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. 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 appliance 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 manufacturers' 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.
INSTALLING THE ALARM FOR RESIDENTIAL USE
LOCATION
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 warning of CO is best achieved by the installation of CO alarms on all floors and areas of the
household including attached garages. Placement of a alarm in a garage may cause an alarm due to
CO from automotive exhaust.
RECOMMENDATIONS
Put a CO alarm inside each bedroom where the occupant closes the door while sleeping. Particulate
smoke can be blocked by a closed door, but CO fumes are likely to get through.
