Carbon Monoxide Alarm
User Manual I56-3495-101

INTRODUCTION
Thank you for purchasing this
Red
Status Light:
alarm which is designed to
Alarm
Test
Green = Ok
detect the presence of Carbon
Light
Button
Yellow = Fault
Monoxide. This manual contains
information on the installation
and operation of the Carbon
Monoxide alarm.
The status light flashes green at
approximately 1 minute intervals
to indicate that the unit is
operating correctly. This will
change to a yellow flash
synchronised with chirp if a fault
arises. The red alarm light will flash 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.
WHAT IS CARBON MONOXIDE
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.
CAREFULLY READ AND UNDERSTAND THE CONTENTS
OF THIS INSTRUCTION MANUAL BEFORE USING THE
ALARM. RETAIN THE MANUAL IN A SAFE PLACE FOR
FUTURE REFERENCE.
PAY PARTICULAR ATTENTION TO THE SAFETY
WARNINGS. PASS THE MANUAL ONTO ANY
SUBSEQUENT USERS OF THE ALARM.
WARNING
THIS CARBON MONOxIDE ALARM 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.
This Carbon Monoxide Alarm 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.
CAUTION
This Carbon Monoxide alarm is designed for indoor use
only. Do not expose to rain or moisture. Do not knock or
drop the unit. Do not open or tamper with the unit as this
could cause malfunction.
The alarm will not protect against the risk of Carbon
Monoxide poisoning when the battery has drained.
IMPORTANT
Carbon Monoxide is produced by the incomplete
Buzzer
combustion of fuels such as wood, charcoal, coal, heating
oil, paraffin, petrol, natural gas, propane, butane etc.
Gas Inlet
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 fires, 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
manual, contact Honeywell.

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 flow 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.
INSTALLING THE ALARM
The unit can either be free-standing or wall mounted, using the
fixings provided.
WALL MOUNTING INSTALLATION
Find a position to install the unit (see "where to put the alarm"
and "where not to put the alarm").
Mounting Pad
