Which NFPA standard governs elevator recall smoke detectors and their connection to a Fire Alarm System?

Which NFPA standard governs elevator recall smoke detectors and their connection to a Fire Alarm System?

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

Answer: (C)

The key idea is which standard specifically governs how fire alarm systems are installed and how their components, like smoke detectors, interconnect with other life-safety functions such as elevator recall. NFPA 72, the National Fire Alarm and Signaling Code, covers the design, installation, testing, and operation of fire alarm systems. It defines how smoke detectors act as initiating devices, how they wire into the Fire Alarm Control Panel, and how the system interfaces with other building systems, including elevator recall so elevators respond appropriately during a fire event. NFPA 70 addresses electrical installations and safety, but not the fire alarm system design details. NFPA 13 covers sprinkler installations, not fire alarm signaling. NFPA 101 focuses on life safety requirements and egress, but the specific standards for fire alarm system components and their integration are in NFPA 72.
