• Kidde alarms are not designed, agency tested or certified for recessed mounting and should not
be installed in this manner. Recessed mounting impedes smoke entry into the smoke chamber,
which may prevent the alarm from sounding in a timely manner. This could endanger the lives of
occupants in the residence. Kidde alarms are designed, tested and certified for wall (if applica-
ble) and ceiling surface mount only.
• After selecting the proper location for your alarm, attach the mounting bracket to the wall or
ceiling. To ensure aesthetic alignment of the alarm with the hallway, or wall, the “A” line on the
mounting bracket should be parallel with the hallway when ceiling mounted, or horizontal when
wall mounted. (Figures 9-D and 9-E)
• Install the alarm fully on the mounting bracket by rotating the alarm in a clockwise direction.
(Figure 9-C)
NOTE: The alarm will mount to the bracket in 4 positions (every 90 degrees).
NOTE: Installing the alarm on the mounting bracket will automatically activate the battery.
NOTE: The battery activation is a one-time feature that occurs when the red wheel is turned to the
“ON” position with a screwdriver, or when the alarm is rotated fully onto the mounting bracket. After
activation, the battery cannot be turned off, and can only be permanently discharged in the event of
a fatal fault or at the end of unit life. If the alarm is removed from the mounting plate, the battery will
remain active. See Permanently Disable Alarm / Discharge Battery section.
The alarm is now activated! After installation / activation, test your alarm as described in Operation and
Testing section.
WARNING: FAILURE TO PROPERLY INSTALL AND ACTIVATE THIS ALARM WILL
PREVENT PROPER OPERATION OF THIS ALARM AND WILL PREVENT ITS RESPONSE TO
FIRE AND CO HAZARDS.
