Which component of the fire alarm system is used to silence the alarm?

The control panel is a critical component of a fire alarm system, responsible for monitoring and managing the overall operation of the system. When an alarm is triggered, the control panel not only activates the alarm notification devices, such as sirens or strobe lights, but it also has the capability to silence the alarm when appropriate conditions are met. This might occur after the situation has been assessed and it has been confirmed that there is no ongoing fire threat, allowing personnel to reset the system and return to a normal state.

In contrast, the other components serve different functions: remote annunciators typically provide status updates or alerts from different locations, alarm initiation devices are responsible for detecting a fire (like smoke detectors or pull stations), and alarm notification devices are designed to alert occupants of the building to evacuate or take action in response to a fire alarm.
