Which statement best describes the annunciator's primary function?

• A. It records video from cameras.
• B. It provides remote access.
• C. It lists alarm zones with visual lights or audible indicators to identify a tripped sensor.
• D. It stores user codes.

Answer: (C)

An annunciator is a local signaling panel that shows the status of each alarm zone using lights or sounds. When a sensor is tripped, the annunciator highlights the specific zone, allowing an operator or responder to quickly identify exactly where the event occurred and respond appropriately. This immediate, on-site indication is its primary purpose, helping with fast verification and action. Video recording is handled by cameras and recording equipment, not by the annunciator. Remote access is provided by network interfaces or specialized software, not by the annunciator itself. Storing user codes is a function of access control devices or keypads, not the annunciator.
