Carbon monoxide (CO) is an insidious poison. It is a colorless,
odorless and tasteless gas. It is a cumulative poison. Even low
levels of CO have been shown to cause brain and other vital organ
damage in unborn infants with no effect on the mother.
The following symptoms are related to CARBON MONOXIDE
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
Many cases of reported CARBON MONOXIDE 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 chil-
dren and household pets may be the first affected.
Your CO alarm is designed to detect the toxic CO gas that result
from incomplete combustion, such as those emitted from appli-
ances, furnaces, fireplaces and auto exhaust.
A CO Alarm is NOT A SUBSTITUTE for other combustible gas,
fire or smoke alarms. This carbon monoxide alarm is designed to
detect carbon monoxide gas from ANY source of combustion.
CAUTION:
This alarm will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be present
in other areas.
WARNING:
This product is intended for use in ordinary indoor
locations of family living units. It is not designed to comply with
Occupational Safety and Health Administration (OSHA) commer-
cial or industrial standards. Individuals with medical problems
may consider using warning devices that provide audible and visu-
al signals for carbon monoxide concentrations under 30 ppm.

WARNING:
Activation of this device indicates the pres-
ence of carbon monoxide (CO), which can KILL YOU. If
alarm sounds:
1) Operate reset/silence button;
2) Call your emergency services (__________________)
[fire department or 911];
3) Immediately move to fresh air – outdoors or by an
open door/window. Then, do a head count to check
that all persons are accounted for. Do not reenter 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.
4) After following steps 1-3, if your alarm reactivates
within a 24-hour period, repeat steps 1-3 and call a
qualified technician
(_________________) to
investigate for sources of CO from fuel burning equip-
ment and appliances, and inspect for proper operation
of this equipment. If problems are identified during this
inspection, have the equipment serviced immediately.
Note any combustion equipment not inspected by the
technician and consult the manufacturers’ instructions
or contact the manufacturers directly for more informa-
tion about CO safety and this equipment. Make sure
that motor vehicles are not and have not been operat-
ing in an attached garage or adjacent to the residence.
5.1 IMPORTANT CONSIDERATIONS The FW-CO1224 has been
designed and is warranted to operate for six years.
5.2 The alarm will automatically sense when the level of CO in the
air falls below the danger level. You should stay outside the resi-
dence in fresh air until the alarm is silenced. When the alarm
sounds, do not stand too close to the alarm. The sound produced
by the alarm is loud because it is designed to awaken a person in
an emergency. Prolonged exposure to the alarm at a close dis-
tance may be harmful to your hearing.

This CO alarm can quickly alert you to the presence of CO but it
cannot prevent toxic CO emissions. Please note that there are haz-
ards against which CO detection may not be effective, such as gas
leaks or explosions. The ultimate responsibility for protection
against toxic CO gas rests solely on you. Installing CO alarms is
just the first step in protecting your family from toxic CO poison-
ing. We also suggest that you create an effective, comprehensive
safety program as outlined below.
6.1
Install CO alarms properly following the instructions in this
manual
6.2
Develop a family escape plan and practice it with your entire
family, especially small children.
– Draw a floor plan of your home/ residence and find two ways to
exit from each room. There should be one way to get out of each
bedroom without opening the door.
– Make sure that all occupants know what the CO alarm signal
means and how they must be prepared to leave the residence by
themselves if necessary.
– Decide on a meeting place a safe distance from your house and
make sure all occupants understand where they should go and wait
if there is a dangerous CO condition.
– Conduct CO safety drills at least every 6 months to make sure
that every one, even small children, know what to do in order to
escape safely.
– Know where to go to call the Fire Department from outside your
residence.
This unit is designed to detect carbon monoxide (CO) entering its
sensing chamber. It does not sense combustible gas (such as natu-
ral gas, propane or butane), heat, smoke or flames.
When properly located, installed, and maintained, this CO alarm is
designed to provide early warning of developing poisonous CO
conditions at a reasonable cost. This alarm monitors the air, and
when it senses CO, it activates its built-in alarm. It can provide
precious time for you and your family to escape from your resi-
dence before CO can seriously injure or kill. However, such an
early warning is possible only if the alarm is located, installed, and
maintained as specified in the Owner’s Manual.

If bedroom doors are usually closed at night, alarms should be
placed in each bedroom as well as in the common hallway between
them. CO alarms may not sense CO on a different level of a residence
or building. For example, a second floor alarm may not sense a CO
leak on the first floor or in the basement.
Therefore, alarms should be placed on every level of a residence
or building. If the alarm is located outside of a bedroom, it may not
wake up a sound sleeper, especially if the bedroom door is closed or
only partly open. If the alarm is located on a different level of the res-
idence than the bedrooms, it is even less likely to wake up people
sleeping in the bedroom. Installing CO alarms may qualify you for
lower homeowner’s insurance rates, but CO alarms are not a substi-
tute for insurance. Homeowners and renters should continue to insure
their lives and property.
WARNING:
The NAPCO Model FW-CO1224 CO Alarm
is not
designed for marine, RV, or aeronautical use.
NOTE:
This unit contains no batteries and will not operate with-
out power.

8.1 RECOMMENDATIONS
One of the most important considerations in any CO alarm system
is the location of the alarms. Statistics of the National Fire
Protection Association (NFPA) show that most of the fatal CO
occurrences happen at night while people are sleeping. Early warn-
ing of CO is best achieved by the correct installation of CO
alarms. Placement of an alarm in a garage may cause an alarm due
to CO from automotive exhaust.
8.2 RECOMMENDED MOUNTING LOCATIONS
Put a CO alarm inside each bedroom where the occupant closes
the door while sleeping. A closed door can block particulate
smoke, but CO gas is likely to get through.
Figure 1:
Recommended CO alarm placement for single floor residence.
Figure 2:
Recommended CO alarm place-
ment for multi-level residence.
8.3 This CO alarm must be mounted on the wall or ceiling.
8.4 WALL LOCATION: Locate top of alarm 5-6 feet from the floor.
Figure 3:
Recommended CO alarm mounting location is 5 to 6 feet from
floor.
8.5 CEILING LOCATION:
Alarm should be mounted as close as possible to the center of a
hallway or room. If this is not possible, the edge of the alarm
should be at least 4 inches from any wall.
8.6 LOCATIONS TO AVOID
Placing units where they will not operate properly causes nuisance
alarms.To avoid nuisance alarms, do not place units:
– Within 5 feet (1.5m) of any cooking appliance or furnace.
!
!
– Near an open window or door, because the fresh air entering the
opening may delay CO from reaching the alarm.
– In damp or very humid areas or next to bathrooms with show-
ers. Install detectors at least 10 feet (3 meters) away from bath-
rooms.
– In very cold or very hot environments or in unheated buildings
or outdoor rooms where the temperature can go below or above
the operating range of the alarm. Temperature limits for proper
operation are 4.4° C to 37.8° C (40° F to 100° F).
– Good ventilation is recommended when household cleaning
supplies or similar contaminants are stored or frequently used.
8.7 CONDITIONS WHICH CAN RESULT IN TEMPORARY CO
SITUATIONS:
8.7.1Excessive spillage or reverse venting of fuel burning appli-
ances caused by outdoor ambient conditions, such as:
i) Wind direction and/or velocity, including high gusts of wind.
Heavy air in the vent pipes (cold/humid air with extended peri-
ods between cycles).
ii) Negative pressure differential resulting from the use of
exhaust fans.
iii) Simultaneous operation of several fuel burning appliances
competing for limited internal air.
iv) Vent pipe connections vibrating loose from clothes dryers,
furnaces, or water heaters.
v) Obstructions in or unconventional vent pipe designs which
can amplify the above situations.
8.7.2Extended operation of unvented fuel burning devices (range,
oven, fireplace, etc.)
8.7.3Temperature inversions, which can trap exhaust gasses near
the ground.
8.7.4Car idling in an open or closed area garage, or near a home.
