WHAT IS CARBON MONOXIDE?
Carbon Monoxide is a colourless, odorless and tasteless poison gas that can be fatal when
inhaled. CO binds to the hemoglobin in the blood and inhibits its capacity to carry oxygen. CO
kills hundreds of people each year and injures many more because it is difficult to detect with the
human senses. In high concentrations, CO can kill in minutes.
SOURCES OF CARBON MONOXIDE?
Inside your home, appliances used for heating and cooking are the most likely source of CO.
Vehicles running in attached garages can also produce dangerous levels of CO. CO can be
produced when burning any fossil fuel, such as gasoline, propane, natural gas, oil and wood. It
can be produced by any fuel-burning appliance that is malfunctioning, improperly installed, or not
ventilated correctly, such as:
• Cars, fires, gas ranges/stoves, gas clothes dryers, water heaters, portable fuel burning space
heaters and generators, fireplaces, wood-burning stoves and certain swimming pool heaters.
• Blocked chimneys or flues, back drafts and changes in air pressure, corroded or disconnected
vent pipes, loose or cracked fire exchangers.
• Vehicles and other combustion engines running in an open or closed garage, attached or near
the home.
• Burning charcoal or fuel in grills and BB s in an enclosed area.
Than you for purchasing a KingShield Carbon Monoxide Alarm
from GreenBroo Electrical. This alarm must be installed by a
competent person, using the following installation instructions.
KEEP THESE INSTRUCTIONS SAFE FOR FUTURE REFERENCE
SAFETY INFORMATION
ACOMN Instr ctions 15.10.13:Layo t 1 29/10/13 12:41 Page 1

The following conditions can result in transient CO situations:
• Excessive spillage or reverse venting of fuel-burning appliances caused by 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).
• Negative pressure resulting from the use of exhaust fans.
• Simultaneous operation of several fuel-burning appliances competing for limited internal air.
• Vent pipe connections vibrating loose from clothes dryers, fires or water heaters.
• Obstructions in, or unconventional vent pipe designs which can amplify the above situations.
• Extended operation of unvented fuel-burning devices (range, oven, fireplaces, etc.).
• Certain household materials such as cleaning fluids, polishes, paints and cooking operations
may affect the reliability of the alarm.
• Vehicle idling in an open or closed garage, or near a home.
To be safe, know the possible sources of CO in your home. Keep fuel-burning appliances and their
chimneys and vents in good working condition. Learn the early symptoms of exposure, and if you
suspect CO poisoning, move outside to fresh air and get emergency help.
Your first line of defence is an annual inspection and regular aintenance of your appliance. Contact a
licensed contractor or call your local utility co pany for assistance.
SYMPTOMS OF CO POISONING
35 ppm The maximum allowable concentration for continuous exposure for
healthy adults in any 8 hour period.
200 ppm Slight headaches, fatigue, dizziness, nausea after 2-3 hours.
400 ppm Frontal headaches within 1-2 hours, life threatening after 3hours.
800 ppm Dizziness, nausea and convulsions within 45 minutes. Unconsciousness
within 2hours and death within 3hours.
1600 ppm Headache, dizziness and nausea within 20 minutes. Death within 1hour.
6400 ppm Headache, dizziness and nausea within 1-2 minutes.
Death in less than 20 minutes
* PPM = parts per illion
The following symptoms related to CO POISONING and are to be discussed with all members of
the household:
Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as “flu-like”
symptoms).
Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure: Unconsciousness, convulsions, cardio respiratory failure, death.
Many cases of reported Carbon Monoxide Poisoning indicates that while victims are aware they
are not well, they become so disoriented they are unable to save themselves by either leaving the
building or calling for assistance. Young children and household pets are typically the first
affected.

Typical Multi-Story or Split Level Home
For minimum protection, you should fit at least one alarm on each floor/level.
Note: For maximum protection an alarm should be fitted in or near every room that contains a
fuel-burning appliance such as any central heating boilers, gas fires, room heaters, water heaters,
cookers, grills etc.
Apparatus located in the same room as a fuel-burning appliance:
If the apparatus is located on a wall:
a) It should be located close to the ceiling;
b) It should be located at a height greater than the height of any door or window
A ceiling mounted apparatus should be at least 300mm from any wall, and for a wall mounted apparatus
it should be at least 150mm from the ceiling.
The apparatus should be at a horizontal distance of between 1M and 3M from the potential source.
If there is a partition in a room, the apparatus 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.
CAUTION: CO alarms can only sense CO that reaches the unit’s sensor. It’s possible that CO may be
present in other areas without reaching the alarm.
This carbon monoxide alarm is designed to detector carbon monoxide gas from ANY source of
combustion. It is NOT designed to detect smoke, fire or any other gas.
Apparatus located in sleeping rooms and in rooms remote from a fuel burning appliance:
Carbon Monoxide has a similar density to warm air and alarms can be fitted in various locations.
Apparatus located in sleeping rooms and in rooms remote from the fuel-burning appliance should
be located relatively close to the breathing zone of the occupants.
Improper location can affect the sensitive electronic components in this alarm. To avoid causing
damage to the unit, to provide optimum performance, and to prevent unnecessary nuisance

100 10-40
300 <3
WARNING: This product may not alarm at low carbon monoxide levels. Individuals with medical
problems may consider using warning devices which provide audible concentrations under 30
ppm.
HUSH FEATURE
The hush feature is for your convenience only and will not correct a CO problem. Always check
your home for a potential problem after any alarm. Failure to do so could result in injury or death.
NEVER remove the battery from your CO Alarm to silence the horn. Use the silence feature as
removing the battery stops your protection! See ‘WHAT TO DO IF ALARM SOUNDS’ section for
details on responding to an alarm.
The hush feature is intended to temporarily silence your alarm while you correct the problem - it
will not correct a CO problem. While the alarm is silenced, it will continue to monitor the air for
CO. when the CO reaches alarm levels the alarm will sound - repeating the horn pattern: 4beeps,
a pause, 4beeps, etc.
Press and hold the test/silence button until the horn is silent. The initial silence cycle will last
approximately 4minutes.
Note: After the initial 4minute silence cycle, the alarm re-evaluates present CO levels and
responds accordingly. If CO levels remain potentially dangerous or start rising higher the alarm
will start sounding again.
While the detector is silenced:
LOW BATTERY SIGNAL
The alarm indicates a low battery with a ‘chirp’ once every minute. This warning should last for
up to 30 days if untouched.
Note: With normal use the battery will last for 3year minimum. However, battery life will be
reduced if a fault occurs with the battery.
UNIT MALFUNCTION
Your CO alarm performs an internal self-diagnosis to make sure that it is functioning properly.
If the CO Alarm... This means...
Is silent for only 4
mins, then starts

If the unit has detected an error, there is a failure warning. The horn sounds 3short ‘chirps’ every
minute. Push and hold Test/Hush buton, Red LED is on. Release Test/Hush button, Red LED is off.
In case of the above failure warning happening, the CO alarm should be replaced to a new one.
If your CO alarm is beeping, and you are not sure if it is a CO alarm or a malfunction alert then
reset the alarm, open windows for ventilation and turn off fuel-burning appliance (like kerosene or
oil heaters, furnaces, wood-burning stoves, water heaters or other fossil-fuel burning appliances).
END OF LIFE WARNING
The horn sounds 2short ‘chirps’ following with 1long ‘chirp’ every minute. In case of the above
warning happened, the CO alarm is at the end of its life, and the CO alarm should be replaced to
a new one.
Never ignore a CO unit’s alarm. A true alarm is an indication of a potentially dangerous level of
carbon monoxide before an emergency, before most people would experience symptoms of carbon
monoxide poisoning, giving you time to resolve the problem calmly.
• Test your CO Alarm once a week. If the CO Alarm ever fails to test correctly, have it replaced
immediately. If the CO Alarm is not working properly, it cannot alert you to a problem.
• DO NOT stand close to the alarm when it is sounding. Exposure at close range may be harmful
to your hearing. When testing, step away when alarm starts sounding.
1. Push and hold the Test/Silence button on the cover until the LED flashes.
The alarm horn will sound 4beeps, a pause, then 4beeps. The red light will flash. The alarm
sequence should last 5-6 seconds.
2. If the alarm does not sound, give the alarm a clean using a vacuum cleaner to ensure it is
clean and dust free. Then install fresh 9V batteries and test the alarm again. If the unit still
does not alarm, replace it immediately.
WARNING:
• DO NOT try fixing the alarm yourself - this will invalidate your warranty.

CO Alarm Replacement
CO Alarms don’t last indefinitely. CO Alarms are sophisticated electronic devices. Although the
alarm and it’s component parts have undergone stringent tests, and are designed to be very
reliable, it is possible that parts can fail. Therefore you should test your CO Alarm weekly. The CO
Alarm must be replaced in 3years or by the recommended replacement date, see label on the
underside of the unit.
Clean the CO alarm at least once a month to remove dust, dirt or debris.
Using the soft brush or wand attachment to a vacuum cleaner, clean all
sides and the cover of the alarm. Be sure all the vents are free from debris.
If necessary, use a damp cloth to clean the alarm cover.
IMPORTANT: Do not attempt to remove the cover to clean inside the
alarm as this will void your warranty.
CLEANING
WHAT TO DO IF ALARM SOUNDS
If your ACOMN initiates an alarm signal it is recommended that the following actions are taken in
the order given.
1. Keep calm and open all doors and windows to increase the rate of ventilation. Stop using all
fuel-burning appliances and ensure, if possible that they are turned off.
2. If the apparatus continues to operate, even after being reset (where appropriate) then evacuate
the premises. Leave the doors and windows open, and only re-enter the building to operate
periodically any reset facility until the alarm has stopped extreme care should be taken to
minimise personal risk. In multi-occupancy and multi-storey premises, ensure that all the
occupants are alerted to the risk.
3. Get medical help for anyone suffering the effects of carbon monoxide poisoning, and advise
that carbon monoxide inhalation is suspected.
4. Telephone the appropriate appliance servicing and/or maintenance agency or, when necessary,
the relevant fuel supplier on their emergency number, so that the source of carbon monoxide
emissions can be identified and corrected. Unless the reason for the alarm is obviously
