Chapter 3: Installation & Startup
Overview
This chapter describes procedures to mount the M2 Transmitter in the monitoring
environment and wire it to input power and devices.
Mounting the M2 Transmitter
1.
Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
•
For the M2 junction box, 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.
•
For the detector junction box, 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.
•
The junction boxes should be mounted no further than 200 feet from each other.
2.
Use #10 screws through the M2 junction box’s two mounting slots to secure the
junction box to a vertical surface. Figure 4 shows the outline and mounting
dimensions the M2 junction box. Figure 5 shows the outline and mounting
dimensions for the detector junction box. Mount the detector junction box with the
detector facing down as shown in Figure 5.
