ABSTRACT:
There is provided an audio communication system for a life safety system. The audio communication system includes an audio data line having a plurality of audio channels for transmitting audio data and a CPU for controlling the transmission of the audio data along the audio data line. An audio source module and an audio amplifier module are coupled to the audio data line. To produce an audible sound, the CPU selects a particular channel of the plurality of audio channels for transmitting the audio data and sends this selection to the audio source module. The audio source module then places one or more audio packets, corresponding to the audible sound, on the selected channel. The audio amplifier module then receives a signal from the CPU that identifies the selected channel and, thus, the audio amplifier module will know which channel to find the audio packets. The audio packets are converted and directed to speakers to produce the audible sound.
