NFPA ______ has requirements for installation of elevator recall smoke detectors and their connection to a Fire Alarm System.

NFPA ______ has requirements for installation of elevator recall smoke detectors and their connection to a Fire Alarm System.

• A. 101
• B. 70
• C. 75
• D. 72

Answer: (D)

NFPA 72 governs the installation of fire alarm systems, including how detectors are wired and how they interface with the elevator recall function. Elevator recall relies on signals from the fire alarm system to bring elevators to a safe floor and restrict them during a fire event, so the code sections that specify detector placement, interconnections, supervision, power, and annunciation are all part of NFPA 72. Other standards don’t cover this specific integration of elevator recall with a fire alarm system in the same way: NFPA 101 focuses on life safety and egress without detailing fire alarm interconnections, NFPA 70 covers general electrical installation but not the fire alarm system design and signaling requirements, and NFPA 75 deals with IT equipment protection. Therefore, the appropriate standard is NFPA 72.
