Single channel audio operation
Overview
This section describes the single channel and single channel plus paging audio systems. The term Single Channel Audio refers to the audio
capability of the system.
• A Single Channel Audio system has the ability to play pre-recorded messages or live audio messages, but it cannot do both at one
time. For example, suppose the building's audio system is divided into eight groups, each of which represents a floor of the building. A
single channel audio system can play a pre-recorded message or live audio one floor at a time.
