SINGLE STATION CARBON
MONOXIDE ALARM
AC Plug-in Operated with AA Battery Backup
Model: KN-COB-DP2CA (900-0263CO-CA)

Carbon Monoxide Alarm Procedure
If alarm sounds 4 quick beeps, 5 seconds off:
1) 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 re-enter 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.
2) Call your emergency services (Fire Department or 911);
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.

What to do When the Alarm Sounds!

Welcome
Note: Many times throughout this User 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 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 protect 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.

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 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
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,
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.
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 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.

1. Information About Carbon Monoxide
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 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.
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
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.

1. Information About Carbon Monoxide
• CO being present on one level of the home and not reaching 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.

Low Battery Warning
If the battery is missing or battery power is low, the unit will chirp every
60 seconds to indicate the batteries must be replaced.
THE BATTERIES MUST BE REPLACED IMMEDIATELY!
Low Battery Hush®CONTROL
When the batteries need to be replaced, the unit will produce a low
battery warning. The Low Battery Hush®feature allows you to press the
button on the alarm and disable the “chirp” for a random period of up
to 12 hours. This gives you a chance to replace the battery at a more
convenient time by disconnecting the alarm from power. During this
Low Battery Hush®period, your alarm is monitoring for CO.
2. Product Features and Specifications
Tamper Resist Feature
The Tamper Resist feature is optional and DOES NOT need to be
activated for the CO alarm to function properly. The Tamper Resist
feature is a constant 85 dB alert to indicate the unit has been
unplugged or has come loose from the outlet. THIS FEATURE IS
INITIALLY DISABLED FROM THE FACTORY AND MUST BE ACTIVATED
IF FEATURE IS DESIRED. To activate the Tamper Resist feature: Move
the Tamper Resist Activation Slide to the “ON” position. Once
enabled, there is a two minute delay when power is supplied to
give you time to plug in the unit after activating the batteries. This
feature is automatically disabled once the battery voltage has reached
a level to cause a low battery warning chirp. Pressing the Test/Reset
button will defeat the 85 dB tamper alarm for two minutes to allow
time for the batteries to be changed without the alarm sounding.
To deactivate the Tamper Resist feature, press in the Tamper Resist
Activation Switch and move the Activation Slide to the “OFF”
position.
