* Includes Keypads, RF Receivers, Zone Expander/Relay Units, or 4285/4286 Phone Module.
Maximum wire lengths for any device that is homerun to the control can also be determined from the Wiring Run
Chart, based on the current draw of that device alone.
The length of all wire runs combined must not exceed 1500 feet (457m) when unshielded quad conductor cable is
used (750 feet if shielded cable is used). This restriction is due to the capacitive effect on the data lines when
quad cable is used.
