consult your doctor immediately!
Alarm Rem oval (for alarms equipped with a 9V battery back-up)
Gen eral CO In form ation
CO alarms provide early warning of the presence of
carbon monoxide, usually before a healthy adult would
experience symptoms. This early warning is possible,
however, only if your Kidde CO alarm is located, installed
and maintained as described in this manual.
CO alarms should not be used to detect the presence of
natural gas (methane), propane, butane, or other
combustible fuels.
Carbon Mon oxide Alarm Procedure
To keep your alarm in good working order, you must fol-
low these simple steps:
If tamper resist feature has been activated, refer to tamper
resist feature description on page 9 for removal
instructions.
Carbon monoxide (CO) is a colorless, odorless, and tasteless
poison gas that can be fatal when inhaled. CO inhibits the
blood’s capacity to carry oxygen.
WARNING: Actuation of the CO Alarm
indicates the presence of Carbon Monoxide
(CO) which can kill you.
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 carbon monoxide present, the sooner the alarm
will be triggered.
Instruct children never to touch, unplug or otherwise
interfere with the alarm. Warn children of the dangers of
CO poisoning.
• Test the alarm once a week by pressing the Test/Reset
button.
Remove the alarm from the mounting plate by rotating the
alarm in the direction of the “OFF” arrow on the cover.
To disconnect the AC Quick-Connector harness, squeeze
the locking arms on the sides while pulling the connector
away from the bottom of the alarm (see Figure 2).
Periodically review this alarm manual 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 carbon
monoxide. CO alarms are designed to alert you to the
presence of carbon monoxide before an emergency -
before most people would experience symptoms of carbon
monoxide poisoning, giving you time to resolve the
problem calmly.
This CO alarm is designed to act as a continuous monitor;
it is not designed for use as a short-term testing device to
perform a quick check for the presence of CO.
• Vacuum the alarm cover once a month to remove
accumulated dust.
CO alarms are not a substitute for property, disability, life
or other insurance of any kind. Appropriate insurance
coverage is your responsibility. Consult your insurance
agent.
If alarm signal sounds 4 quick beeps, 5 seconds off:
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.
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.
• Never use detergents or solvents to clean the alarm.
Chemicals can permanently damage or temporarily
contaminate the sensor.
1) Immediately move to fresh air - outdoors or by an
open door or window. Check that all persons are
accounted for. Do not re-enter the premises or move
away from the open door/window until emergency
services responders have arrived, the premises have
been aired out, and your alarm remains in its normal
operating condition.
After the alarm has been removed, you can open the
battery door and replace the battery. Battery installation
instructions are provided on the inside of the battery door.
• Avoid spraying air fresheners, hair spray, paint or other
aerosols near the alarm.
Possible Sources of CO
If your CO alarm fails to test properly, or if its self-
diagnostic test reveals a malfunction, immediately have the
unit replaced.
When installing the battery, orient the battery as shown on
unit label. Press the battery reminder tab down into the
battery compartment and install the battery (see Figure 4).
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 carbon
monoxide at levels that would not ordinarily affect a
healthy adult.
Inside your home, appliances used for heating and cooking
are the most likely sources of carbon monoxide. Vehicles
running in attached garages can also produce dangerous
levels of carbon monoxide.
• Do not paint the unit. Paint will seal the vents and
interfere with proper sensor operation.
CO alarms can only sense CO that reaches the unit’s
sensor. Carbon monoxide may be present in other areas
without reaching the alarm. The rate at which CO reaches
the unit may be affected by doors or other obstructions.
In addition, fresh air from a vent or open window or any
other source may prevent CO from reaching the sensor.
Please observe cautions in Installation on page 4.
2) Call your emergency local service
(fire deptartment or 911).
Move the CO Alarm to a remote location, to prevent
possible damage or contamination of the sensor, prior to
performing any of the following:

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:
PHONE NUMBER
Battery
tab
• Staining or stripping wood floors or furniture
• Painting or wall-papering
• Using aerosols or adhesives
Never restart the source of a CO problem until it has been
corrected. Never ignore the sound of the alarm!
CO could be 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 this reason, we
recommend you provide complete coverage by placing a
CO alarm on every level of the home.
• 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.
WARNING: Reinstall the CO Alarm as soon as possible to
assure continuous protection.
Sym ptom s of CO Poison in g
The following is a list of substances that at high levels can
damage the sensor or cause temporary readings that are
not carbon monoxide readings:
The following common symptoms are related to carbon
monoxide poisoning and should be discussed with ALL
members of the household. Learn the difference between
dangerous, high, mid and low levels:
• Blocked chimneys or flues, back drafts and changes in air
pressure, corroded or disconnected vent pipes, loose or
cracked furnace exchangers.
CAUTION! If the battery reminder tab is not held down in
the battery compartment by the battery, the battery door will
not close, the AC Quick-Connector will not attach to the
alarm, and the alarm will not attach to the mounting plate.
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene,
ethyl acetate, hydrogen, hydrogen sulfide, sulfur dioxides.
CO alarms are not smoke alarms. CO alarms do not sense
smoke or fire. For early warning of fire you must install
smoke alarms, even though carbon monoxide can be
generated by a fire.
• Vehicles and other combustion engines running in an
open or closed garage, attached or near a home.
Mild Exposure: Headaches, running nose, sore eyes, often
described as “flu-like” symptoms.
Also most aerosol sprays, alcohol based products, paints,
thinners, solvents, adhesives, hair sprays, after shaves,
perfumes, auto exhaust (cold start) and some cleaning
agents.
After installing or changing the battery, reinstall your
alarm. Test your alarm by using the Test/Reset button and
check that the green “Power” LED is on.
• Charcoal/gas grills and hibachis in an enclosed area.
Medium Exposure: Dizziness, drowsiness, vomiting.
Extreme Exposure: Unconsciousness, brain damage, death.
