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).

If the alarm sounds:

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 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 Alarm indicates the presence
of Carbon Monoxide (CO) which can KILL YOU.



When the CO alarm senses a dangerous level of CO, the unit will emit a loud alarm pattern. The alarm pattern is 4 short beeps

– followed by 5 seconds of silence – followed by 4 short beeps. (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 emergency. Periodically review this user’s guide and discuss with all members
of your family.
