1. Connect to AC220V power, all indicator lights of the detector light up, accompanied by a buzzer bi, then enter the preheating state, all indicator lights flash continuously, and after 180 seconds, the red and yellow indicator lights go out and enter the normal monitoring state. In the preheating state, double-click the "self-test" button to exit the preheating state immediately.
2. In the normal monitoring state, when the detector detects that the concentration of combustible gas in the air reaches the alarm setting value, the detector enters the alarm state, sends out an audible and visual alarm signal, and the red indicator light flashes quickly. After 1 second, the control output interface outputs an action signal. When the concentration of combustible gas in the air is detected to be lower than the alarm setting value, the red indicator light goes out and returns to the normal monitoring state.
3. In the normal monitoring state, short press the "self-test" button to enter the self-test state, all indicator lights flash four times, the buzzer bi four times, and the control output interface outputs an action signal after 8 seconds.
4. When the gas sensor of the detector fails, the fault yellow indicator light is always on, and the buzzer bi three times every 180 seconds. At this time, you should ask a professional or send it to our factory for repair.
5. When the cumulative working time of the detector reaches the service life of the gas sensor, the yellow life indicator light flashes and the buzzer sounds three times every 180 seconds.
