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.

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’s guide 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!
21008088B_10Y_V2.indd 521008088B_10Y_V2.indd 5 2012.9.14 10:17:56 AM2012.9.14 10:17:56 AM

1. Information About Carbon Monoxide
Carbon Monoxide PPM Levels
(model KN-COPP-B-LP with digital display only)
Model KN-COPP-B-LP 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-LP does not have a digital display
and does not display carbon monoxide levels in PPM. If the alarm
sounds, it should be treated as a potentially serious condition. 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-
21008088B_10Y_V2.indd 621008088B_10Y_V2.indd 6 2012.9.14 10:17:56 AM2012.9.14 10:17:56 AM

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.
21008088B_10Y_V2.indd 721008088B_10Y_V2.indd 7 2012.9.14 10:17:56 AM2012.9.14 10:17:56 AM

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 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.

Locations To Avoid
IMPORTANT: Improper location can affect the sensitive electronic com-
ponents in this alarm. To avoid causing damage to the unit, to provide
optimum performance, and to prevent unnecessary nuisance alarms:
• Do not install in kitchens, garages or furnace rooms that may expose
the sensor to substances that could damage or contaminate it.
• Do not install in areas where the temperature is colder than 40°F
(4.4°C) or hotter than 100°F (37.8°C) such as crawl spaces, attics,
porches and garages.
• Do not install within 5 ft. of heating or cooking appliances. (Kidde
recommends 15 ft. to prevent nuisance alarms).
• Do not install near vents, flues, chimneys or any forced/unforced air
ventilation openings.
• Do not install near ceiling fans, doors, windows or areas directly
exposed to the weather.
• Do not install in dead air spaces, such as peaks of vaulted ceilings or
gabled roofs, where CO may not reach the sensor in time to provide
early warning.
• Do not install this unit near deep-cell large batteries. Large batteries
have emissions that can cause the alarm to perform at less than
optimum performance.
• Do not obstruct the vents located on the alarm. Do not place the
alarm where drapes, furniture or other objects block the flow of air
to the vents.

Battery Installation and Replacement
To install or replace the batteries in this Kidde CO alarm, please perform
the following steps.
1. Slide open the bottom cover to expose the battery compartment.
2. If replacing batteries, remove the old batteries and properly dispose
of them as recommended by the battery manufacturer.
3. Install the new batteries. Note the polarity
illustration in the battery compartment.
4. Close the bottom cover. Note: The bot-
tom cover will not close if all three AA
batteries are not installed.
When replacing the batteries, use one of
the following approved brands:
• Duracell MN1500 or MX1500
• Energizer E91
• Gold Peak 15A
• Golden Power GLR6A
These batteries can be purchased where you bought the alarm or at a
local hardware store. Use of a different
battery may have a detrimental effect on the alarm operation.
IMPORTANT: Constant exposures to high or low humidity may reduce
battery life. A good safety measure is to replace the battery at least
once a year, or at the same time as you change your clocks for daylight
saving time.
After installing or changing the batteries, reinstall your alarm. Test
your alarm by using the Test/Reset button and check that the green LED
flashes once approximately every 30 seconds.

Mounting
This CO alarm can be either wall mounted
or placed on a tabletop.
For wall mounting, follow these steps:
1. Remove back mounting plate from the
alarm, place it in the desired location,
and mark the location of the two holes
needed on the wall
2. Insert the two screws provided until the
screw heads are protruding approximately
1/8” from the wall. (If mounting
in a plasterboard or drywall, drill a
3/16” hole in the wall and use the
plastic anchors provided.)
3. Hook the CO alarm over the
screws and onto the keyholes in
the back mounting plate of the
alarm. After the mounting plate
is secured to the wall, slide the
alarm down over the mounting
plate until it snaps into place.
Your CO alarm may also be placed
on a tabletop. If the alarm is not wall mounted, be sure it is no more
than three feet from the floor. The alarm does not have to be within
three feet from the floor to detect CO, but at this height it is less likely
to sustain damage from a fall.
Important Labels Provided
Two labels have been provided that have important information on what
to do in case of an alarm. Add the phone number of your emergency
service provider in the space provided. Place one label next to the alarm
after it is mounted, and one label near a fresh air source such as a door
or window.

6. Model KN-COPP-B-LP (with digital display)
Operating Characteristics
Peak Level Memory (model KN-COPP-B-LP only)
When the Peak Level button is pressed and held, the display shows
the highest CO reading taken by the CO alarm since
its last reset or power up. In this example 120 PPM
was the maximum amount of CO recorded since the
unit was last reset.
The Peak Level display feature will display levels
between 11-999 PPM. Although the Peak Level
feature will display levels below 30 PPM, these levels
will not result in an alarm no matter how long the
device is exposed to these levels. The Peak Level feature is helpful in
identifying if you have had a CO reading since resetting the alarm.
Concentrations of CO between 1 and 30 PPM can often occur in
normal, everyday conditions. Concentrations of CO below 30 PPM may
be an indication of a transient condition that may appear today and
never reappear. Some CO conditions may start out as low level leaks
but could develop into CO concentrations that may become harmful.
If this happens, the CO alarm will detect the dangerous level and
alarm, notifying you and others of the conditions. DO NOT ignore
high concentration readings above 30 PPM or a CO alarming
device that is in alarm.
Peak Level Memory Reset
Press the Peak Level button; with the button still pressed, press the Test/
Reset button for two seconds and release. The number on the display
will turn to “0”, the memory will be cleared and the alarm will begin
monitoring for CO. The Peak Level memory is also reset when the unit
loses power.

8. Maintenance
NOTE: This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your
fingers over the sounder opening while testing your alarm.
Caution: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
Testing
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you will hear 4 quick beeps – followed by 5 seconds of silence
– followed by 4 quick beeps. (For model KN-COPP-B-LP with digital
display: The display will show three “---” and then show “888”.)
The red LED will flash along with the beeps. Within several seconds the
unit will return to monitor for CO.
Note: You do not need to press the Test button to take a CO
reading.
Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
• Avoid spraying air fresheners, hair spray, paint or other aerosols near
the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with
7. Alarm Characteristics
Carbon Monoxide Alarm Indicator
When the alarm senses a dangerous level of CO, the unit will emit a
loud alarm pattern. The alarm pattern is 4 quick beeps followed by 5
seconds of silence, repeating for as long as dangerous conditions exist.
The red Alarm LED will flash the same pattern and the digital display
(where equipped) will indicate CO concentrations in parts per million
(PPM).
