IntraSonic RETRO-MDAW RETRO MyDoor Adapter Plate
The Intrasonic RETRO-MDAW MyDoor Adapter Plate works with the Intrasonic RETRO-MyDoor. The adapter plate screws onto older Nutone, M&S, and Broan recessed speaker housings. The wiring from the master station to the door station connects to the adapter plate first. The RETRO MDAW adapter plate can then connect the Mydoor via the wiring and screwing in place.
