It covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, emergency communication systems (ECS), and their components.

If you are an electrical engineer, a building contractor, a fire marshal, or a facility manager, understanding NFPA 72 is not optional—it is mandatory. This code dictates how fire alarm systems are designed, installed, tested, maintained, and monitored. Failing to comply with NFPA 72 doesn't just risk code violations; it risks lives.
