Combustible Gas Alarm Controller Real-time Concentration Display
1. Product Overview
The M201 combustible gas detection system is an industrial-grade safety solution comprising a gas detector and alarm controller. The controller meets GB16808-2008 standards and monitors gas concentrations in ambient air, compatible with multiple gas detectors, actuators, and receivers (collectively termed "addressing units"). Detectors are deployed in hazardous indoor/outdoor leak-prone areas, while the controller operates in safe zones (e.g., control rooms).
Upon detecting gas vapors, the system displays real-time concentration levels. If levels exceed predefined thresholds, audible/visual alarms and control signals activate external safety devices to prevent accidents.
Utilizing RS485 and PowerBus architectures with ModBus RTU protocol, the M201 integrates a microprocessor and high-precision sensors for rapid, sensitive detection. Its user-friendly interface features a Chinese LCD display and keyboard for real-time data monitoring. Advanced software algorithms ensure anti-interference performance and fault diagnostics, guaranteeing stable operation.

4.Indicator Lights
| Name of the indicator light | Color | Function |
| Normal | green | When the system is operating normally, this indicator light is on. |
| Mute | red | When the fault sound and alarm sound are eliminated, this indicator light is on. |
| Total fault | yellow | When there is a fault between the controller and the detector, this indicator light is on. |
| Total alarm | red | When the detector gives an alarm, this indicator light is on. |
| Main power supply normal | green | When the main power supply of the controller is normal, this indicator light is on. |
| Main power supply fault | yellow | When there is an under-voltage of AC220V, this indicator light is on. |
| Backup power supply normal | green | When the backup power supply of the controller is normal, this indicator light is on. |
| Backup power supply fault | yellow | When there is a fault with the backup power supply (such as open circuit, under-voltage, etc.), this indicator light is on. |
| Backup power supply charging | green | When the backup power supply is charging, this indicator light is on and goes off when it is fully charged. |
| Charging fault | yellow | When there is a charging fault of the backup power supply, this indicator light is on. |
