Which of the following is NOT a step in restoring fire alarm systems?

The correct choice indicates that activating all alarms is not a standard step in restoring fire alarm systems. In the context of fire alarm systems, restoration typically involves returning the system to a normal operational state after an incident. This process often includes actions such as resetting the alarm, documenting the response person's name for accountability and records, and notifying relevant parties like the responsible party and dispatch about the current status of the alarm system.

Activating all alarms, on the other hand, does not play a role in the restoration process. Instead, it could potentially cause confusion or create unnecessary alarm conditions, leading to further complications. The focus during restoration should be on ensuring that the system is reset and functioning properly without igniting more alarms unless there's a specific operational need for that.
