Audio distribution system having programmable zoning features
First Claim
1. An electronically controlled signal routing network as part of an audio intercom system having a door-speaker zone and designated signal zones in a facility, each zone representing an area in the facility in which audio signals are broadcasted, the network comprising:
- a plurality of signal generating devices, each said signal generating device generating a signal for broadcast over the intercom system independently of the other signal generating devices;
a door-speaker arrangement located in the door-speaker zone and configured to couple control signals and audio signals within the intercom system between the door-speaker zone and the plurality of signal generating devices;
a receiving circuit, arranged to operate independently with respect to the plurality of signal generating devices, receiving user input information to designate a plurality of zones in which to route at least one of said respectively generated signals between the door-speaker zone and the plurality of signal generating devices for broadcast over the intercom system; and
an electronic control circuit includinga routing circuit for routing the signals respectively generated by said signal generating devices between a plurality of the signal zones and the door-speaker zone, anda programmable controller, responsive to the user input information received by the receiving circuit, for establishing and storing a routing path through the routing circuit;
said electronic control circuit routing at least one of the plurality of signals to the plurality of zones and the door-speaker arrangement as designated by the user for broadcast therein over the intercom system according to the established and stored routing path.

Abstract
A signal distribution and communication arrangement includes an electronic processor-based master control unit which 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 now be broadcast over selected speakers and zones selectively 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. An additional aspect of the present invention includes grouping zones together so that all source selection works concurrently, and each subzone in the group retains independent volume control, bass and treble. Further, a new sub-set of zone programming allows the installer to label a zone as any alpha-numeric seven-digit name.
