Bacharach has introduced the MGS-402 gas detection controller for refrigerant, toxic and combustible gas detection applications. The system is designed for safety compliance in mechanical rooms, cold storage facilities, walk-in freezers, and cold room applications.
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 1000ft (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.
