Which NFPA standard governs fire alarm systems?

• A. NFPA 72
• B. NFPA 13
• C. NFPA 101
• D. NFPA 25

Answer: (A)

NFPA 72 is the standard that governs fire alarm systems. It specifies the design, installation, testing, and maintenance requirements for fire alarm and signaling systems, including detection, annunciation, alarm notification, supervisory signals, and emergency communication. This standard ensures fire alarms operate reliably, coordinate with building systems, and can be tested and maintained consistently. In contrast, NFPA 13 covers sprinkler system design and installation, NFPA 101 (Life Safety Code) addresses overall building life-safety requirements, and NFPA 25 covers inspection and maintenance of water-based sprinkler systems. So NFPA 72 is the governing standard for fire alarm systems.
