How does the combustible gas monitoring device determine whether it has entered the normal monitoring state?

In industrial production, home safety, and various places involving combustible gases, combustible gas monitoring equipment has become an important tool for protecting life and property. This type of detector can sense the concentration changes of combustible gases in the air in real time, and issue an alarm in time when the dangerous threshold is reached, effectively preventing the occurrence of fire and explosion accidents. Its workflow covers multiple functional stages such as preheating, normal monitoring, self-test, alarm and fault prompt, ensuring that the equipment is always in an efficient and stable working state.When the device is connected to the AC220V power supply, the system first performs the initialization operation, all indicator lights are on and accompanied by a beep, indicating that the device enters the preheating stage. During this period, the indicator light continues to flash for about 180 seconds. The preheating process is crucial for the stable operation of the gas sensor and helps to improve the detection accuracy. If the user wants to exit the preheating state in advance, the switch can be quickly completed by double-clicking the "self-test" key, thus saving waiting time.After entering the normal monitoring state, the device will continuously detect the concentration of combustible gases in the surrounding air. Once the gas concentration reaches the set alarm threshold, the combustible gas monitor will immediately enter the alarm state, the red indicator light will start to flash quickly, and the buzzer will send out a continuous sound and light alarm signal. One second later, the control output interface will trigger an action signal, which can be used to link external devices such as exhaust fans or emergency cut-off devices to achieve automatic emergency handling. When the gas concentration falls back to a safe range, the device will automatically release the alarm state and resume normal monitoring.To ensure that the equipment functions properly, the combustible gas monitor also has a self-test function. In the normal monitoring state, short press the "self-test" button to start the self-test program. At this time, all indicator lights flash four times, the buzzer beeps four times, and the control output interface outputs an action signal after eight seconds to simulate the alarm response to verify whether the various components of the equipment are operating normally. This function facilitates daily maintenance and regular inspections, and improves the reliability of the system.When the gas sensor inside the combustible gas monitor fails, the yellow fault indicator light will be on, and the buzzer will beep three times every 180 seconds to remind the user that there is an abnormal situation. At this time, it should be repaired by professionals or sent back to the manufacturer for processing to avoid false alarms or missed alarms. In addition, the combustible gas monitoring also has a sensor life warning mechanism. When the cumulative operating time of the equipment is close to the service life of the gas sensor, the yellow life indicator will begin to flash, and the buzzer will also beep three times every 180 seconds, prompting the user to replace the sensor in time to ensure that the equipment continues to play its due protective role.The combustible gas monitoring equipment not only has a highly automated workflow, but also can help users to grasp the equipment status and environmental risks in a timely manner through a variety of signal feedback methods. Its intelligent design, precise detection capabilities, and perfect alarm and maintenance mechanisms make it an indispensable part of the modern safety protection system. Whether it is an industrial site, a commercial place or a residential house, the reasonable configuration and regular maintenance of such equipment will greatly improve the overall safety level and protect people's lives and property safety.
