5. Quick Start Guide Honeywell MDA Scientific Midas Toxic Flammable And Oxygen Gas Detector 1 Introduction The Honeywell Analytics MIDAS gas detector is an extractive gas sampling system that draws a sample locally or from a remote point to a sensor cartridge that is located inside the detector s chassis A wide range of toxic flammable and oxygen gas sensor cartridges are available that enable detection of gases used or generated in the Semiconductor manufacturing industry and other manufacturing industries The MIDAS gas detector comprises of 4 main parts the main chassis the mounting bracket assembly the sensor cartridge and the unit cover Diagram 1 details the MIDAS general arrangement Additionally there is an optional Pyrolyzer module required for the detection of NF and an optional Analog module for the connection of external 4 20 mA devices This Quick Start Guide provides basic installation set up and operation information for the main detector unit For more detailed information on other features and options please refer to the operating manual part number MIDAS A 001 Diagram 1 MIDAS general arrangement exploded view Unit cover Main chassis Mounting bracket assembly Sensor cartridge IB MDAs Quick Start Guide MIDAS A 020 Issue 2 2 Mounting Details The MIDAS gas detector has an integral mounting bracket assembly that is easily mounted to a suitable vertical surface such as a wal
