Changes in the National Fire Alarm Code will affect the way occupant notification systems are used and designed. More emphasis has been placed on Emergency Voice Communication Systems, especially Mass Notification Systems (MNS).

The application of voice systems for multi-hazard use will expand your capability to market and sell these higher-end systems. To increase your market share in this area there are some things that you need to know to stay out of trouble and remain profitable.

This session looks at the difference in a system using horns for audible signaling and the use of speakers for voice notification. Sound levels and speech intelligibility are discussed, as well as the difference in layout design for speakers, wiring for survivability and system message priority.
