IMPORTANT! At end of life or low battery
indication (chirp), unit must be put into

remounting.
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.

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.
