Which NEC code applies to fire alarm systems?

• A. Section 300.11
• B. Article 728
• C. Article 760
• D. All of the above

Answer: (D)

Fire alarm systems have a primary home in Article 760, which outlines the specific requirements for fire alarm and detection systems, including the components, wiring, power sources, supervision, and testing. But you also need to follow the general wiring methods rules in Section 300, since those apply to how conductors and raceways are installed for any electrical system, including fire alarms. In addition, signaling and related equipment used with fire alarm systems can be covered under other articles like Article 728, which addresses signaling systems and devices. Because a fire alarm installation combines the specialized fire-related provisions with general electrical standards and signaling components, all of these NEC parts are relevant. That’s why all of the above is the best answer.
