DMP Alarm Graphic Keypad - designed to work seamlessly with model 7872, and likely compatible with all similar DMP keypad models. J-Box Adapter - allows for easy mounting of the keypad to standard USA-style electric j-boxes. The adapter features holes and punchouts for single, double, triple-gang, and 4-square boxes. Surface Mount Backbox - same as above but taller, providing ample space to connect the wiring harness to field wiring inside the adapter. Wirmold/Metallic Raceway Backbox - same as above but even deeper, featuring a space to attach the box to metallic surface mount raceway entering from the top center. If you need a side or bottom entrance and lack the skills to modify Fusion 360 files yourself, let me know and I'll create one for you (fast service not guaranteed). Image attached shows which punchouts are for which purpose. To remove a punchout, simply stab the tip of a screwdriver through the appropriate slot and give it a wiggle. When attaching to a j-box, it's typical that various "gang" connectors use a #6 machine thread screw, while the 4-square screw should be a #8. For all variations, you can use longish #6 coarse thread screws provided by DMP with the keypad if you want, but they will stick out the back of the adapter unless you cut them shorter (or you're okay with them penetrating the surface behind). Alternatively, four #6 x 3/8" screws should be just about perfect, though you might have to blunt/snip the pointy tip when using the j-box adapter if you don't want the very tip sticking out the back. Use only #6 screws to attach keypad bracket to adapter. Using larger screws may short against circuit board.
