Table 2: Polling Loop Wiring Using Shielded (or metal conduit) one side of the shield to ground.

Wiring Notes and Recomendations

• Twisted, stranded, non-shielded cable is recommended. Avoid sharp bends in the wire.

• Shielded cable, running Aux power in the same jacket, and/or running wire in metallic conduit increase the

capacitance of the wire run, which limits distances.

• Observe device and control requirements on serial number vs. dip-switch mode.

• Avoid running the cable near keypad wiring, intercom, or AC power lines, anything emitting RF noise.

• If the V/Plex device will go serial the device has to be programmed as serial.

• Shielded wire should have one end of the shield to good Earth Ground.
