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.
