Which actions are typically performed by the Authority Having Jurisdiction (AHJ) during NFPA 20 compliance?

• A. Reviews plans
• B. Witnesses tests
• C. Approves installation based on code compliance
• D. All of the above

Answer: (D)

The AHJ’s role in NFPA 20 compliance centers on verification and authorization to ensure the fire pump installation meets code and safety requirements. They typically review the project plans to confirm the design, sizing, location, electrical supply, and integration with the overall system comply with NFPA 20 and relevant codes. They also commonly witness key tests to verify that the pump, its controls, and the associated systems perform as intended under specified conditions, including start sequences, priming, and pressure maintenance. After reviewing documentation and test results, the AHJ approves the installation for operation, certifying that it meets all code requirements and permit conditions. Since plan review, test witnessing, and final approval are all standard AHJ activities, all of these actions together describe what the AHJ typically does.
