NFPA 72 Mass Notification Regulations

The National Fire Protection Association mandates that within public acoustically distinguishable spaces (ADS) where voice communication systems are required, the system can reproduce pre-recorded, synthesized, or live messages with voice intelligibility. Meeting NFPA’s criteria requires careful design, especially for facilities with acoustically dissimilar spaces, like mass transit, healthcare, higher education, and convention centers. A case study describes the process of achieving voice intelligibility in ADS from preliminary design to final testing.

NFPA 72 Fire Alarm Code: Mass Notification System Design Overview

With the release of NFPA 72-2010, opportunities for mass notification technology have increased. Today, alarm and mass notification systems must provide threat-specific verbal guidance and instruction for a variety of threats and hazards, not only within a building, but also outdoors (across a campus for example). Learn about the main components of a mass notification system: identifying acoustically distinguishable spaces, audio system and data network design including fault-tolerance, redundancy and survivability, high-power speaker areas and voice intelligibility testing.
