NFPA 72 pertains to which aspect of fire alarm systems?

• A. Fire alarm signaling
• B. Building electrical codes
• C. Fire suppression systems
• D. Emergency lighting

Answer: (A)

NFPA 72 is the standard for fire alarm signaling. It defines how a fire alarm system should initiate, transmit, and announce alarms, including the devices that trigger signals (like smoke detectors and pull stations), the control panels that process those signals, and the audible and visual notification that occupants receive. It also covers monitoring and supervision of circuits, pathways to central stations, and the testing and maintenance required to keep the signaling functions reliable. This focus on how alarms are signaled and communicated distinguishes it from other areas like building electrical codes (wiring and safety standards), fire suppression system standards (extinguishing systems), or emergency lighting standards (egress illumination governed by other codes).
