MGS-402 | MGS-408 : leak detection controllers

The Bacharach MGS-402 and MGS-408 controllers can be used to connect the MGS-400 series and MGS-550 series of sensors to form leak detection units for refrigerants, toxic and combustible gases.

The installation of a leak detection system not only ensures compliance with regulations, it also ensures the safety of people (operators, managers, employees), respects the environment and can help achieve financial savings.

The MGS-402 controller allows the connection of up to 2 MGS-410 detectors to form a 2-probe, 2-level detection unit.


The MGS-408 controller allows the connection of up to 8 detectors: MGS-410, MGS-450, MGS-460, or MGS-550 detectors to form a central detection unit with 8 probes and 2 detection levels.

This equipment can be connected to a centralised building management system.


They meet the recommendations of both EN 378 and ASHRAE 15 safety standards for leak detection.
