65-2485RK-02 Multi Point Detector • 5
pins that mate with the sockets in the detector housing body. Through a series of chemical
and electrical reactions, the sensor produces an electrical output that is proportional to the
detection range of the detector.
Junction Box
Use the junction box to install the multi-point detector at a mounting site that is remote
from the controller. The junction box protects the terminal strip and wiring connections
made to the terminal strip. Use the top 3/4’’ conduit hub to connect wiring from the
terminal strip to the controller. Use the cover on the front of the junction box to access the
interior of the junction box. The detectors and terminal strip are factory installed in the
junction box.
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.
