IMPORTANT INSTALLATION PARTS
The Mounting Bracket:
To remove the mounting
bracket from the Smoke
Alarm base, hold the
Smoke Alarm base firmly
and twist the mounting
bracket off. The mounting
bracket installs onto the
junction box. It has a
variety of screw slots to
fit most boxes.
The Power Connector: The power
connector plugs into a power input
block on the Smoke Alarm. It supplies
the unit with AC power.
• The black wire is “hot.”
• The white wire is neutral.
• The orange wire is used for
interconnect.
If you need to remove the power
connector, insert a flat screwdriver blade
between the power connector and the
security tab inside the power input
block. Gently pry back the tab and pull
the connector free.
LOCKING FEATURES
The locking features are designed to prevent
unauthorized removal of the battery or alarm. It is
not necessary to activate the locks in single-family
households where unauthorized battery or alarm
removal is not a concern.
These Smoke Alarms have two separate locking
features: one to lock the battery compartment, and
the other to lock the Smoke Alarm to the mounting
bracket. You can choose to use either feature
independently, or use them both.
Tools you will need:
• Needle-nose pliers or utility knife
• Standard/Flathead screwdriver.
Both locking features use
locking pins, which are
molded into the mounting
bracket. Using needle nose
pliers or a utility knife,
remove one or both pins
from the mounting bracket,
depending on how many
locking features you want
to use.
To permanently remove either lock insert a flat-
head screwdriver between the locking pin and the
lock, and pry the pin out of the lock.
