A duo LED, which lights up green when the system is ready for operation, serves as an operating indicator. Detection is performed by a combination of a smoke detector and a Line-heat-detection cable. As soon as one of the two detection lines triggers an alarm, the alarm message is displayed on the controller. At the same time, the Duo-LED changes its color to red and the horn sounds. If the second detection line also reports an alarm, the flashing light is activated, and the extinguishing generator is triggered immediately.
