This Carbon Monoxide Detector is NOT
• A substitute for either a smoke alarm or a combustible
gas detector.
•
To be seen as a substitute for the proper servicing of fuel-burning
appliances or the sweeping of chimneys.
• To be used on an intermittent basis, or as a portable detector for
the spillage of combustion products from fuel-burning appliances
or chimneys.
IMPORTANT
• Carbon Monoxide is produced by the incomplete combustion of
fuels such as wood, charcoal, coal, heating oil, paraffin, petrol,
natural gas, propane, butane etc.
• Ideally, it is recommended that a carbon monoxide detector should
be installed in or near to every room that has a fuel burning
appliance such as any gas fires, central heating boiler, room
heaters, water heaters, cookers, grills, etc.
• This detector should only be installed by a competent person.
• Ensure that the detector alarm can be heard by all those who
are intended to hear it.
• This product should not be used if any fault signals are given.
• Seek medical help if it is suspected that a member of the
household is suffering from carbon monoxide poisoning.

Thank you for purchasing this
detector which is designed to
detect the presence of carbon
monoxide. This manual contains
information on the installation
and operation of the gas detector.
The green power light flashes at
approximately 1 minute intervals
to indicate that the detector is
operating correctly. The red alarm
light will flash continuously and
the buzzer will sound if carbon
monoxide is present.
The detector is suitable for use in areas where cooking and heating
appliances burn fuels such as wood, charcoal, coal, coke, oil, petrol,
gas, etc.
Carbon monoxide (CO) is a highly poisonous gas which is released
when fuels are burnt. It is invisible, has no smell and is therefore very
difficult to detect with the human senses. The first warning symptoms
that CO is present in the air are usually headaches and nausea.
Under normal operating conditions, in a room where fuel-burning
appliances are well maintained and correctly ventilated, the amount
of carbon monoxide released into the room by the appliances is not
dangerous. A dangerous quantity of carbon monoxide can occur if
one or more of the following conditions exists:
1. An appliance is faulty or is badly maintained.
2. A flue is partially or totally blocked.
3. A room is not adequately ventilated.
Carbon monoxide binds to the haemoglobin in the blood and reduces
the amount of oxygen being circulated in the body.
200ppm
Slight headaches, tiredness, dizziness, nausea after
2-3 hours.
400ppm
Frontal headache within 1-2 hours, life threatening after
3 hours.
800ppm
Dizziness, nausea and convulsions within 45 minutes.
Unconsciousness with 2 hours. Death within 2-3 hours.
1600ppm
Headache, dizziness and nausea within 20 minutes.
Death within 1 hour.
6400ppm
Headache, dizziness and nausea within 1-2 minutes.
Death within 10-15 minutes.
Carbon monoxide has a similar density to warm air and, to ensure
that the most effective use is made of the detector, it should be fitted
at least 1.5 metres (5 feet)
above the floor level and
at least 1.85
metres (6 feet)
from the appliance.
Do not place the detector in the following areas:
• Outside the building.
• In or below a cupboard.
• In a damp or humid area.
• Directly above a sink or cooker.
• Next to a door or window or anywhere that would be affected
by draughts.
• Where the air flow to the detector would be obstructed by curtains
or furniture.
• Where dirt or dust could collect and block the sensor, and stop
it working.
• In an area where the temperature could drop below -5˚C or rise
to above 40˚C.
• Where it could be easily knocked, damaged, or where it could
be inadvertently removed.
Ideally a detector should be fitted in or near every room that contains
a fuel-burning appliance. However, if there is more than one appliance
but only one detector, the following points should be taken into
consideration when deciding where best to put the detector.
If there is an appliance in the room where people sleep, the detector
should be placed in that room.
If there is an appliance in a room which people use a lot, such
as a sitting room, the detector should be placed in that room.
In a bedsit the detector should be placed as far away from the cooking
appliances as possible, but near to the place where people sleep.
If the appliance is in a room not normally used, such as a boiler room,
the detector should be placed just outside that room so that the alarm
will be heard more easily.
The detector can either be used as a free-standing unit or can be wall
mounted using the fixings provided.
Find a position to install the detector (see“where to put the detector”
and “where not to put the detector”).
Option 1
Special Mounting Pad with Fixing Pin
(supplied)
Place the fixing pin through the mounting pad.
Using a hammer, gently knock the fixing pin
into the wall ensuring that the mounting pad
is not hammered too firmly into the wall.
Option 2
Screw and Rawlplug (NOT supplied)
If the wall is too hard to use the fixing pin,
use a No. 4 round head screw and rawlplug.
Once activated and tested (see “using the detector”), the detector
can be hung on the protruding fixing pin using one of the ‘keyholes’
on the back.

THIS CARBON MONOXIDE DETECTOR 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
MEDICAL PRACTITIONER.
WARNING
This carbon monoxide detector is designed for indoor use
only. Do not expose to rain or moisture. Do not knock or drop
the detector.Do not open or tamper with the detector as this
could cause malfunction.
The detector will not protect against the risk of carbon
monoxide poisoning when the battery has drained.
