An emergency voice/alarm communications system is designed to provide a highly reliable voice
reinforcement and distribution network. These systems must deliver messages to building
occupants for evacuation in an organized and safe manner. The system can deliver recorded
messages automatically before emergency personnel arrive at the scene, and alarm paging systems
can also be used to deliver live spoken messages from the emergency personnel to the occupants.
