near to where the person
• If the appliance is in a room not normally used (for
example a boiler room), the apparatus should be put
just outside the room so that the alarm may be heard
more easily. Alternatively, a remote alarm siren may be
connected to a type A apparatus located in a room(s)
containing a fuel-burning appliance.
Where in the room should I place the detector?
Apparatus located in the same room as a fuel-burning
appliance, for both wall and ceiling mounted apparatus
the following applies:
a. The apparatus should be at a horizontal distance of
between 1m and 3m from the potential source.
b. If there is a partition in a room, the apparatus should
be located on the same side of the partition as the
potential source.
c. Carbon monoxide detectors in rooms with sloped
ceilings should be located at the high side of the
In addition to the above the following must be observed if
the apparatus is located on a wall:
a.It should be located close to the ceiling;
b.It should be located at a height greater than the height
of any door or window;
c.It should be at least 150mm from the ceiling.
If the apparatus is located on the ceiling it should be at
least 300mm from any wall and any ceiling obstruction
e.g. light fittings.
Apparatus located in sleeping rooms or located in rooms
remote from the fuel-burning appliance should be located
relatively close to the breathing zone of the occupants.
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
previous advice in this section. If 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 previous advice in this
It is not always possible to find an optimum location
for an apparatus, for example, a small caravan 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 1 – 3 m from
the nearest edge of the potential source.
NOTE: This apparatus should be installed by a competent
person who feels able to install it according to the
Firstly write the installation date on your detector in
the area provided. We recommend that your detector is
installed on the wall.
Drill hole spacing
To mount on a wall or ceiling:
Please ensure that you use the screws provided, as they
were chosen specifically for use with this product. Use the
template provided for guidance on marking hole positions.
Drill holes into the wall. Insert the plastic wall plugs. Screw
in the screws. Ensure screws are protruding from the wall
by 3mm to allow detector to slot onto screws.
To place on a shelf:
The base of the detector has been designed to allow it to
stand freely on a shelf.
WARNING: When placing on a shelf, please adhere to
the same positional recommendations as described on
previous pages.
a Your detector comes complete with an integrated power
pack that will provide power for its entire operational
life. To activate the power pack you need to pull the
disabling tab (see image). This will in turn pull out the
metal disabling clip, which is attached to the end of the
tab, from the disabling socket which is situated on the
underside of the detector. Retain the disabling tab for
future use by taping it to page 27 of this manual.
bWhen the detector is activated the Power LED will begin
to flash green once every minute to indicate that the
detector is receiving power from the power pack and is
fully operational.
cTest the sounder, power pack and circuitry by pressing
and holding the centre of the Test/Reset button briefly
to confirm that the detector is operating properly. The
sounder will sound as soon as the button is pressed,
and the Alarm LED will illuminate red indicating that
the sounder is working and the power pack is providing
power to the unit. This test for the sounder, power pack
and circuitry should be performed on a weekly basis.
This should be continued for the lifetime of the product.
WARNING: Prolonged exposure to the sounder in close
proximity to your ears may damage your hearing.
Under normal operating conditions, the power pack will
last for the lifetime of the product ie. 10 years.
The detector will not protect against the risk of carbon
monoxide poisoning when the power pack has drained.
WARNING: Prolonged exposure to extreme high or low
temperatures may reduce the life of the power pack.
Your CO-9X-10 is portable, making it ideal for taking
with you on holiday. You will need to deactivate your
detector when travelling or even when storing e.g. when
decorating. Fitting is the reverse of removal.
The clip must
remain in the
disabling socket
to keep the power
pack deactivated.
To deactivate the detector the two ends of the metal clip
must be inserted into the corresponding holes in the
disabling socket located on the underside of the detector.
You can ensure that the product is disabled by pressing
the test button - if there is no sound from the sounder then
the clip has been fitted correctly.
NOTE: If the disabling tab is no longer available then the
clip can be replicated by opening out a thin metal paper
clip into a U-shape.
Your detector offers many features which set it apart from
other CO detectors on the market today:
Test/Reset button feature
• Tests the sounder, power pack and circuitry.
• Allows you to test the sensor by introducing a source
of CO into the detector.
• Silences the loud 85dB (at 1 metre (3 feet)) sounder
during an alarm (only for alarms due to levels of CO of
less than 50ppm).
Testing the sounder, power pack and circuitry
Test the sounder, power pack and circuitry by pressing
and releasing the Test/Reset button to confirm that the
detector is operating properly. The sounder should sound
as soon as the button is pressed, and the Alarm LED will
illuminate red indicating that the sounder is working and
the power pack is providing power to the unit. This test
should be performed on a weekly basis.
Testing the sensor
CAUTION: Sensor testing should only be performed by
a responsible adult. This test should only be performed
once a month. Excessive testing will shorten the life of
the power pack.
NOTE: Aerosol CO may be used in order to avoid having
to burn incense sticks.
Read all steps thoroughly before attempting the sensor
Step 1 If the detector is wall or ceiling mounted unhook
the detector from the screws.
Step 2
Cover the sounder vents with one hand. Press
and hold the Test/Reset button down with your
thumb/finger until the Fault LED illuminates
amber and the sounder sounds for a second time
(this should happen after around 5 seconds).
Release the Test/Reset button. Upon releasing the
Test/Reset button the Fault LED will flash amber
once every second. This indicates that the
sampling rate of the detector has increased and
can be tested using a known source of CO.
Step 3 Light an incense stick using a match or lighter.
Be sure to blow out the flame so that the incense
stick is smouldering. Extinguish the lighter, or put
out the match and place it into a dish of water.
Step 4
Turn the detector on its side so that the vents on
the right hand side of the detector are pointing
downwards. Hold the burning incense stick
15 cm (6 inches) below the detector, so that the
smoke enters the vents on the side of the
detector. An increase in the localised carbon
monoxide level within the sensor to more than
50ppm will cause the sounder to sound for one
cycle of four loud beeps and the Fault LED to
illuminate amber for a short time. This is the end
of the test.
The Fault LED will no longer flash amber and the
detector will go back to normal operating mode
i.e. the Power LED will flash green once every
minute (it may take up to two minutes of
exposure for the localised level of carbon
monoxide within the sensor to reach over
50ppm). Now move the source of CO away from
the detector as the test is finished.
Step 5 After step 4, put out the incense stick by placing
it into a dish of water. Ensure that all flames
have been extinguished.
NOTE: If the localised carbon monoxide level within the
sensor does not reach 50ppm during the test, the sensor
test will stop automatically after 3 minutes.
The higher the concentration of carbon monoxide detected
by the detector, the quicker it will respond. When sufficient
carbon monoxide is detected a loud audible signal (85 dB
at 1m (3 feet)) will be emitted and the Alarm LED will flash
red once every second.
The alarm will sound:
• Between 60 and 90 minutes when exposed to 50ppm
of CO.
• Between 10 and 40 minutes when exposed to 100ppm
of CO.
• Within 3 minutes when exposed to 300ppm or more
of CO.
Fault / low power pack signal:
The unit continuously checks the settings of its sensor and
circuitry. If any of these settings are found to be incorrect
or if the power pack becomes low then the detector will
emit a single chirp once per minute and the Fault LED will
flash amber once per minute for up to 30 days.
End of life signal: This unit incorporates an “end of life”
signal. This means that 10 years after activation, the unit
will emit a single chirp once per minute and the fault LED
will flash amber once per minute for up to 30 days.
IMPORTANT: This does NOT mean that the detector has
detected carbon monoxide.
If the product is still within warranty then contact Technical
Support. If the product is no longer in warranty replace
IMPORTANT: The selected power pack was chosen
to provide power beyond the lifetime of the product, in
particular the sensor (under normal operating conditions).
The sensor life is ten years. For this reason, the detector
should be replaced after ten years from the date of
Your detector will alert you to potentially hazardous CO
concentrations in your home when maintained properly.
To maintain your detector in proper working order, and
to ensure that the sensor will last for the lifetime of the
product, it is recommended that you:
• Test the sounder, power pack and circuitry of your
detector at least once per week by pressing the Test/
Reset button briefly.
• Perform the sensor test monthly.
• Keep the detector free of dust by gently vacuuming the
case with a soft brush attachment every 3 months.
To prevent the possibility of contaminating the sensor in
your detector and thus affecting its reliability:
• Never use cleaning solutions on your detector. Simply
wipe with a slightly damp cloth.
• Do not paint the detector.
• Do not spray aerosols on or near the detector.
• Do not use any solvent based products near the
• If installing in a caravan or boat there maybe other
substances present, that may not normally be found
in the home, that could effect the reliability of the CO
alarm. Avoid using the following in close proximity to
the alarm; oils, cleaning fluids, polishes, paints and
• Move the detector to a safe location and store in
a plastic bag before painting, wall papering, or
performing any other activities using substances that
emit strong fumes. Remember to remove it from the
bag and replace the detector when these activities are
Failure of any test should be reported to the Technical
Support team.
Do not attempt to repair your CO detector. Do not remove
any screws or open the main casing of your detector.
Any attempt to do so may cause malfunction and will
invalidate the warranty.
WARNING: A loud alarm is a warning that unusually
high and potentially lethal levels of carbon monoxide are
present. Never ignore this alarm, further exposure can be
fatal. Immediately check residents for symptoms of carbon
monoxide poisoning, and contact the proper authorities to
resolve all CO problems. NEVER IGNORE ANY ALARM.
Please carefully review this user manual to ensure that
you know what actions to take in the event of an alarm.
What to do during an alarm
• Keep calm and open the doors and windows to
ventilate the property.
• Stop using all fuel-burning appliances and ensure, if
possible, that they are turned off.
• Evacuate the property leaving the doors and windows
• Ring your gas or other fuel supplier on their
emergency number; keep the number in a prominent
Write your fuel supplier’s emergency number here:
• Do not re-enter the property until the alarm has
stopped. When exposed to fresh air it can take up to 10
minutes for the sensor to clear and the alarm to stop
depending on the level of carbon monoxide detected.
• Get medical help immediately for anyone suffering
the effects of carbon monoxide poisoning (headache,
nausea), and advise that carbon monoxide poisoning
is suspected.
• Do not use the appliances again until they have been
