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 ignorethe 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’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 fireand 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!

1. Information About Carbon Monoxide
Carbon Monoxide PPM Levels
(model 900-0230 with digital display only)
Model 900-0230 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. Kidde recommends you take action to
eliminate the source of CO. See “What to do When the Alarm Sounds”
(inside front cover).
IMPORTANT: Model 900-0233 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,
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.

1. Information About Carbon Monoxide
•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.
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.

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
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
arenot 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 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 interferewith 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
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.

6. Model 900-0230 (with digital display)
Operating Characteristics
Peak Level Memory (model 900-0230 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.

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 4 minutes – and then 4 quick beeps
once every minute as long as dangerous CO 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).

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 900-0230 with digital
display: The display will show three “eights” and then show a number
–usually around 200). 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
Tokeep 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.
Move the CO Alarm to a remote location, to prevent possible damage or
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
WARNING: Reinstall the CO Alarm as soon as possible to assure
continuous protection.
