Bacharach launches MGS-402 dual-channel gas detection controller

The system is designed for safety compliance in mechanical rooms, cold storage facilities, walk-in freezers, and cold room applications to -40°C/-40F.

The MGS-402 is part of the MGS-400 series gas detectors that connect through Modbus to up to two remote MGS-410 gas detectors at up to 1,000ft (305m).

The MGS-402 is powered by 110-240V AC and provides three 10A output relays (fault, low alarm, high alarm) to initiate auxiliary ventilation or restrict refrigerant flow, two analog outputs for interface to a BMS or fire/safety panel packaged in an IP66 enclosure. 

Upstream Modbus connectivity enables remote configuration and communication with building management systems.

The MGS-402 has a built-in audible alarm and high-visibility visual alarm that eliminates the need for an external horn/strobe in close proximity.  The remote silence input enables silencing the alarm from outside the monitored environment.

The company said configuration of the MGS-402 is simple and intuitive, reducing installation time.
