The Kidde AP-P adapter plate gives 302 and 302-AW rate compensation heat detector installs a clean, finished look on standard electrical boxes. Instead of surface-mounting the detector directly, the AP-P sits flush against the box and provides a decorative base that covers the rough opening.

Built for clean box-mount installs

The AP-P fits any 3" outlet box or 4" octagon outlet box, covering the two most common rough-in configurations in commercial fire alarm work. White plastic construction matches the 302 series detector housing for a consistent ceiling line.
