Mounting

CAUTION: This unit is sealed. The cover is not removable.
• To help identify the date to replace the unit, a label has
been affixed to the side of the alarm. Write the "Replace
by" date (10 years from power up) in permanent marker
on the label. See Alarm Replacement section for
additional information.
• Remove the mounting plate from the back of the alarm
by holding the mounting plate and twisting the alarm in
the direction indicated by the "OFF" arrow on the alarm
cover.
• After selecting the proper Smoke/CO alarm location as
described on Pages 8-10, and wiring the AC Quick-
Connect wire harness as described in Wiring, attach the
mounting plate to the electrical box. To ensure
aesthetic alignment of the alarm with the hallway, or
wall, the "A" line on the mounting plate must be
parallel with the hallway when ceiling mounted, or
horizontal when wall mounted.
• Pull the AC Quick-Connect wire harness through the
center hole in the mounting bracket and secure the
bracket, making sure that the mounting screws are
positioned in the small ends of the keyholes before
tightening.

• Plug the AC Quick-Connect wire harness into the back
of the alarm (see Figure 2), making sure that the locks on
the connector snap into place. Push the excess wire back
into the electrical box through the hole in the center of
the mounting plate.
