K3000 Plus Two-wire bus Gas Alarm Controller
The K3000 gas alarm controller is a centralized monitoring device using a two-wire bus communication method. It provides unified power supply, data acquisition, alarm management, and linkage control for multiple fixed gas detectors. Power supply and signal transmission are completed via a single two-core cable, significantly simplifying on-site wiring and improving system stability and construction efficiency.

The K3000 gas alarm controller features a clear display interface and a user-friendly human-machine interface design. It supports alarm recording, fault self-diagnosis, access control, and parameter setting functions. Suitable for building small to medium-sized to large-scale gas alarm monitoring systems, it serves as the core management unit for industrial and civil gas safety systems.
This controller can simultaneously connect to multiple bus-type gas detectors, displaying real-time gas concentration, operating status, and alarm information at each detection point. When a gas concentration exceeds the limit, the system automatically triggers an audible and visual alarm and, through relay outputs or communication interfaces, links with ventilation equipment, solenoid valves, and other safety devices, achieving a rapid and effective safety response.
