Basic Function
When the flammable gas density reaches to response setting value of density in its surrounding environment, the alarm can give out alarm signal of sound, light and networking. In the alarm state, the ambient concentration of combustible gas down to the rated value, the alarm can be automatically restored to normal monitoring state. It has red, yellow, green three state indicator lights and one built-in buzzer, show the following three kinds of states separately:
1. Green indicator lights up, the power supply operates normally, and in the state of monitoring;
2. Yellow indicator lights up with the sound of the buzzer, alarm faults(mainly on sensor);
3. Red indicator lights up, with the buzzer noise and networking output, indicate the alarm is in alarm state.
Green indicator turn off, yellow indicator flash one time every 30 seconds, means 220VAC power off and using 9V backup battery(when battery voltage lower than 8.2V it will alarm, yellow indicator flash and buzzer sound)
