Abstract
A broadcast system for a facility including audio and video signal generators that may also include the audio output of a microphone for forming broadcast signals. The broadcast signals include a program signal, a supervisory program signal and a supervisory alert signal. The power supply for monitoring stations and broadcast signals are combined to form an output signal that is broadcasted throughout the facility. A bus distributes the output signal in the facility to each of a plurality of monitor stations. Each monitor station includes decoders to recover the audio and video signals and form a resident power supply for that monitor station only from the output signal on the bus. The monitor could also includes a video monitor and speaker coupled to the resident amplifier to the resident power supply for responding to any of the broadcast signals. A resident controller controls the resident amplifier when receiving a program signal supplied to the monitor. A resident executive controller disables the resident controller and applies a recovered supervisory alert signal and supervisory program signal to the resident amplifier.
