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 indi-
cate 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 house-
hold 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 appliances,
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 pres-
ent 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
presence 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 per-
sons 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 techni-
cian (_________________) to investigate for sources of CO
from fuel burning equipment and appliances, and inspect for
proper operation of this equipment. If problems are identified
during this inspection, have the equipment serviced immedi-
ately. Note any combustion equipment not inspected by the
technician and consult the manufacturers’ instructions or
contact the manufacturers directly for more information
about CO safety and this equipment. Make sure that motor
vehicles are not and have not been operating in an attached
garage or adjacent to the residence.
5.1 IMPORTANT CONSIDERATIONS The 12-24SIR 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 pro-
duced by the alarm is loud because it is designed to awaken a
person in an emergency. Prolonged exposure to the alarm at a
close distance 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
hazards 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 poisoning.
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 manu-
al
6.2 Develop a family escape plan and practice it with your entire fam-
ily, 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 natural
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 con-
ditions 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 residence 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.
