Chapter 3: Installation & Startup
Overview
This chapter describes procedures to mount the M2A Transmitter in the monitoring environment
and wire it to input power and devices.
Mounting the M2A Transmitter
1. Select a mounting site that is representative of the monitoring environment. Consider the
following when you select the mounting site.
• Select a site where the junction box is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration procedures. The
site should be easily accessible.
• Select a site where the target gas is likely to be found first. For lighter gases, mount the
detector near the ceiling; for heavier gases, mount the detector near the floor.
2. Use #10
screws through the M2A junction box’s two mounting slots to secure the junction
box to a vertical surface. Figure 6 shows the outline and mounting dimensions. Mount the
M2A with the detector facing down as shown in Figure 6.
