The location of the alarm control is at the discretion of which authority?

The authority responsible for determining the location of the alarm control is known as the Authority Having Jurisdiction (AHJ). This designation refers to the individual or organization that has the legal authority to enforce codes and regulations within a specific jurisdiction. The AHJ is often tasked with interpreting the intent of the codes and ensuring compliance with safety regulations.

In practical terms, this means that the AHJ considers various factors such as local building codes, safety standards, the layout of the building, and the specific needs for effective alarm response when deciding on alarm system installations, including the location of control panels. Their role is essential to ensure that alarm systems are positioned in a way that maximizes safety and efficiency for emergency responders.

The other options do represent important roles in the overall framework of fire safety and compliance, but they do not have the same level of authority in deciding the specifics of alarm control location as the AHJ.
