Which component is responsible for emitting the audible alert in a burglar alarm system, as triggered by the control logic?

• A. Control Panel
• B. Sensor
• C. Siren
• D. Programmable sounding control unit

Answer: (C)

In a burglar alarm system, the audible alert is produced by the siren. The control logic watches the sensors and, when an intrusion is detected, sends a signal to activate the siren. The sensors are just detectors and don’t make sound, while a programmable sounding control unit may govern timing or patterns of the alert, the actual noise comes from the siren. The siren is the dedicated output device designed to emit the audible warning to occupants and deter the intruder.
