Bacharach MGS-450 Specifications

REFRIGERANT SAFET Y COMPLIANCE

MGS-400 Gas Detectors

For Safety Compliance in Mechanical Equipment Rooms, Freezers, and Cold Rooms

DESCRIPTION

Bacharach’s MGS-400 Gas Detectors makes compliance with mechanical
equipment room and refrigeration safety codes simple and easy, saving
time and money on equipment and installation. Using the MGS-400 App,
users can intuitively use, commission and maintain their gas detection
system without the need for specialty training or tools. Pre-calibrated

Integrated

audio/visual

alarms

MGS- 410

sensor modules simplify maintenance, take minutes to exchange and do
not require the use of calibration gas. The MGS-400 sensors can trigger
additional audio-visual alarms and act as a standalone gas detection
system, or integrate easily into a BMS / BAS or with Bacharach’s optional
MGS-408 Gas Detection Controller.

FEATURES BENEFITS

Mobile App Interface Quick, easy and intuitive commissioning, conguration

and maintenance requires no special training. No tools
required to set alarm levels and behavior.

Pre-calibrated Sensors Fast and easy sensor maintenance. Eliminates need for

calibration gas.

Semi-automated Calibration Easy calibration process with mobile app. Generate

calibration certicates for documentation.

Remote Sensor Option Locate the sensor element in hard-to-reach areas

and the base unit where convenient for electrical and
communication wiring (MGS-460)
