Bacharach MVR-300 [6203-0042] Refrigerant R-32 Detector, Range: 5,000 ppm; Low Alarm: 1,000 ppm; High Alarm: 2,000 ppm. The MVR-300™ detector is specifically designed to provide continuous monitoring for refrigerants associated with high-efficiency, high volume refrigerant cooling and heating systems, such as VRF/VRV (Variable Refrigerant Flow/Variable Refrigerant Volume) sytems. Typical applications include hotels, dormitories, hospitals, office buildings, and apartment buildings.

The MVR-300™ audible and visual alarms alert occupants and simultaneously communicate to Building Management Systems/Building Automation Systems (BMS/BAS). Two on-board relays can be used to close valves, activate alarm devices and exhaust fans or initiate emergency calls to rescue teams.

The on-board Modbus RTU interface provides real-time information about concentrations, status and settings. It also enables custom configuration of the MVR-300™ to any application specific requirements using multiple Modbus registers.

The MVR-300™ is designed for easy installation and simple maintenance.

IMPORTANT NOTE:   Large refrigerant leaks into occupied spaces can reach concentrations that pose a suffocation risk to the occupants. The MVR-300™ is not designed to be used as the sole safety device for this risk. Safety of the occupants also must take a system designed approach that includes things such as ventilation, detection, early warning, mitigation and design redundancy.
