and cannot be shaken loose. If the batteries are
not snapped in completely, the unit cannot receive
battery power.
NOTE: After activating the battery, the power
indicator light may flash. (See Figure 3) If the
unit alarms, the light will blink rapidly, and
the horn will repeatedly sound three beeps,
pause, three beeps. Once the smoke/CO
detector is on the bracket, rotate it to adjust
the alignment.

LOCKING FEATURE (OPTIONAL)
1. The optional locking feature is designed to prevent
unauthorized removal of the detector. It is not
necessary to activate the lock in single-family
households where unauthorized detector removal is
not a concern.
2. The feature uses a locking pin, which is molded into
the mounting bracket. Remove locking pin by using
needle-nose pliers or a utility knife.
IMPORTANT! To permanently remove the
locking pin, insert a flathead screwdriver
between the locking pin and the lock and pry
the pin out of the lock.
