National Supply of Alcohol Gas Alarms

Operation Principle: The detectors installed on-site are powered by the controller. In the event of a gas leak, the RBK-6000-ZL9 type Combustible Gas Alarm Controller converts the leak amount into a corresponding voltage signal for output. The voltage signal is then processed by the detector and uploaded to the controller. Upon receiving the data, the controller decodes it and displays it on the screen. When the concentration reaches the set trigger value, the controller triggers an alarm and drives an external device.
