First Alert SA302 - Manual (Page 2)

Do not install this Smoke Alarm in a location where it could be easily
triggered when using your remote to operate your TV, VCR, or other
remote controlled appliances.
If you want to lock the battery drawer, or lock the Smoke Alarm to
the mounting bracket, please read the “Optional Locking Features”
section before you begin installation.
1. Hold base firmly and twist the mounting bracket clockwise to separate
it from the base.
2. Hold the mounting bracket against the ceiling (or wall) so the vertical
mounting slot is aligned in the 12 o’clock position and trace around
the inside of the mounting slots (vertical and horizontal mounting).
3. Put the unit where it won’t get covered with dust when you drill the
mounting holes.
4. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the
oval outlines you traced.
5. Insert the plastic screw anchors (in the plastic bag with screws) into
the holes. Tap the screw anchors gently with a hammer, if necessary,
until they are flush with the ceiling or wall.
6. Attach the mounting bracket to the ceiling or wall.
7. Install the battery (included) so the terminals on the battery match
the terminals on the Smoke Alarm. Match “+” to “+” and “-” to “-.”
Push the battery in until it snaps in securely and cannot be shaken
loose. If the battery is not snapped in completely, the unit cannot
receive battery power.
NOTE: After you install the battery, the power indicator light will
flash and the horn will chirp. (If the unit alarms, the light will blink
rapidly, and the horn will repeatedly sound 3 beeps, pause, 3 beeps.)
8. Attach the Smoke Alarm to the bracket. Line up the guides on the
alarm’s base with the guides on the mounting bracket. When guides
are lined up, turn the base clockwise (right) until it snaps into place.
NOTE: Once the Smoke Alarm is snapped onto the bracket, you
can rotate the cover to adjust the alignment.
9. Test the Smoke Alarm. See “Weekly Testing.”

OPTIONAL LOCKING FEATURES
The locking features are designed to discourage 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. Depending on which locking features
you use, remove one or both pins from the mounting bracket using needle nose pliers or a utility knife.
To permanently remove either lock, insert a flathead screwdriver between the locking pin and the lock, and pry the
pin out of the lock.
