Which standard governs the detector spacing and testing referenced in these questions?

• A. NFPA 13
• B. NFPA 72
• C. NFPA 70
• D. NFPA 101

Answer: (B)

Detector spacing and testing for fire alarm systems are governed by NFPA 72, the National Fire Alarm and Signaling Code. This standard specifies how fire alarm systems should be designed, installed, tested, and maintained, including guidelines for detector placement to ensure effective coverage and the procedures and frequencies used to verify system operation. NFPA 13 covers sprinkler systems, NFPA 70 is the National Electrical Code for electrical wiring and installations, and NFPA 101 (Life Safety Code) focuses on egress and occupancy life-safety requirements.
