This covers interface with elevators (recall), door holders (release for smoke control), and HVAC shutdown.
The primary goal of NFPA 72 is simple but profound: to ensure that fire alarm systems work as intended when a real emergency occurs. It accomplishes this by providing minimum levels of performance, reliability, and safety. The code covers everything from the placement of a single smoke detector in a one-family dwelling to the complex mass notification systems found in airports, stadiums, and high-rise buildings.
Modern code places heavy emphasis on visual signaling (strobe lights). NFPA 72 calculates the placement of strobes based on room size and "candela" ratings (light intensity). This ensures that individuals with hearing impairments are alerted just as effectively as those with full hearing.
