Which device indicates the location of the activated fire alarm device in a building?

• A. Alarm Control Unit
• B. Fire Alarm Bell
• C. Smoke Detector
• D. Annunciator Panel

Answer: (D)

The annunciator panel is designed to show exactly where an alarm originated. It maps the building into zones and lights or displays the specific zone or device that tripped, so occupants and responders know where to go or inspect first. This visual cue speeds locating the source of the alarm and coordinating an appropriate response. The Alarm Control Unit is the system’s central brain that monitors and logs events, but it isn’t the primary device used to show location to people in the building. A Fire Alarm Bell only sounds to alert, without pinpointing a location. A Smoke Detector senses smoke, but does not indicate where in the building the alarm came from.
