Bacharach’s MGS-408 Gas Detection Controller centralizes the status of up to 8 gas detection channels in a single location.
The digital display provides a real-time view of the gas concentration and status at each gas detection point. It also allows for the controller to be configured in minutes via the intuitive menu system.
A bank of LEDs corresponds to each connected gas detector; showing power, alarm status and fault indicators.
The MGS-408 can provide power for up to 8 gas detectors, which can be daisy-chained along with Modbus communication to each gas detector; simplifying and reducing the cost of installation.
Integration is possible with Bacharach’s MGS-400 Series, MGS-250 andMGS-550 Gas Detector platforms; allowing for a gas detection system design which can utilize the benefits of multiple gas detector types as required in different locations (machinery rooms, cold storage rooms, walk-in freezers and food preparation areas).
Combining the MGS-408 with Bacharach’s range of gas detectors provides a single system with an easy means of achieving compliance with refrigeration safety standards such as EN 378 and ASHRAE 15.
LED Status Indication - At-a-glance visualization of whole gas detection system alarm status
Integrates with Gas Detectors - Integrates the MGS-250,MGS-410, MGS-450, MGS-460 and MGS-550; creating a system suitable for applications with different requirements at multiple monitoring points
Power Gas Detectors - Saves time and money on electrical installation
Modbus RTU Master to Gas Detectors - Gathers full set of gas detector status
Modbus RTU Slave to BMS / BAS - Integrates into BMS / BAS or refrigeration controllers
Event logging via SD - Card Retains / exports alarm and status history of the gas detection system
Display Screen - Displays real time data from all gas detectors in the system and offers simple configuration of controller
Audible and Visual Alarms - Complies with ASHRAE 15 / EN 378 - no additional hardware
