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.
•
For the M2A 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.
•
Mount the detector junction box near the floor, where CO

is likely to be found first.2
•
The junction boxes should be mounted no further than 200 feet from each other.
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 for the M2A junction box. Figure 7 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 7.
