What is the role of the AHJ in fire alarm system installation and testing?

• A. The AHJ enforces codes, issues permits, and performs inspections to ensure compliance.
• B. The AHJ designs the system layout.
• C. The AHJ handles all maintenance after occupancy.
• D. The AHJ is responsible for manufacturing devices.

Answer: (A)

The role of the AHJ is to ensure fire alarm work meets codes and standards by reviewing plans, issuing permits, and conducting inspections to verify proper installation and testing. They review design documents against applicable codes (such as NFPA 72 and local amendments), authorize the work with a permit, and then inspect or witness testing to confirm everything is installed correctly, labeled, and operable before approval for occupancy. The AHJ may also require commissioning, documentation, and as-built drawings to be submitted.

This isn’t about designing the system layout, which is the responsibility of the qualified designer or contractor under code rules. It isn’t about handling all maintenance after occupancy, which is typically done by the building owner or a licensed service provider, albeit with periodic AHJ inspections or acceptance testing as required. And it isn’t about manufacturing devices—the hardware comes from manufacturers and is installed by the contractor.
