How do manufacturer published instructions relate to NFPA 72 requirements for electric automatic detection?

• A. True
• B. False
• C. Only if AHJ approves
• D. Only for certain devices

Answer: (A)

Manufacturers publish installation instructions for their detectors because those guidelines reflect how the device was tested, listed, and wired to work reliably within a system. NFPA 72 requires that electric automatic detectors be installed and tested in accordance with the listing and the manufacturer’s published instructions, ensuring proper mounting, spacing, wiring, power supply, sensitivity, testing procedures, and compatibility with the signaling system. The AHJ may review and approve changes, but the baseline requirement is to follow the manufacturer’s instructions; it isn’t limited to only certain devices or conditioned on AHJ approval. This ensures the device performs as intended and maintains fire alarm system integrity.
