Who has the final authority on fire alarm system installations?

The correct answer is the Authority Having Jurisdiction (AHJ) because the AHJ is responsible for interpreting and enforcing codes, standards, and regulations related to fire safety and alarm systems. This includes overseeing the installation of fire alarm systems to ensure they meet the required local, state, and national standards. The AHJ may consist of fire marshals or other officials designated by the local government to ensure compliance with safety practices.

The role of the AHJ is critical in maintaining public safety, as they have the expertise to evaluate whether installations meet safety criteria, thereby preventing potential hazards associated with improperly installed fire alarm systems. Building owners and fire alarm installers are key stakeholders in the process, but they do not possess the final authority; rather, they must work in compliance with the rules set forth by the AHJ.
