What is required by NFPA 72 concerning the function of associated equipment?

• A. Testing personnel are required to be experienced and qualified.
• B. Testing personnel must be licensed electricians only.
• C. Testing personnel must have at least 5 years in fire protection.
• D. Testing personnel may be unqualified if supervised.

Answer: (A)

Testing and maintenance of associated equipment must be performed by individuals who are experienced and qualified. NFPA 72 requires those conducting tests to be competent to verify that all components of the fire alarm system—sensors, activation devices, control panels, power supplies, and signaling devices—operate correctly and interact as intended so the system will respond properly in a fire. This focus on qualification ensures testers can interpret device behavior, safely manage power and wiring, and identify faults that could affect reliability. The standard does not mandate a specific license type such as licensed electricians, nor a fixed years-at-fire-protection requirement. Supervision of an unqualified person does not meet the requirement, since the standard expects the person performing testing to be qualified.
