Gas leak detection and monitoring instrument manufacturer Bacharach has released a new dual-channel gas detection controller, the MGS-402.

Designed for refrigerant, toxic and combustible gas detection applications, the new 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).

Powered by 110-240V AC, the MGS-402 provides three 10A output relays to initiate auxiliary ventilation or restrict refrigerant flow, two analogue outputs for interface to a BMS or fire/safety panel packaged in a 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.

Remote silence input enables silencing the alarm from outside the monitored environment. Configuration of the system is simple and intuitive, reducing installation time.
