* Includes Keypads, RF Receivers, Zone Expander/Relay Units, or TeleCommand Phone Module.
Maximum wire lengths for any device that is wired directly to the control can also be determined from the Wiring Run
Chart, based on the current drain of that device alone.
The length of all wire runs for all partitions combined must not exceed 457m when unshielded quad conductor cable is
used (228m if shielded/screened cable is used). This restriction is due to the capacitive effect on the data lines when
quad cable is used.
