Instruction Manual H450EN

Carbon Monoxide Alarm
User Manual I56-3495-100
EN 50291:2001

Thank you for purchasing this
alarm which is designed to
detect the presence of Carbon
Monoxide. This manual contains
information on the installation
and operation of the Carbon
Monoxide alarm.

The status light ashes green at

approximately 1 minute intervals
to indicate that the unit is
operating correctly. This will
change to a yellow ash
synchronised with chirp if a fault
arises. The red alarm light will ash continuously and the buzzer
will sound if Carbon Monoxide is present.

The unit 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 difcult to detect with the human senses. The
rst 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 ue is partially or totally blocked.

3. A room is not adequately ventilated.

could cause malfunction.

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 alarm
should be installed in or near to every room that has a fuel
burning appliance such as any gas res, central heating
boiler, room heaters, water heaters, cookers, grills, etc.

• This alarm should only be installed by a competent person.

• Ensure that the audible 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.

• If further details are required which do not appear in this

EFFECTS OF CARBON MONOXIDE POISONING

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.

POSITIONING THE ALARM

1. Units located in the same room as a fuel-burning
appliance

• If the unit is located on the wall it should be located at a
height greater than the height of any door or window but at
least 150mm from the ceiling. If the unit is mounted on the
ceiling it should be at least 300mm from any wall.

• The unit should be at a distance of between 1m and 3m
from the potential source.

• If there is a partition in a room, the unit should be located on
the same side of the partition as the potential source.

• In rooms with sloped ceilings, the unit should be located at
the high side of the room.

2. Units located in sleeping rooms and in rooms remote from
a fuel burning appliance

• Units should be located relatively close to the breathing area
of the occupants.

WHERE NOT TO PUT THE ALARM

Do not place the unit in the following areas:

• Outside the building.

• In or below a cupboard.

• In a damp or highly humid area e.g. a bathroom.

• Directly above a sink or cooker.

• Next to a door or window or anywhere that would be

affected draughts, eg, extractor fan or air vent.

• Where the air ow to the unit 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 -10˚C or
rise to above 40˚C.

• Where it could be easily knocked, damaged, or where it

could be inadvertently removed.

• Do not paint the unit or allow the CO gas inlets to become
blocked by dirt, grease or other substances.

IN WHICH ROOM TO PUT THE ALARM

Ideally, an alarm should be fitted in every room that contains
a fuel-burning appliance. However, if there is more than one
appliance and the number of units is limited, the following points
should be taken into consideration when deciding on the best
location:

• If there is an appliance in a room where people sleep, a unit
should be placed in that room.

• A unit should be located in a room containing a flueless or
open-flued appliance.

• If there is an appliance in a room which people use a lot,
such as a sitting room, a unit should be placed in that room.

• In a bedsit, the unit 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 unit should be placed just outside the room
so that the alarm will be heard more easily.

OPERATION OF THE ALARM

Normal Operation

When no Carbon Monoxide is present, the status light will ash green approximately

once every minute.

During normal operation the unit carries out a self-check test every 5 minutes.

Alarm Condition
When the unit detects Carbon Monoxide, it will give the alarm signal continuously. The

red alarm light will ash and the buzzer will sound approximately 5 chirps per second.

When the unit has been in alarm for 30 minutes the full alarm signal will be given
once every minute.

Alarm Signal

The Carbon Monoxide alarm can be distinguished from smoke detector alarms as it

signals C.O. in morse code (approximately 5 chirps per second).

Hush Feature

If required, the audible alarm can be silenced for 5 minutes by pushing the button
marked ‘Test’. The red alarm light will continue to ash 5 times per second.

If Carbon Monoxide is still present after the 5 minute hush period, the audible alarm

will sound.

NOTE: The hush facility will not operate at levels above 350ppm Carbon Monoxide.
At levels below 350ppm the hush facility will only operate once, ie the audible alarm
can only be silenced for one 5 minute period.

Return to Normal Operation

When the Carbon Monoxide gas disperses, the alarm signal will stop. The status light

will ash green approximately once every minute again.

Fault Warning

If a fault is detected the buzzer will sound 2 short chirps every minute. The unit must

then be replaced.

Battery Fault Warning/End of Battery Life

The buzzer will sound 1 short chirp every minute.

NOTE: With normal use the batteries will last for up to 7 years. However, battery life will
be reduced if either a fault occurs with the battery or the unit remains in alarm for long
periods of time. Should the Battery Fault Warning occur please contact your supplier.

GAS EMERGENCY SERVICE

WHAT TO DO WHEN THE ALARM SOUNDS
