HOW TO INSTALL THIS SMOKE ALARM
THE PARTS OF THIS SMOKE ALARM
FOLLOW THESE SIMPLE STEPS!
This unit is designed to be mounted on the
ceiling, or on the wall if necessary.
Tools you will need:
• Pencil
• Drill with 3/16” (5 mm) drill bit
• Standard/Flathead screwdriver
• Hammer
1. Hold base firmly and pull up on cover tab
marked “OPEN HERE.” This will open the
hinged cover. The cover may unsnap from
the base if it's opened too far. This will not
damage the unit—the cover hinge snaps
back into place easily.
2. Hold the Smoke Alarm base against the
ceiling (or wall) and make a mark at the
center of each of the mounting slots with
a pencil.
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 each pencil mark.
5. Insert the plastic screw anchors (in the
plastic bag with screws) into the holes.
Tap the screw anchors gently with a ham-
mer, if necessary, until they are flush with
the ceiling or wall.
6. Tighten the screws (provided) into the
screw anchors, then loosen them two
turns.

7. Fit the Smoke Alarm over the screw heads
as shown. Close cover.
8. If the Smoke Alarm cover does not line up
the way you want it, rotate the base and
re-tighten the screws.
9. Activate the battery. With the cover open,
remove and reinstall the battery so the ter-
minals 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. The
Smoke Alarm may beep briefly when you
install the battery—this is normal.
Model SA150B has two batteries—
one powers the alarm, the other powers
the Escape Light®. You must reposition
BOTH batteries. The Escape Light®
requires an alkaline battery.
10. Close the cover all the way.
11. Test the Smoke Alarm. See “Weekly
Testing.”
