Johnson Controls Refrigeration Sensor for Refrigerant

The Johnson Controls Refrigeration Sensor for Refrigerant is an A2L refrigerant leak detection sensor from the GM200 series. It is used in refrigeration and HVAC systems that run on mildly flammable A2L refrigerants. Each variant in the line is set up for a specific A2L refrigerant. Choose the variant that matches the refrigerant in your system.

Key Features:

• A2L refrigerant leak detection: Detects refrigerant leaks as part of a refrigerant leak detection system (RLDS) that can start a mitigation scheme.
• RS485 Modbus output: Communicates with the controller over RS485 Modbus.
• 24 V operation: Runs on a 24 V power supply.
• Fast warm-up: Warm-up time is under 5 seconds.
• Environmental compensation: Monitors temperature and humidity and uses them to recalibrate itself, so performance stays consistent without operator intervention.
• Fault detection: Can detect several types of faults.
• Wide operating range: Rated for ambient temperatures from -40°F to 221°F (-40°C to 105°C) and 5% to 95% RH, noncondensing.
• Controller compatibility: GM200 series A2L sensors are the only A2L sensors compatible with the System 550 C550CCN control module.

Installation Notes: Mount the sensor with #10 sheet metal screws, tightened to a maximum of 30 in.·lb. Place it where the inlet will not be blocked, where the white filter membrane will not collect dust or dirt, and where water cannot collect on the sensor cover. Water, debris, dust and insects can impair the sensor's ability to detect refrigerant.

This sensor line suits technicians and facility managers who need A2L-compliant leak detection for refrigeration equipment.
