WHAT IS CARBON MONOXIDE
Carbon Monoxide (CO) is an insidious poison that is released
when fuels are burnt. It is a colorless, odorless, tasteless gas and
therefore very difficult to detect with the human senses. CO kills
hundreds of people each year and injures many more. It binds to
the hemoglobin in the blood and reduces the amount of oxygen
being circulated in the body. In high concentrations, CO can kill in
minutes.
CO is produced by the incomplete combustion of fuels such as
wood, charcoal, coal, heating oil, paraffin, petrol, natural gas,
propane, butane etc.
Common Sources of CO:
Attached garages
Oil and Gas furnaces
Wood stoves
Barbecues
Wood and gas fireplaces
Gas appliances
Portable generators
Gas or kerosene heaters
Clogged chimneys
Cigarette smoke
LOCATING THE CO ALARM
Carbon Monoxide alarm is designed to detect the toxic
CO fumes
that result from incomplete combustion, such as those
emitted
from appliances, furnaces, fireplace and auto exhaust.
Ideally, a CO alarm 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 spend considerable time
whilst awake and from which they may not be able 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 CO
alarm is limited, the following points
should be taken into consideration when deciding on the best
location:
An
apparatus should be located in a room containing a flueless
or open-flued appliance.
If there is an appliance in a room where people spend most
time,
an
apparatus should be placed in that room.
If there is an appliance in a room where people sleep,
an
apparatus should be placed in that room.
In a bedsit, the apparatus should be placed as far from the
cooking appliances as
possible
but near to where the person
sleeps.
If the appliance is in a room not normally used, such as boiler
room, the apparatus should be placed just outside the room so
that
the alarm will be heard more easily.
CAUTION
This alarm will only indicate the presence of carbon monoxide
gas at the sensor. Carbon Monoxide gas may be present in
other areas.
This carbon monoxide alarm is designed to detect carbon
monoxide gas from ANY source of combustion. It is NOT
designed to detect smoke, fire or any other gas.
POSITIONING THE CO ALARM
Carbon Monoxide has a similar density to warm air and can be
fitted in various locations.
Apparatus located in the same room as a fuel-burning
appliance:
If the apparatus is located on a wall, it should be located at a
height greater than the height of any door or window but at
least 150 mm from the ceiling. If the apparatus is mounted on a
ceiling, it should be at least 300 mm from any wall.
The apparatus should be at a horizontal distance of between 1
m and 3 m from the potential source.
If there is partition in a room, the apparatus should be located
on the same side of the partition as the potential source.
In rooms with sloped ceilings, the apparatus should be located
at the high side of the room.
Apparatus located in sleeping rooms and in rooms remote
from a fuel burning appliance:
The apparatus should be located relatively close to the
breathing zone of the occupants.
Areas to be avoided include the following:
Situations where the temperature may drop below -10
o
C or
exceed 40
o
C
In a damp or humid area
Any area where high levels of dusty, dirty or greasy emissions
could contaminate or clog the sensor.
Where the air flow to the apparatus would be obstructed by
curtains or furniture.
Next to a door or window or in the path of air discharged from a
furnace / air conditioning vent or ceiling fan.
Outside the building
Directly above a sink or cooker
In or below cupboard
The following conditions can result in transient CO situations
in the home:
Excessive spillage or reverse venting of fuel burning
appliances caused by:
1.)
Outdoor ambient conditions such as wind direction
and/or velocity, including high gusts of wind; heavy
air in the vent pipes (cold/humid air with extended
periods between cycles).
2.)
Negative pressure differential resulting from the use
of exhaust fans.
3.)
Simultaneous operation of several fuel burning
appliances competing for limited internal air.
4.)
Vent pipe connection vibrating loose from clothes
dryers, furnaces, or water heaters.
5.)
Obstructions in or unconventional vent pipe designs
which amplify the above situations.
Extended operation of unvented fuel burning devices
(range, oven, fireplace, etc.).
Temperature inversions which can trap exhaust gases near
the ground.
Car idling in an open or closed attached garage, or near a
home.
WARNING
This carbon monoxide alarm is designed for indoor use only.
Do not expose to rain or moisture. It will not protect against
the risk of carbon monoxide poisoning when the battery has
drained.
Do not open or tamper with the alarm as this could cause
malfunction.
Installation of the apparatus should not be used as a substitute for
proper installation, use and maintain of fuel burning appliances
including appropriate ventilation and exhaust systems.
INSTALLING THE CO ALARM
This CO alarm is powered by a battery and requires no additional wiring.
It can either be free-standing or installed on the wall using the fixings
provided.
Wall mount installation:
Having established the mounting location ensure
that there is no electrical wiring or pipe work in the area adjacent
to the mounting surface.
Mark the two mounting hole locations.
Drill holes in the positions marked.
Insert wall plugs into the drilled holes.
Screw mounting bracket to mounting surface. DO NOT OVER
TIGHTEN.
Insert a 9V battery firmly into battery compartment on the rear of
the detector. NOTE POLARITY OF CONNECTIONS.
NOTE – For the safety of the end user the CO alarm cannot be
fitted without its battery.
Assemble the alarm onto the mounting plate
OPERATING YOUR CO ALARM
Normal Operation
After battery installation, the green LED will flash five times. Then the
unit will enter into the normal operation mode. When no carbon
monoxide is present, the green light will flash approximately once per
minute and is an indication that your alarm is powered and functional.
During normal operation the CO alarm perform a self-check test every
minute.
IMPORTANT: After installation, test your alarm (see the paragraph
“Test your CO alarm”
Alarm Condition
When the apparatus detects dangerous levels of CO gas, it will give an
alarm signal. The red LED will flash and the buzzer will chirp 6 times
simultaneously every second.
After 30 minutes, when the apparatus remains alarming, the red LED will
flash and the buzzer will chirp 6 times simultaneously every minute.
During alarming, the green LED will flash once every 10 seconds.

WARNING
This product may not alarm at low carbon monoxide levels.
Individuals with medical problems may consider using warning
devices which provide audible signals for carbon monoxide
concentrations under 30 PPM.
Low Battery Signal
A fresh battery should last for one year. In case the battery is at the end
of its life, the apparatus will sound a short chirp with a yellow LED flash
simultaneously in every minute. The battery should be replaced
immediately. This low voltage warning will be given for at least 30 days.
