6. Connect the wires to the terminals using the terminal block.
CAUTION: If using shielded cable, leave the shield drain wire insulated and disconnected at the
detector. You will connect the opposite end of the cable’s drain wire at the controller.
7. Secure the junction box cover to the junction box.
8. Route the cable or wires in conduit leading from the detector through one of the
conduit hubs at the controller. Use appropriate conduit fittings and construction
technique for the environmental rating of the controller. RKI controllers are typically
rated NEMA 4X.
CAUTION: Do not route power and detector wiring through the same conduit hub. The power
cable may disrupt the transmission of the detector signal to the controller.
9. Connect the wires to the appropriate controller detector terminal strip. See the
controller operator’s manual and the controller’s detector head specification sheet for
the 65-2502RK detector.

10. If using shielded cable, connect the cable’s drain wire to an available chassis ground at
the controller. RKI controllers typically have a ground stud that is a convenient
grounding location.
