Bacharach’s MGS-402 Gas Detection Controller centralizes the status of up to two MGS-410 Gas Detectors, provides a complete package for your safety compliance application. On the front panel of the MGS-402 a bank of LEDs corresponds to each connected gas detector; showing power, alarm status and fault indicators. The MGS-402 can provide the power requirements for to up to two gas detectors, which can be daisy-chained with Modbus communication to each gas detector; simplifying and reducing the cost of installation.
Combining the MGS-402 Gas Detection Controller with Bacharach’s MGS-410 Gas Detector provides a complete, single source gas detection system with an easy means of achieving compliance with refrigeration safety standards such as ASHRAE 15, EN 378 and CSA-B52.
