Which standard is primarily associated with fire alarm systems?

• A. NEC
• B. NFPA 72
• C. NFPA 13
• D. ISO 9001

Answer: (B)

NFPA 72, the National Fire Alarm and Signaling Code, is the standard that focuses specifically on fire alarm systems. It outlines how fire alarm systems should be designed, installed, tested, and maintained, including detection devices, notification appliances, control panels, and power supplies, plus the procedures for verification and ongoing maintenance. That direct scope is why it’s the best match for a question about standards related to fire alarm systems.

The NEC (National Electrical Code) governs electrical wiring and installations more broadly, not the detailed performance and testing requirements of fire alarm systems. NFPA 13 covers the layout and installation of sprinkler systems, not alarms. ISO 9001 is a quality management standard, unrelated to fire protection system design or operation.
