Under the authority having jurisdiction, who is responsible for inspecting fire alarm system installations?

The correct answer is that the Authority Having Jurisdiction (AHJ) is responsible for inspecting fire alarm system installations. This is because the AHJ is an entity or official designated by law or regulation to ensure compliance with applicable codes, standards, and regulations related to fire safety. Their role involves overseeing construction and installation projects to verify that they meet the required safety and operational standards.

The AHJ typically consists of local fire marshals, building inspectors, or other officials who have the authority to enforce building codes and safety regulations. They evaluate whether the installed systems adhere to the National Fire Protection Association (NFPA) codes and standards, as well as local ordinances.

While the other individuals mentioned, such as company owners, certified inspectors, or project managers, may play important roles in the process of designing, installing, or maintaining fire alarm systems, it is ultimately the AHJ that has the legal authority to conduct inspections and approve installations. This ensures that fire alarm systems are operational and safe for use, thereby protecting lives and property.
