Special hazard systems are tested to demonstrate proper operation per NFPA 72 requirements. At which point in the testing process is the AHJ notified?

• A. Prior to the initial acceptance test
• B. During the test
• C. After the initial acceptance test
• D. Only after issues are found

Answer: (A)

The key point is that acceptance testing for special hazard fire alarm systems must be witnessed by the Authority Having Jurisdiction (AHJ). NFPA 72 requires inviting or notifying the AHJ before the initial acceptance test so they can attend and observe the test to verify proper operation and compliance with design, codes, and standards. This early notification ensures regulatory oversight, allows the AHJ to witness critical checks, and helps catch any issues before the test is completed. If you wait to notify during the test, after the test, or only after issues are found, you’d miss the opportunity for the AHJ to observe the test in real time and verify that the system meets requirements from the outset. Therefore, notifying the AHJ prior to the initial acceptance test is the correct protocol.
