8 • 65-2481RK Multi Point Detector
Conduit Seal
The conduit seal isolates the volumes of the 2 junction boxes and preserves the explosion
proof classification of each junction box.
Junction Boxes
Use the junction boxes to install the multi-point detector at a mounting site that is remote
from the controller. The junction boxes protect the terminal strips and wiring connections
made to the terminal strips. Use the top 3/4’’ conduit hub to connect wiring from the
terminal strips to the controller. Use the cover on the front of the junction boxes to access
the interior of the junction boxes. The detectors and terminal strips are factory installed in
the junction boxes.
Installation
This section describes procedures to mount the multi-point detector in the monitoring
environment and wire the detector to a controller.
Mounting the Multi-Point 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 gases are likely to be found first.
