HOW TO INSTALL YOUR CO ALARM
Read “Where To Install CO Alarms” before starting.
Before you start installation, find the pair of self-adhesive labels
included with this CO Alarm. On each label write in the phone number
of your emergency responder (like 911) and a qualified appliance techni-
cian. Place one label near the CO Alarm, and the other label in the “fresh
air” location you plan to go if the alarm sounds.
IF YOUR CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon
monoxide (CO) which can kill you. In other words, when your
Alarm sounds, you must not ignore it!

4. After following steps 1-3, if your CO 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 con
tact 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.Write down the number of a

Alarms have various limitations.See "General Limitations of CO
Alarms" for details.
USING THE SILENCE FEATURE
• The Silence Feature is for your convenience only and will
not correct a CO problem.Always check your home for a
potential problem after any alarm. Failure to do s
o can result
in injury or death.
• NEVER remove the batteries from your CO Alarm to silence
the horn. Use the silence feature. Removing the batteries
removes your protection! See “If Your CO Alarm Sounds” for
details on responding to an alarm.
The Silence Feature is intended to temporarily silence your CO Alarm’s
alarm horn while you correct the problem—it will not correct a CO prob-
lem.While the alarm is silenced it will continue to monitor the air for CO.
When CO reaches alarm levels the alarm will sound— repeating horn
pattern: 4 beeps, a pause, 4 beeps,etc. Press
and hold the Test/Silence
button until the horn is silent.The initial Silence cycle will last approxi-
mately 4 minutes.
NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates
present CO levels and responds accordingly. If CO levels remain poten-
tially dangerous—or start rising higher—the horn will start sounding
While the detector is silenced:
“ALARM-MOVE TO FRESH AIR”

move everyone to a source of fresh air.
