AHJ stands for what in alarm terminology?

• A. Alarm Handling Jurisdiction.
• B. Authority Having Jurisdiction.
• C. Architectural Hazard Judgment.
• D. Approved Home Jurisdiction.

Answer: (B)

AHJ stands for Authority Having Jurisdiction. This term refers to the official person or agency empowered by law to enforce codes, issue permits, and conduct inspections for alarm systems. In practice, the AHJ could be a city or county fire department, building department, or another local or state agency responsible for code compliance. Recognizing who the AHJ is matters because they determine whether an installation meets required standards, approve the permit, and authorize system activation after inspection. The other options aren’t standard terms used in alarm terminology, so they don’t describe the responsible authority.
