Abstract

A distributed intercom system (10) including a centralized interconnection unit (12) with a central control device (14) for receiving, processing and transmitting signals, a power distribution device (16) for transmitting a power signal (18) for distribution and at least one cable connection port (20) for receiving a cable connection therein. The system (10) includes a cable (22) with a cable connection element (24) for connection to the cable connection port (20), and the cable (22) transmits a control signal (26), a line-level, analog audio signal (28) and the power signal (18). One or more remote user interface units (30) are connected to and in communication with the centralized interconnection unit (12) through the cable (22), and the remote user interface unit (30) includes an amplifier (32), a speaker device (34) and a microphone device (36). At least one component of the remote user interface unit (30) is powered by the power signal (18) transmitted by the power distribution device (16).
