Which code governs the installation and maintenance of fire alarm systems?

The installation and maintenance of fire alarm systems is primarily governed by NFPA 72, known as the National Fire Alarm and Signaling Code. This code specifically addresses the design, installation, and maintenance criteria for fire alarm systems, ensuring that they perform effectively to alert occupants in case of a fire. NFPA 72 lays out the standards for detection, notification, and alarm systems, ensuring safety and reliability in fire alarm operations.

Each section of NFPA 72 provides detailed guidelines, including requirements for various types of alarm systems, equipment compatibility, and testing procedures. This makes it the central reference for professionals in the field responsible for the proper functioning of fire alarm systems.

In contrast, NFPA 70 focuses on the National Electrical Code (NEC), which primarily covers electrical wiring and installations but does not specifically address fire alarm systems. NFPA 101, known as the Life Safety Code, deals broadly with means of egress and occupant safety in buildings, while NFPA 10 pertains to portable fire extinguishers. Thus, NFPA 72 is the most relevant code for fire alarm system installation and maintenance.
