Carrier

Control/Expansion DIP

Switch

The Model 117A3 carrier can serve as either a control or an expansion carrier. Whether you install one or more 117A3 carriers, you must set the Control/Expansion DIP switch in Slot 4 of each 117A3 carrier to indicate which role that carrier is filling.

The leftmost carrier, no matter what model number it is, must be the control carrier, and the remaining carriers are expansion carriers. The control carrier acts as the “lead” carrier—its transmit and receive patterns control the expansion carriers, ensuring that all of the linked carriers function as a single system.

It is recommended that you determine which carrier is to be the control carrier and which, if any, will be expansion carriers; then set the Control/Expansion DIP switch(es) before mounting the carrier(s) on the wall.
