Which NEC Article covers Fire Alarm Systems?

Which NEC Article covers Fire Alarm Systems?

• A. NEC Article 725
• B. NEC Article 770
• C. NEC Article 760
• D. NEC Article 800

Answer: (C)

Fire alarm systems are treated as a specialized life-safety electrical installation, so the NEC has a dedicated article for them. This article lays out how fire alarm circuits are powered and supervised, the types of circuits involved (signaling and notification appliance circuits), and how devices such as detectors, pull stations, horns, and strobes, along with control panels and remote annunciators, must be wired and protected. It also specifies power source requirements (primary and secondary), wiring methods, separation from other circuits, and labeling to ensure reliability and safe operation, all in harmony with NFPA 72 for performance. The other articles cover different topics—low-voltage Class 2/3 circuits, optical communications, or general communications wiring—so they don’t address the specific needs of fire alarm systems.
