Carbon Monoxide Alarm Procedure
WARNING: Activation of the CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can kill you.
What to do When the Alarm Sounds!
If alarm sounds 4 quick beeps, 5 seconds off:
1) Operate Test /Reset button.
2) Call your emergency services (FIRE DEPT or 911).
3) Immediately MOVE TO FRESH AIR – outdoors or by an open
door / Window.
4) After following steps 1-3, if the alarm reactivates within a 24
hour period, repeat steps 1-3 and call a qualified appliance
technician to investigate sources of CO from fuel burning
equipment and appliances, and to inspect for proper operation
of equipment.
If problems are identified during this inspection, have the
equipment serviced immediately. Note any combustion equipment
not inspected by the technician and consult the manufacturer’s
instructions, or contact the manufacturer directly for more
information about CO safety and the equipment. Make sure that
motor vehicles are not, or have not been, operating in a garage
attached or adjacent to the residence.
Never restart the source of a C problem until it has been
corrected. Never ignore the sound of the alarm!
If the alarm is sounding, pressing the Test/Hush button will
terminate the alarm. If the C condition that caused the alert
in the first place continues, the alarm will reactivate. If the
unit alarms again within six minutes, it is sensing high levels
of C which can quickly become a dangerous situation.

Welcome
Note: Many times throughout this User Guide, we will refer to
Carbon Monoxide as “C ”.
This Carrier carbon monoxide (CO) alarm is an important part of your
family’s home safety plan. This alarm has been designed and tested to
detect CO buildup in a residential environment. Your alarm is for use
specifically in the home, but not for use in a boat or recreational vehicle.
As an owner of a CO alarm, there are some basic facts you should know
about for your protection.
Many people think that CO alarms operate like smoke alarms. Like
smoke alarms, CO alarms monitor the air in your home and sound a
loud alarm to warn you of trouble. The way you respond to a CO alarm
is quite different than a smoke alarm. That’s because a house fire and a
CO problem are two distinctly different situations. If your smoke alarm
were to alarm, you would quickly be able to judge the level of danger
you were in with your senses. You can see and smell the smoke, feel the
heat, see, and possibly hear the fire burning. You can also readily see if
your smoke alarm is alarming in a non-emergency situation. Because
your sense of sight, smell, hearing and touch give you information, you
can almost instantly judge what action to take if you hear your smoke
alarm.
CO is an invisible, odorless, tasteless and non-irritating gas – completely
undetectable to your senses. That’s why it is important to your safety
that you have a CO alarm.
Important Warning Statements
IMP RTANT: This carbon monoxide alarm is designed to detect
carbon monoxide from ANY source of combustion. It is N T
designed to detect smoke, fire, or any other gas.
WARNING: Carbon monoxide alarms are not smoke alarms.
This carbon monoxide alarm is not a substitute for installing and
maintaining an appropriate number of smoke alarms in your
home.
This carbon monoxide alarm will not sense smoke, fire, or any
poisonous gas other than carbon monoxide even though carbon
monoxide can be generated by fire. For this reason you must
install smoke alarms to provide early warning of fire and to
protect you and your family from fire and its related hazards.
CAUTI N: This alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in
other areas.

1. Information About Carbon Monoxide
General Car on Monoxide Information
Carbon monoxide is a colorless, odorless and tasteless poison gas that
can be fatal when inhaled. CO inhibits the blood’s capacity to carry
oxygen.
Periodically review this alarm user guide and discuss your CO alarm
emergency procedure with all the members of your family. Never ignore
a CO alarm. A true alarm is an indication of potentially dangerous levels
of CO. CO alarms are designed to alert you to the presence of CO
before an emergency – before most people would experience symptoms
of CO poisoning, giving you time to resolve the problem calmly.
Determine if anyone in the household is experiencing symptoms of CO
poisoning. Many cases of reported CO poisoning indicate that while
victims are aware they are not well, they become so disoriented they are
unable to save themselves by either exiting the building or calling for
assistance. Also, young children and household pets may be the first
affected. You should take extra precautions to protect high-risk persons
from CO exposure because they may experience ill effects from CO at
levels that would not ordinarily affect a healthy adult.
Symptoms of CO Poisoning
The following common symptoms are related to CO poisoning and
should 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.
If you experience even mild symptoms of CO poisoning, consult your
doctor immediately!

1. Information About Carbon Monoxide
Car on Monoxide PPM Levels
Model COALMCCNRB02-A10 is equipped with a digital display that
shows levels of CO (displayed in PPM – parts per million). Learn the
difference between dangerous, high, mid and low levels.
Dangerous Levels:
When someone is experiencing symptoms of CO poisoning and CO
readings are generally above 100 PPM. Anytime someone is experiencing
the symptoms of CO poisoning this should be treated as an emergency.
See “What to do When the Alarm Sounds” (inside front cover).
High Levels:
Generally above 100 PPM, with no one experiencing symptoms. This
should be treated as an urgent situation. See “What to do When the
Alarm Sounds” (inside front cover).
Mid Levels:
Generally between 50 PPM to 100 PPM. This should be cause for
concern and should not be ignored or dismissed. See “What to do
When the Alarm Sounds” (inside front cover).
Low Levels:
Generally below 50 PPM. Carrier recommends you take action to
eliminate the source of CO. See “What to do When the Alarm Sounds”
(inside front cover).
Possi le Sources of Car on Monoxide
Inside your home, appliances used for heating and cooking are the most
likely sources 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:
• Automobiles, furnaces, 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 furnace
exchangers.
• Vehicles and other combustion engines running in an open or closed
garage, attached or near a home.
• Burning charcoal or fuel in grills and hibachis in an enclosed area.

1. Information About Carbon Monoxide
Conditions That Can Produce Car on Monoxide
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, furnaces, 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,
fireplace, etc.).
• Temperature inversions which can trap exhaust gases near the ground.
• 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 defense is an annual inspection and regular maintenance of your
appliances. Contact a licensed contractor or call your local utility
company for assistance.
Information A out Car on Monoxide Alarms –
What They Can and Cannot Do:
CO alarms provide early warning of the presence of CO, usually before a
healthy adult would experience symptoms. This early warning is possible,
however, only if your CO alarm is located, installed and maintained as
described in this guide.
Because carbon monoxide is a cumulative poison, long-term exposures to low
levels may cause symptoms, as well as short-term exposures to high levels.
This Carrier unit has a time-weighted alarm – the higher the level of CO
present, the sooner the alarm will be triggered.

1. Information About Carbon Monoxide
This CO alarm can only warn you of the presence of CO. It does not prevent
CO from occurring, nor can it solve an existing CO problem. If your unit has
alarmed and you’ve provided ventilation by leaving your windows and doors
open, the CO buildup may have dissipated by the time help responds.
Although your problem may appear to be temporarily solved, it’s crucial that
the source of the CO is determined and that the appropriate repairs are made.
This CO alarm is designed to act as a monitor; it is not designed for use as a
short-term testing device to perform a quick check for the presence of CO.
CO alarms have limitations. Like any other electronic device, CO alarms are
not fool-proof. CO alarms have a limited operational life. You must test your
CO alarm weekly, because it could fail to operate at any time.
If your CO alarm fails to test properly, or if its self-diagnostic test reveals a
malfunction, immediately have the unit replaced. This alarm will not monitor
CO levels while in an error condition.
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. The rate and
ability that which CO reaches the alarm may be affected by:
• Doors or other obstructions.
• Fresh air from a vent, an open window or other source.
• CO being present on one level of the home and not reach a CO alarm
installed on a different level. (For example, CO in the basement may not
reach an alarm on the second level, near the bedrooms).
For these reasons, we recommend you provide complete coverage by placing
a CO alarm on every level of the home. Please carefully read all information
on properly installing this CO alarm.
CO alarms should not be used to detect the presence of natural gas
(methane), propane, butane, or other combustible fuels.
