MSA Safety, Inc. (NYSE: MSA) the global leader in the development, manufacture, and supply of sophisticated safety solutions that help to protect people and facility infrastructures, today announces the launch of the MSA Bacharach® MGS-401 Entrance Monitor. The MGS-401 improves facility safety by displaying gas concentration levels outside the monitored area. This entrance monitor provides clear audible and visual alarms with a perimeter strobe, enabling compliance with IIAR, ASHRAE 15, CSA B52, and EN378, whilst alerting personnel of potential risks before entering the space.

Beyond alarm level alerting, the MGS-401 Entrance Monitor displays active gas concentration levels of up to four diffusion gas detectors for centralized monitoring. The MGS-401 has been designed specifically for safety compliance in refrigeration applications and is ideal for machinery rooms, walk-in freezers, cold rooms, industrial cold storage, and chiller rooms.

Ken Easterday, Product Line Manager for MSA Bacharach, explains, “By combining the MGS-401 Entrance Monitor with the MGS-408 Gas Controller and diffusion Gas Detectors, a complete, single-source gas detection system can be obtained. This in turn provides an easy means of achieving compliance with refrigeration safety standards”. Ken continues, “Modbus RTU functionality provides seamless integration from connected gas detectors to many third-party BMS / BAS and so alarm signals can be addressed both in the monitored space or at a controller of an integrated building system”.

To pre-order your MGS-401 Entrance Monitor, contact your nearest MSA Bacharach distributor. Visit myBacharach.com/mgs-401 for more information or to request a live demonstration.
