摘要： A signal distribution and communication arrangement controls the broadcast of different types of signals through speakers located in various zones. The arrangement includes an audio receiver circuit which responds to a music signal from an external music source, and an associated threshold detection circuit which provides a music mute function. Further, a page interface circuit, responds to a page signal generated from a telephone handset, which generates a paging control signal and serves as a power source to the telephone handset; and a doorbell interface circuit responds to any of a plurality of doorbell signal sources at differing locations by generating a doorbell control signal and activating a corresponding door bell tone sequence which identifies the location of the doorbell signal source. Finally, a control circuit, responds to these various circuits by selecting which of the corresponding signals should be broadcast by the speakers.

摘要： The invention provides a mounting frame structure for association with a preformed aperture in a wall and for recessed mounting of a speaker or camera having a housing. The frame structure includes a one-piece, unitary frame body having an open central region for receiving therethrough body portions of the housing. The frame body has a flattened perimeter region and apertures individually located in the perimeter region. The frame structure also includes a shoulder region upstanding rearwardly from and extending substantially about the perimeter region. A mounting flange upstands rearwardly in a perpendicular direction from the perimeter region. The mounting flange has a generally flat shape and at least one aperture therethrough so that the mounting flange abuts and secures to a stud or cross-member of the wall. Optionally, the frame structure is utilized in an assembly with a mounting bracket for the camera or speaker and a cover plate thereover.

摘要： A signal distribution and communication arrangement controls the broadcast of different types of signals through speakers located in various zones. The system includes a telephone interfaced with a door speaker controller to allow communication between the telephone and a door speaker. A page may be broadcast over the speakers and subsequently muted to allow private communication when the page is answered. Also included is a doorbell interface circuit that responds to a doorbell source. The doorbell source may be activated by any one of a plurality of doorbell switches.
