Model 117A4 Carrier Installation Instructions Installing Multiple Carriers

Installation Self Test with a Single Radio Module in Each Carrier

1Wait a few seconds after powering the carriers, then verify that the carriers’ OUT OF SYNC LEDs are not lit.

2The following illustration shows the correct LED lights for a five-carrier installation with one radio module installed in each carrier. This example installation has four 117A4 carriers—one acting as the control carrier and the other three acting as expansion carriers—and one 117A3 carrier acting as an expansion carrier.

When the correct installation procedures are followed and one radio module is present in each carrier, the red OUT OF SYNC LEDs will not be lit on any carrier, no matter which model. The other LEDs will be lit as follows:

~Model 117A4 control carrier CONTROL/EXPANSION LED = Green

~Three Model 117A4 expansion carriers CONTROL/EXPANSION LED = Amber

~The radio modules’ PASS and POWER LEDs = Green

The Model 117A3 expansion carrier has no CONTROL/EXPANSION LED, but the DIP switch in Slot 4 of the carrier is set to Expansion.
