POSITIONING
This CO alarm is
suitable for use in
domestic premises
as well as caravans, motor caravans and boats.
The following advice, from EN 50292 is
applicable to all intended applications, there
are special instructions at the end of this
section relating to positioning in caravan
holiday homes and boats.
WARNING: This alarm 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 ALARM BE
INSTALLED?
Ideally, an alarm should be installed in every
room containing a fuel-burning appliance and
every sleeping room. Additional alarms may
be installed to ensure that adequate warning
is given for occupants in other rooms, in which
they spend considerable time whilst awake
and from which they may not be able to hear
an alarm in another part of the premises.
CO alarms should also be installed in any room
which a ue passes through, even if the ue is
fully enclosed or concealed.

5
However, if there is a fuel-burning appliance
in more than one room and the number of
alarms is limited, the following points should
be considered when deciding where best to
put the alarm:
• Locate the alarm in a room containing a
ueless or open-ued appliance.
• Locate the alarm 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 alarm should be put as
far from the cooking appliances as possible
and near to where the person sleeps.
• If the appliance is in a room not normally
used (for example a boiler room), the alarm
should be put just outside the room so that
it may be heard more easily.
WHERE IN THE ROOM SHOULD I PLACE
THE ALARM?
For alarms located in the same room as a fuel-
burning appliance (for both wall and ceiling
mounted alarms) the following applies:
• The alarm should be at a horizontal distance of
between 1 m and 3 m from the potential source.
• If there is a partition in a room, the alarm should
be located on the same side of the partition as
the potential source.
• Carbon monoxide alarms in rooms with sloped
ceilings should be located at the high side of
the room.
In addition to the above the following must be
observed if the alarm is located on a wall:
• It should be located close to the ceiling.
• It should be located at a height greater than the
height of any door or window.
• It should be at least 150 mm from the ceiling.
If the alarm is located on the ceiling:
• It should be at least 300 mm from any wall and
any ceiling obstruction e.g. light ttings.
Alarms located in sleeping rooms and in rooms
remote from a 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 admission through air
vents, due to the nearby presence of other
vehicles, engines, generators or barbecues,
however this does not change the basic
guidance on the location of the alarm.
Caravans and boats should be tted with an
alarm in the same room as any combustion
appliance(s), located in accordance with
previous advice in this section. If the caravan
has a single living space which incorporates

6
the sleeping accommodation, it can be
considered to be equivalent to a bedsit,
and a single alarm is sufcient. 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 section. It is not always possible to nd an
optimum location for an alarm, for example, a
small caravan may not have suitable vertical
surfaces available. Nevertheless, when tting
an alarm in such situations, the two most
important considerations when selecting an
appropriate location are:
• Not mounting the alarm directly above a source
of heat or steam.
• Mounting the alarm at a distance of 1-3 m from
the nearest edge of the potential source.
INSTALLATION
ACTIVATING YOUR CO ALARM
Your CO alarm has an integrated battery. To
activate the alarm you need to remove the
disabling clip by pulling it out of the alarm.
Retain the disabling tab for future use.
When the alarm is activated the Power LED
will begin to ash green once every minute to
indicate that the alarm is fully operational. Test
the sounder, battery and circuitry by pressing
and holding the centre of the Test / button
briey to conrm that the alarm is operating
correctly. 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 battery is providing power to
the unit.
INSTALLING YOUR CO ALARM
DO: Ensure this alarm is installed by a
competent person who feels able to install it
according to the instructions.
DO NOT: Tamper with the alarm, for risk of
electric shock or malfunction.
To place on a shelf:
The base of the alarm has been designed to
allow it to stand freely on a shelf.

7
IMPORTANT: When placing on a shelf, please
follow the recommendations for positioning
(See ‘Positioning’).
To mount on a wall:
There are two alternative ways to mount your
CO alarm onto a wall:
1. Using the 2 x screws
Flip down the CO alarm, away from the bracket.
Please ensure that you use the screws provided,
as they were chosen specically for use with
this product. Drill holes into the wall. Insert the
plastic wall plugs. Using a screwdriver push
out the plastic knockouts in the bracket (see
illustration). Using the holes as a guide, drill the
screws through to secure the bracket in place.
2. Using the single point xing option
Flip down the CO alarm, away from the
bracket. Place the nail through the central
hole in the bracket. Carefully hammer the nail
into the wall until the CO alarm is secured into
place.
ALARM TEST
Test the sounder, battery and circuitry by
pressing and releasing the Test / button to
conrm that the alarm is operating properly.
The alarm should sound as soon as the Test
button is pressed, and the Alarm LED will

8
illuminate red indicating that the sounder is
working and the battery is providing power to
the unit. This test should be performed on a
weekly basis.
SLEEP EASY™
Low battery warnings often start at night
or when it may be inconvenient to replace
your alarm. You can silence the audible ‘low
battery’ chirp for a period of eight hours by
pressing the test button. After this period the
audible chirp will start again. This process
can be repeated for a maximum of 10 times.
Your alarm will still detect CO during this time,
however you must replace your alarm within
30 days, as it may have insufcient power to
warn you of a CO leak after this time.
WHAT TO DO IN THE
EVENT OF AN ALARM
WARNING: A loud alarm is a warning that
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 guide 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 open.
• Ring your gas or other fuel supplier on their
emergency number; keep the number in a
prominent place.
• 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.

9
• 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 checked by an expert. In the
case of gas appliances the engineer must
be registered on the Gas Safe register.
WARNING: Alarms conforming to this standard
may not protect people who are at special risk
from carbon monoxide exposure by reason
of age, pregnancy or medical condition. If in
doubt, consult your doctor.
CARBON MONOXIDE:
HOW IT CAN AFFECT YOU
AND YOUR FAMILY
Carbon monoxide is a dangerous, poisonous
gas that kills and injures hundreds of people
each year. 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 ow 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 may not wake up.
SYMPTOMS OF CARBON MONOXIDE (CO)
POISONING:
• Mild Exposure: Slight headache, nausea,
vomiting, fatigue (often described as ‘u-
like’ symptoms).
• Medium Exposure: Severe throbbing
headache, drowsiness, confusion, fast
heart rate.
• Extreme Exposure: Unconsciousness,
convulsions, cardiorespiratory failure,
death.
Your CO alarm monitors the level of CO as
parts per million (ppm) in the atmosphere
surrounding the alarm:
• 35 ppm - 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.

10
• 400ppm - Frontal headaches within 1 - 2
hours, life threatening after three hours.
• 800ppm - Dizziness, nausea and
convulsions within 45 minutes.
Unconsciousness within two hours. Death
within 2 - 3 hours.
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.
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 poisoning.
COMMON SOURCES OF CO:
• Oil and gas boilers
• Portable generators
• Oil or solid fuel cookers
• Gas or parafn heaters
• Barbecues
• Clogged chimneys
• Wood or gas replaces
• Cigarette smoke
• Gas appliances
• Any fossil fuel-burning appliance
WARNING: This carbon monoxide alarm is
not a combustible gas detector, nor a smoke
detector. Please install the proper alarms to
detect combustible gases, or smoke.
This CO alarm should not be seen as a
substitute for the proper installation, use
and maintenance of fuel-burning 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 ue 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 alarm on an intermittent basis, or as
a portable alarm for trying to trace one source
of the spillage of combustion products from
fuel-burning appliances or from chimneys.
