unit’s current draw.

Control

In some cases, the total current drawn may result in a value not shown in the

chart. For example, if you intend to use #22 gauge wire and the total current

drawn is 400 mA (a value midway between 300 mA and 500 mA), the

maximum wire length you should use is approximately 65 ft (a length midway

between 50 and 80 feet). Other maximum wire lengths for values of current not

shown in the chart can be calculated in a similar manner.

Maximum wire lengths for a device that is homerun to the control can also be

determined from the chart, based on the current draw of that device alone.

MAXIMUM WIRE LENGTH

* Includes Remote

Consoles, RF Receivers, and Zone Expander.

Note: The length of all wire runs combined must not exceed 1500 feet 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.
