What is the purpose of NFPA 72 in a fire alarm system?

• A. NFPA 72 is the national standard for fire alarm and signaling systems, covering design, installation, testing, inspection, and maintenance to protect life and property.
• B. It governs only suppression systems.
• C. NFPA 72 is the standard for electrical power distribution in buildings.
• D. NFPA 72 is a local code published by city fire departments.

Answer: (A)

NFPA 72 is the national standard for fire alarm and signaling systems, prescribing the design, installation, testing, inspection, and maintenance requirements to protect life and property. It covers how detectors, initiators, control panels, notification devices, power supplies, and communications must work together and sets performance criteria to ensure reliable detection and timely warning. By providing uniform criteria, it helps ensure fire alarm systems function consistently across buildings and jurisdictions. It’s not about suppression equipment or electrical power distribution, and it isn’t a local city code—the standard is published by NFPA and is often adopted by authorities having jurisdiction.
