Power supplies for fire alarm systems must be installed in accordance with which code?

• A. NFPA 70
• B. NFPA 72
• C. NFPA 101
• D. NFPA 13

Answer: (A)

The main idea is that electrical power for fire alarm systems is governed by the National Electrical Code. The NEC sets the rules for wiring methods, conductor sizing, overcurrent protection, enclosures, mounting, grounding, and other safety requirements for electrical power supplies and related equipment. NFPA 72 deals with how fire alarm systems operate and signal, but it does not prescribe general electrical installation methods—that role belongs to NFPA 70. NFPA 101 covers life-safety requirements at a higher level, and NFPA 13 is about sprinkler systems. So power supplies must be installed in accordance with NFPA 70 to ensure safe and reliable electrical installations.
