How To Install This Smoke 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” smoke alarms before you
begin installation. If a junction box is not already in
place, install one using standard #12 or #14 gauge
solid copper Appliance Wiring Material.
IMPORTANT!
Activate the battery back-up by removing the “Pull
to Activate Battery Back-Up” tab. You do not need
to open the battery compartment and reposition the
battery during installation.
When the battery is activated, the red light will
shine continuously for 5-10 seconds, then begin
to flash about once a minute.
Test the battery back-up. Press and hold the test
button on the cover until the alarm sounds.
