During testing of manual fire alarm boxes, the protective covers emit a local alarm signal. According to the IBC, what is required?

In the context of testing manual fire alarm boxes and their protective covers emitting a local alarm signal, the correct answer pertains to the requirement for approval from the Authority Having Jurisdiction (AHJ). The AHJ is responsible for approving installation and testing procedures, which includes ensuring that systems meet necessary safety standards and local codes.

When manual fire alarm boxes are tested, and especially when modifications such as protective covers that trigger an alarm are involved, it is vital to have the AHJ's approval to confirm compliance with local regulations and fire codes. This oversight ensures that all fire protection measures are effectively integrated and that they function correctly during an actual fire emergency.

While the other options may address different considerations regarding fire alarm systems, they do not directly relate to the specific requirement outlined in the question regarding the testing of manual fire alarm boxes and the necessity for AHJ approval in this context.
