The Crowcon GM Addressable Controllers provide a flexible and scalable solution for centralized gas detection monitoring across industrial facilities. Designed with a fully modular architecture, these controllers allow users to configure only the channels and functions required for their specific application—reducing both system complexity and overall cost.

Available in three models (GM16, GM64, and GM128), the system supports up to 128 input channels and delivers real-time communication, live data visualization, and advanced zoning capabilities. With multiple display modes, trend analysis, and remote web access, operators gain full visibility and control of site safety at all times. Built for reliability and ease of use, the GM series integrates seamlessly with modern gas detection networks in demanding industrial environments.
