What is one of the requirements for using fire alarm systems with multiple detectors?

The use of fire alarm systems with multiple detectors includes specific requirements to ensure their effectiveness and compliance with regulations. One key requirement is that the systems must not be prohibited by authorities having jurisdiction (AHJ). This is essential because local codes and regulations can vary significantly, and they often reflect the unique safety needs and risks associated with different types of buildings and occupancy types.

Authorities having jurisdiction have the final say in determining what systems can be installed and used in their area, based on safety codes, fire protection needs, and local risk factors. If a fire alarm system with multiple detectors is prohibited by the AHJ, it means that it does not meet the local safety criteria or may not be suited to the specific environment in which it is to be installed. Therefore, adherence to AHJ regulations is crucial for the successful implementation of fire alarm systems with multiple detectors.
