Chapter 2: Description
Overview
This chapter describes the components of the M2 transmitter. The transmitter is a 4 - 20
mA type detector head. It consists of the combustible gas detector, calibration adapter/
splash guard, terminal PCB, the M2 junction box, and the detector junction box. The two
junction box configuration is intended for situations where the detector needs to be
installed at an inaccessible location. The detector junction box can be installed at the
inaccessible location and the M2 junction box can be installed in a more readily accessible
area.
