This multi-channel fixed gas detector controller (available in 8, 16, 24, or 32 channels) is ideal for large-scale gas detection networks. It records up to 1,000 alarm/fault logs and stores up to 100,000 records via SD card. Each channel’s concentration value and curve are clearly shown, supporting continuous 24-hour supervision when connected to a computer—perfect for environments requiring strict gas safety control.
Multi-Channel Signal Input
- Wall-mounted design with a 7-inch high-definition color touchscreen.
- Equipped with standard RS485 input/output, supporting 8–32 channels of 4–20mA signal input.
- This gas detector controller supports connection to a computer for 24-hour real-time monitoring through PC software, with all data automatically saved to the computer.
- Each screen can display six channels of gas concentration, including concentration values, units, and real-time curves for a single channel, providing clear and intuitive monitoring.
Large Data Storage Capacity
- The fixed gas detector controller can record 1,000 sets of alarm and fault events. A standard SD card can expand storage capacity to 100,000 sets for easy historical tracking.
- Suitable for monitoring single or multiple detectors, enabling centralized management of multiple points and effectively preventing gas leakage, explosion, and poisoning hazards.
- SISCO gas detector controller supports one-key switching between Chinese and English, with additional languages available for customization to meet regional needs.
Applications
Fixed gas detector controller is used to monitor and manage signals from fixed gas detectors, providing continuous detection of hazardous gases. It is widely applied in chemical plants, pharmaceutical factories, laboratories, oil and gas facilities, warehouses, power plants, and other industrial and commercial environments.

Q1: What is a fixed gas detector controller used for?
A1: A fixed gas detector controller is used to centrally monitor and manage signals from multiple fixed gas detectors. It processes gas concentration data, triggers audible and visual alarms, and helps ensure timely response to gas leaks in industrial and commercial environments.
Q2: How many gas detectors can the controller connect to?
A2: The controller can typically connect to multiple fixed gas detectors, depending on the model and configuration. It supports single-point or multi-channel inputs, making it suitable for both small installations and large centralized gas monitoring systems.
Q3: What types of gas detectors are compatible with the controller?
Q4: The fixed gas detector controller is compatible with various gas detectors for combustible, toxic, and oxygen gases. It usually supports standard output signals such as 4–20 mA, RS485, or relay outputs for flexible system integration.
Tips: Can the fixed gas detector controller be integrated into an existing safety system?
Yes, the fixed gas detector controller can be integrated into existing safety or automation systems through standard signal outputs and communication protocols, such as 4–20 mA, RS485, or relay outputs. This allows seamless connection with building management systems (BMS), distributed control systems (DCS), and centralized control rooms for enhanced monitoring and safety management.
