MGS-401 Entrance Monitor

The MSA Bacharach® MGS-401 Entrance Monitor centralizes the status of up to four (4) MSA Bacharach diffusion Gas Detectors, which in turn provides an audible and visual alarm outside a monitored space. In addition, the MGS-401 displays any gas concentration level in the space for additional information and visual monitoring. System configuration will determine whether the alarm signals are addressed in the monitored space or at a controller or BMS/BAS level.

 

Combining the MGS-401 Entrance Monitor with the MSA Bacharach MGS-408 Gas Controller and diffusion Gas Detectors provides a complete, single source gas detection system with an easy means of achieving compliance with refrigeration safety standards such as IIAR, ASHRAE 15, CSA B52 and EN376.

  • Perimeter strobe for “at-a-glance” system / alarm status
  • Seamless integration with all MSA Bacharach diffusion Gas Detectors
  • MGS-408 Controller powers up to (8) total of combination of MGS-401(s) and MGS Diffusion Gas Detectors
  • Modbus RTU Master / Slave provides seamless integration from connected gas detectors to many third-party BMS / BAS
  • Audible and visual alarms enable compliance with IIAR, ASHRAE 15, CSA B52 and EN378 – no additional hardware required
