monitoring site. Use the cover on the front of the junction box to access the interior of the junction
box.
Installation
This section describes procedures to mount the CO transmitter in the monitoring environment and
wire the transmitter to a controller.
Mounting the CO 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 transmitter is not likely to be bumped or disturbed. Make sure there
is sufficient room to perform start-up, maintenance, and calibration procedures.
• Select a site where the target gas is likely to be found first.
NOTE: If your application does not require a specific mounting site, mount the transmitter at
approximately breathing level.
Figure 2: Mounting the CO Transmitter
If the CO detector is mounted to the junction box, skip to step 5. If not, continue with
step 2.
2. Remove the junction box cover.
3. Guide the two wires that extend from the top of the CO detector through the bottom conduit
hub of the junction box.
4. Screw the CO detector into the bottom conduit hub of the junction box.
5. At the monitoring site, use #10 screws through the junction box’s two mounting holes to secure
the junction box to a vertical surface.
CAUTION: Mount the CO transmitter with the detector facing down (see Figure 2.)
