HOW TO INSTALL
YOUR CO ALARM
This unit is designed to be mounted on any
standard wiring junction box up to a 4-inch
diagonal size, on either the ceiling or wall. Read
“Where to Install” and “Where Not To Install” CO
alarms before you begin installation. If a junction
box is not already in place, install one using
standard #12 or #14 gauge copper wire.
WARNING!
This alarm must have AC or battery power
to operate. If the AC power fails, the battery
back-up will power the alarm if the 9V battery
is fresh and correctly installed. If AC power
fails, and the battery is dead or missing, the
alarm cannot operate.
Before you begin 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 technician.
Place one label near the CO alarm, and the
other label in the “fresh air” location you
plan to go if the alarm sounds.
