Wiring the IR Sensors and Receivers

The IR Sensors and Receivers use a four-pin AXlink connector for power and data. If the distance between the panel and Central Controller exceeds power consumption limits, you can connect a local 12 VDC power supply to the AXlink connector.

FIG. 14 shows the location of the AXlink connector on the rear panel of the IR sensors and receivers.

To access the AXlink connector on the AXR-IRSM+, separate the swivel-mount base from the housing. (Refer to Figure 4.) On the AXD-IR+, the AXlink connector is on the underside of the unit.

Preparing captive wires

You will need a wire stripper and a flat-blade screwdriver to prepare the captive wires.

Prepare and connect the captive wires as follows.

1.Strip .25 inch (6.35 mm) of wire insulation off all wires.

2.Insert each wire into the appropriate opening on the connector according to the wiring diagrams (following) in this section.

3.Turn the flat-head screws clockwise to secure the wire in the connector.

Do not over-torque the screw. Doing so can bend the seating pin

Wiring guidelines

The IR sensor or receiver requires 12 VDC power to operate properly. The power is supplied by the AMX system's AXlink cable. The maximum wiring distance between the Central Controller and the receiver or sensor is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The following table lists wire sizes and the maximum lengths allowable between
