Johnson Controls Refrigerant Leak Detectors

Overview

The Johnson Controls GM200-MH00 is an A2L refrigerant leak detection sensor for R32 applications that provides continuous monitoring and digital integration. It uses speed-of-sound sensing and outputs RS485 Modbus for building automation, operates from a 24 V supply, and includes a 2 ft pre-wired cable with a male connector. The sensor features continuous self-calibration, IP54 enclosure protection, and a factory-set 25% LFL alarm threshold with rapid detection response. RS485 Modbus digital output for integration with building automation systems Speed-of-sound sensing with automatic self-calibration and <7 s response (T25); factory-set 25% LFL trip point Operates on 24 V supply with 2 ft pre-wired cable and male connector; IP54 rated enclosure Product Highlights A2L R32 leak detection with speed-of-sound sensing, RS485 Modbus, 24 V power, IP54 enclosure, and <7 s response.
