the receiver or sensor and the Central Controller. The maximum wiring lengths are based on a minimum of 13.5 volts available at the Central Controller's power supply.

Wiring Specifications

Maximum Wiring Length

Wire Size	IR Sensors	IR Receivers
18 AWG	4,696 feet (1431.34 m)	3,354 feet (1022.30 m)
20 AWG	2,970 feet (905.26 m)	2,121 feet (646.48 m)
22 AWG	1,851 feet (564.18 m)	1,314 feet (400.511 m)
24 AWG	1,167 feet (355.70 m)	833 feet (253.90 m)

If you install the IR sensor or receiver farther away from the Central Controller than recommended in the Wiring Specifications table, connect an external 12 VDC power supply, as shown in the wiring diagrams in this section.

Connecting the Wiring

The following paragraphs describe wiring connections using AXlink for data and power, using AXlink plus an external 12 VDC power supply, and wiring the IRX-DM+ or IRX-SM+ to the AMX IR receiver.

Wiring the AXD-IR+ or the AXR-IRSM+ to AXlink

Install the AXlink data/power bus wiring as shown in FIG. 15.
