Junction Box
The junction box allows you to install the detector at a mounting site that is remote from a
controller, and it protects the detector wiring connections. Two conduit hubs allow you to
mount the detector to the junction box and connect the wiring from the detector to a
controller. Three spacers installed on the back of the junction box control the distance of
the junction box from a mounting surface and insure that there is enough room to install a
calibration cup on the detector during calibration. The terminal block within the junction
box facilitates the wiring process. A cover on the front of the junction box allows access to
the interior of the junction box.
Installation
This section describes procedures to mount the CO detector in the monitoring
environment and wire the detector to a controller.
Mounting the CO Detector
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 detector 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 detector
at approximately breathing level.
