Who has the final authority on fire alarm system installations?

The final authority on fire alarm system installations rests with the Authority Having Jurisdiction (AHJ). The AHJ is typically a fire marshal or other designated official who has the responsibility of enforcing building and fire codes within a specific area. They have the expertise to assess compliance with regulations and ensure that installations meet safety standards.

The AHJ's role includes reviewing plans, conducting inspections, and providing approvals for fire alarm installations. This ensures that the systems are not only compliant with local codes but also adequately protect the safety of building occupants and property. Their authority is derived from municipal codes and fire safety regulations, which they enforce to maintain public safety.

While the building owner and local fire department play significant roles in the process, it is ultimately the AHJ that has the final say in the acceptance of fire alarm systems. The fire alarm installer is responsible for implementing the installation according to the prescribed standards but does not hold the final authority regarding code compliance.
