MOUNTING INSTRUCTIONS
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
1. Remove the trim ring from the back of the alarm by holding the
trim ring and twisting the alarm in the direction indicated by the
“OFF” arrow on the alarm cover.
2. After selecting the proper smoke alarm location as described
in section 1 and wiring the AC QUICK CONNECT harness as
described in the WIRING INSTRUCTIONS, attach the trim ring to
the electrical box (see figure 5).
3. Use a screwdriver to punch out only the pair of holes in the trim
ring that match your type of electrical box or plaster ring. Mount
the trim ring to the electrical box, using the appropriate holes.
NOTE: Use the circle, square and octagon markings near each
mounting hole in the trim ring to help you select the correct
mounting holes (see figure 5).
4. Pull the AC QUICK CONNECTOR through the center hole in the
trim ring and mount the ring, making sure that the mounting
screws are positioned in the small ends of the keyholes before
tightening the screws (see figure 5).
5. Plug the AC QUICK CONNECTOR into the back of the alarm (see
figure 6), making sure that the locks on the connector snap into
place. Then push the excess wire back into the electrical box
through the hole in the center of the trim ring.
6. If you have finished all the WIRING, BATTERY INSTALLATION AND
TRIM RING MOUNTING STEPS, you can install the alarm on the
trim ring. Alignment marks are provided on the side of the alarm
and on the trim ring (see figure 7).
7. Install the alarm on the trim ring with the indicating marks
aligned and rotate the alarm in the direction of the “ON” arrow
on the cover until the alarm snaps in place (see figure 7).
