Carbon Monoxide Alarm Procedure
1) Operate the Test/Reset button;
2) Call your emergency services (Fire Department or 911);
3) Immediately move to fresh air - outdoors or by an open door/
window. Do a head count to check that all persons are
accounted for. Do not reenter the premises nor move away
from the open door/window until the emergency services
responders have arrived, the premises have been aired out, and
your alarm remains in its normal condition.
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 equip-
ment serviced immediately. Note any combustion equipment not
inspected by the technician and consult the manufacturer’s instruc-
tions, or contact the manufacturer’s 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 adja-
cent to the residence.
Never restart the source of a CO problem until it has been
corrected. Never ignore the sound of the alarm!
If the alarm is sounding, pressing the test/reset button will
terminate the alarm. If the CO 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 CO which can quickly become a dangerous situation.
WARNING: Activation of the CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can kill you.

Welcome
Note: Many times throughout this User’s Guide, we will refer to
Carbon Monoxide as “CO”.
This Kidde 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. 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
IMPORTANT: This carbon monoxide alarm is designed to detect
carbon monoxide from ANY source of combustion. It is NOT
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 pro-
tect you and your family from fire and its related hazards.
CAUTION: This alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in
other areas.

Important Warning Statements
WARNING: This product is intended for use in ordinary indoor
locations of family living units. It is not designed to measure
compliance with Occupational Safety and Health Administration
(OSHA), commercial or industrial standards. It is not suitable for
installation in hazardous locations as defined in the National
Electric Code.
The installation of this device should not be used as a substitute
for proper installation, use and maintenance of fuel burning
appliances, including appropriate ventilation and exhaust sys-
tems. It does not prevent CO from occurring, nor can it solve and
existing CO problem.
WARNING: This device is designed to protect individuals from
acute effects of carbon monoxide exposure. It may not fully safe-
guard individuals with specific medical conditions. If in doubt,
consult a medical practitioner.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon mon-
oxide concentrations under 30 PPM.
This carbon monoxide alarm requires a continuous supply of elec-
trical power – it will not work without power. Models without
battery backup will not operate during power failure.
This alarm has not been investigated for carbon monoxide detec-
tion below 70 PPM.

1. Information About Carbon Monoxide
General Carbon 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 manual and discuss your CO alarm emer-
gency 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
Carbon Monoxide PPM Levels
(model KN-COPP-B-LPM with digital display only)
Model KN-COPP-B-LPM 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 read-
ings 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. Kidde recommends you take action to eliminate
the source of CO. See “What to do When the Alarm Sounds” (inside
front cover).
IMPORTANT: Model KN-COB-B-LPM does not have a digital dis-
play and does not display carbon monoxide levels in PPM. If the
alarm sounds, it should be treated as a potentially serious condi-
tion. See “What to do When the Alarm Sounds” (inside front cover).
Possible Sources of Carbon 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, pro-
pane, 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, cor-

1. Information About Carbon Monoxide
roded 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.
Conditions That Can Produce Carbon 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 veloc-
ity, 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 com-
pany for assistance.
Information About Carbon 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.

1. Information About Carbon Monoxide
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 Kidde unit has a time-weighted alarm – the higher the level of
CO present, the sooner the alarm will be triggered.
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 temporar-
ily 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 in sections 2 and 3 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.
Instruct children never to touch, unplug or otherwise interfere with the
alarm. Warn children of the dangers of CO poisoning.

Recommended Installation Locations
CO alarms should be mounted in
or near bedrooms and living areas.
It is recommended that you install
a Kidde CO alarm on each level of
your home.
When choosing your installation
locations, make sure you can hear
the alarm from all sleeping areas. If
you install only one CO alarm in your home, install it near bedrooms,
not in the basement or furnace room.
• When wall mounting, place out of reach of children. Under no
circumstances should children be allowed to handle the CO alarm.
• Placing the alarm at eye level allows for optimum monitoring of the
digital display.
