Who is responsible for conducting or witnessing an acceptance test of the complete emergency system?

The authority having jurisdiction is responsible for conducting or witnessing an acceptance test of the complete emergency system. This ensures that installations comply with the applicable codes, standards, and regulations established by the governing bodies. The authority's involvement is crucial because they have the expertise and mandate to verify that the installation meets safety and operational requirements before the system becomes operational.

The acceptance test is a critical step in the commissioning process of emergency systems. It serves to confirm that all components are functioning properly and that the system can perform as expected in an emergency situation. This oversight provides an additional layer of safety for the building occupants and emergency responders.

While the building owner may have a vested interest in the performance of the emergency system, and the electrical contractor may perform the installation, it is the authority having jurisdiction that has the responsibility to ensure compliance through witnessing or conducting tests. The electrical inspector also plays a role in ensuring safety and code compliance, but in this specific context, the acceptance testing is primarily linked to the authority assigned the responsibility by law or regulation.
