The Model DMC1FB Combination Mounting Frame (Black) is used in new and retrofit intercom installations. The frame is designed to fit a DMC1B or DMC3-4B Music/Communication System Master when installed with the DMC1MM iPlay® Dock, DMCMP3B CD/MP3 player, or DMCBTB Bluetooth streaming player.
In new installations, use the DMC1F combination frame when installing a DMC1B with a DMC1MM, DMCMP3B or DMCBT below the master.
In retrofit installations, use the DMC1F combination frame when replacing a master only system with a DMC3-4B or DMC1B and a DMC1MM, DMCMP3B or DMCBTB below the master. NOTE: The wall hole will need to be enlarged for this type of retrofit installation.
