 Description
Bacharach’s advanced MGS-550 gas detector can utilize any combination of sensor technologies, including 
electrochemical, semiconductor (MOS), catalytic bead or infrared, in a single platform for unparalleled detection
capability. It meets ASHRAE 15 and EN 378 requirements. The MGS-550 can easily be connected to any central
control system using the current and volt analog output or the Modbus RTU interface. With three user assignable
relays, it can also function as a stand-alone unit without the need to wire alarm devices back to a central system.
The straightforward menu structure is identical throughout the platform reducing the amount of training required 
for installing and maintaining this product family. At any point in time, the instrument can be upgraded from a
one sensor to a two sensor system by simply registering another sensor. The MGS-550 is furnished with two analog
outputs which can be assigned as redundant for one or for transmit the signal of two sensors.
