Which standard governs audible and visible notification appliances?

• A. NFPA 70
• B. NFPA 101
• C. NFPA 72
• D. NFPA 90A

Answer: (C)

Audible and visible notification appliances are addressed by the fire alarm signaling standard. NFPA 72, the National Fire Alarm and Signaling Code, sets the requirements for the design, installation, performance, testing, and maintenance of fire alarm systems, including the devices that alert occupants with sound (horns, bells, chimes) and with light (strobes and other visual signaling). It covers how these devices should operate, where they should be placed, the required sound levels and visibility, synchronization for visual alerts, and how they integrate with the overall alarm system. Other standards focus on different areas: NFPA 70 covers electrical installations, NFPA 101 is the Life Safety Code that governs overall occupancy safety and egress but references NFPA 72 for alarm systems, and NFPA 90A deals with the installation of HVAC systems.
