MSA MVR-300 VRF Refrigerant Gas Detector

The MVR-300™ VRF Refrigerant Gas 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) systems. 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.

• Fits in standard 3-gang electrical boxes for easy installation (not suitable for electrical junction boxes)
• Low profile / flush mount for aesthetically non-intrusive appearance
• Two relays and Modbus Communications for notifying building management & initiate counter measures
• Alarm options (LED, buzzer, two levels, configurable delay and fail-safe) to alert occupants and remotely inform building management of alarm location for rapid response as required
• Refrigerant specific sensors for enhanced safety
• Self diagnostics and simple field calibration for easy maintenance
• Unique plug-in field replaceable pre-calibrated sensor for low cost of ownership
