Carbon Monoxide Alarm Procedure
If the alarm sounds 4 quick “beeps”, 5 seconds off:
1) Immediately move to fresh air – outdoors. Check that all
persons are accounted for. Do not re-enter the premises
until the emergency services responders have arrived, the
premises have been aired out, and your alarm remains in
its normal operating condition.
2) Call your local emergency service.
(firedepartment or 911)
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.
PHONE NUMBER:
What to do When the Alarm Sounds!

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 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.

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 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 systems.
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
safeguard 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
monoxide concentrations under 30 PPM.
This carbon monoxide alarm requires a continuous supply of
electrical 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
detection 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
emergency procedure with all the members of your family. Never ignore
aCO 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!
Carbon Monoxide PPM Levels
The 900-0099 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.

1. Information About Carbon Monoxide
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. Kidde recommends you take action to
eliminate the source of CO. 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,
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 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.
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. Learnthe 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.

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
amalfunction, 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.
•CObeing 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.
Instruct children never to touch, unplug or otherwise interferewith the
alarm. Warn children of the dangers of CO poisoning.

3. Installation Locations
•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
components 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 4.4°C
(40°F) or hotter than 37.8°C (100°F) 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 wheredrapes, furnitureor other objects block the flow of air to
the vents.
•Do not install on a switched or dimmer-controlled outlet.

Battery Installation
Install the battery by first removing the battery door and the battery pack.
Align the connector with the slot in the battery. Insure the orientation of
the two alignment ribs align with the slot in the battery. (Red dot on
battery will align with red wire). Press the connector in until it is fully
seated. See drawing below. Depending on the charge state of the battery
pack (the battery packs can have different amounts of energy stored in
them due to storage time), you may hear the alarm sound briefly to
indicate the alarm is receiving power. Be sure to correctly insert battery
into the battery compartment, as shown in drawing below. After
inserting battery, replace back door.
WARNING: Do not use any other type of rechargeable battery in your
alarm or attempt to recharge the battery pack yourself. Improper
charging may even cause the battery pack to overheat or leak, thus
posing possible injury to the user.

5. 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 patternis 4 quick beeps followed by 5
seconds of silence. This cycle repeats as long as a dangerous CO
conditions exist.
WARNING: When powered by battery backup only; after four minutes,
the alarm will sound and flash only once every minute, until the alarm is
reset or the CO is eliminated.
If the battery is low or missing, or if the unit malfunctions, it will display
other readings (and alarm differently) to alert you of specific conditions.
Please familiarize yourself, and other family members, to the difference
between a CO reading and and indication signifying a problem with the
unit itself.
WARNING: If at any time you test the alarm and it does not perform as
described, have it replaced immediately.
4. Carefully replace the back door. Insure the “latches” on all four
corners of the door are lined up, then press the door securely into
place.
5. Mark the location for the two mounting holes on the wall spaced
vertically 2 5/8" apart.
6. If you are mounting the alarm in plaster board or
drywall, drill a 3/16" hole into the wall and insert
the plastic anchors provided. Install the two screws
provided into the wall or wall anchors until the
screw head is approximately 1/8" from the wall.
7. Hook the unit over the screw head and into the
keyhole in back of the unit.
8. Plug the adapter into an unswitched wall socket.
Table Top Alarm
You can use your Kidde CO alarm as a table top unit. Follow steps 1
thru 4 above. Instead of mounting the unit to a wall, pull out the slide
support and place in a location that is easily visible. Be sure the alarm is
no morethan three feet from the floor.

6. Operating Characteristics
Whenever the alarm is operating, the digital display will display “0” to
indicate the unit is monitoring for CO. If the alarm senses dangerous
levels of CO, the digital display will indicate the CO concentration in
parts per million (PPM), and the alarm will emit an audible alarm
pattern.
This alarm will display a “0” if CO concentrations between 0 and 30
PPM have been detected within the last 15 seconds.
When the unit is first powered up, the digital display will show three
“eights” – indicating the alarm is in the start-up mode. The three
“eights” will remain for approximately 20 seconds. After 20 seconds,
the alarm should display “0” and begin monitoring the air for CO and
will continue to do so as long as it receives power.
The following table illustrates the possible digital displays, describes the
audible alarm patterns, and the recommended actions to take.

6. Operating Characteristics
Peak Level Memory
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. 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.
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.

7. 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. The display will show three “eights” and
then show a number – usually around 200). 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.
Battery Replacement
NOTE: This CO alarm is not battery operated. However, these alarms
are equipped with 8 volt Lithium Ion battery backup – the 8 volt battery
is to supply short term back-up during a power outage.
WARNING: Replace the battery pack only with a Kidde
rechargeable battery pack. Replacement battery packs can be
purchased from Kidde customer service.
Upon initial power up or after the alarm has operated on battery backup
and depending on the charge state of the battery, it could take up to 20
hours to FULLYcharge the battery.
During the first 10-hour initial charge period or, until the battery has
charged, “Lb” will be displayed along with the CO level (usually “0”)
and without an audible “beep”. When the initial charge is complete, the
“Lb” will disappear. If however, after 10 hours the battery is not
charging properly, “Lb” may continue to flash AND there will be an
audible “beep” once every 15 seconds indicating the battery is not
charging. If this occurs, make sure the connection between the battery
and the alarm is correctly oriented and fully seated. If not, disconnect
the battery and reconnect insuring the alignment ribs match the slot in
the battery. If it is properly connected and fully seated and “Lb” is still
displayed along with an audible “beep”, contact customer service.

7. Maintenance
Lithium Ion Battery Handling Precautions
Handling
•Do not use the battery for a purpose other than for the alarm it is
specified.
• Do not recharge the battery using any charging circuit other than the
one provided in the alarm. A recharging operation under non-
conforming recharging conditions can cause electrolyte leakage,
overheating, smoke emission, bulging/bursting and/or ignition.
•Do not discard the battery into fire or heat it under any circumstances.
Otherwise, it may cause the battery to explode. Do not connect the
battery to an electrical outlet.
•Do not connect the positive and negative terminals of the battery with
any conductor such as metal wires. Do not store the battery or
transport it together with any metal objects.
•Do not disassemble or modify the battery pack under any
circumstances. Disassembling the battery can cause internal shorts,
resulting in bulging/bursting due to excess gas generation, overheat,
ignition, explosion or other problems.
•Do not pierce the battery with sharp objects or subject to any other
mechanical forces. Do not use an apparently damaged or deformed
battery.
•Do not use or leave the battery near a heat source such as a fire or
heater. Do not place the battery in microwave oven or on induction
heaters.
•Do not use or subject the battery to intense sunlight or hot
temperatures. Otherwise, electrolyte leakage, overheating and/or
smoke emission can occur. Also, its guaranteed performance will be
lost and/or its service life will be shortened.
•Do not subject the battery to static electricity. Otherwise, the built-in
safety/protection circuits can be damaged by static voltages, possibly
leading to leakage, overheating, smoke emission, bursting and/or
ignition.
•Do not immerse the battery in liquids such as fresh or salt water,
beverages (fruit juices and coffee, etc.)
•If the battery leaks, and the electrolyte gets into the eyes, the skin or
other part of the body,rinse the body part with clean running water

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
proper sensor operation.

contamination of the sensor,prior to performing any of the following:
•Staining or stripping floors or furniture, painting or wall-papering
•Using aerosols or adhesives

continuous protection.
The following is a list of substances that at high levels can damage the
sensor or cause temporary readings that are not CO readings:
•Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl
acetate, hydrogen, hydrogen sulfide and sulfur dioxide.
