About this app

The Bacharach MGS-400 App allows users to configure, maintain and interface with compatible MGS-400 gas detectors. Once a Bluetooth connection has been established, the app replaces the need for specialty training / tools and makes compliance with safety standards (ASHRAE 15, EN 378) easy and effective.
Features include:

- Configuration (Rename device, define alarm thresholds, adjust Modbus settings, configure relay behavior and manage analog output settings.)
- Maintenance (Test LED / buzzer function, relays and analog output level.)
- Calibration (View sensor type, serial number and “Calibration Due” timer and initiate zero / span calibrations with customizable field calibration certificate.)
- Intuitive Interface (View current gas measurement and acknowledge alarm / fault status.)

this app doesn't find their products. avoid both the app and products. also for those wondering the sensors are useless unless you can connect to the app. stick with reliable companies for sensors folks.

We're sorry to hear that you're experiencing issues. Please be sure that you are connecting to a compatible gas detector (MGS-410/450/460) and that it has been placed into discovery mode (tap mag switch #1). If you're still unable to connect, you may setup the instrument manually with the mag switches. Email help@mybacharach.com for more help.
