NFPA 72 is the standard most closely associated with which of the following systems?

• A. Fire alarm signaling
• B. Electrical wiring guidelines
• C. Building accessibility
• D. Fire suppression systems

Answer: (A)

NFPA 72 governs fire alarm signaling and the related life-safety notification systems. It outlines how fire alarm systems should be designed, installed, tested, and maintained, including the components like initiators (smoke/heat detectors, pull stations), control panels, notification appliances (sirens, horns, strobes), power supplies, and how signals are communicated to occupants or central stations. This code specifically handles how alarms are triggered, supervised, and coordinated for effective warning and evacuation.

Electrical wiring guidelines are covered by the National Electrical Code, not NFPA 72. Building accessibility is governed by accessibility standards, such as those in the ADA. Fire suppression systems are covered by codes like NFPA 13 and related standards. So the system most closely associated with NFPA 72 is fire alarm signaling.
