Part Four – What to Do When the Alarm Sounds for Carbon Monoxide
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 build-
ing or calling for assistance. Also young children and household pets may be the first affected. The following symptoms are related
to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household:
Common Mild Exposure Symptoms:
Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Common Medium Exposure Symptoms:
Throbbing headache, drowsiness, confusion, fast heart rate.
Common Extreme Exposure Symptoms:
Convulsions, unconsciousness, heart and lung failure. It can cause brain damage and death.
If you experience even mild symptoms of CO poisoning, consult your doctor immediately!
If the alarm sounds for carbon monoxide:
1) Operate test/reset button;
2) Call your emergency services ( fire dept. or 911);
3) 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 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 CO and Gas 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 quali-
fied technician 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 immediately.
Note any combustion equipment not inspected by the technician and consult the manufacturer’s instructions,
or contact the manufacturer’s 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.
Actuation of your CO and Gas alarm indicates the presence of
Carbon Monoxide (CO) or explosive Gas which can KILL YOU.
When the CO and Gas alarm senses a dangerous level of CO, the unit will emit a loud alarm pattern and display the concentra-
tion of CO in parts per million (PPM). The alarm pattern is 4 short beeps – followed by 5 seconds of silence – followed by 4 short
beeps repeating. (Note: When the unit is disconnected from the 120V power supply and is on battery backup, the alarm pattern will
continue for the first 4 minutes after detecting CO and then the cycle will repeat every one minute). Know how to respond to a CO
or Gas emergency. Periodically review this user’s guide and discuss with all members of your family.
