The AXD-IR+ is in a UniMount wall panel that fits into most US-style single-gang enclosures. The AXD-IR+ works with AMX 38 kHz or 455 kHz IR transmitters. Note: The AXR-IRSM+ swivel-mount version is also available for wall or ceiling installations: FIG. 1 AXD-IR+ UniMount IR receiver AXD-IR+ Specifications Dimensions (HWD): 4.68" x 2.93" x 1.44" (118.87 mm x 74.42 mm x 36.58 mm) Available Colors: White (FG456-10) and Black (FG456-11) Receive Frequencies: 38 / 455 kHz (user-selectable) Mounting: Mounts into most US-style single-gang enclosures. Weight: 7.8 oz. (218.4 g) Power Consumption: 35 mA Wiring and Installation Set the receive frequency, AXlink device number and IR validation level before installing the AXD-IR+. FIG. 2 illustrates the location of key components on the AXD-IR+ circuit board. IR Validation Jumper Pins 8-position AXlink Device AXlink DIP Switch Connector Receive Frequency Jumper Pins FIG. 2 Location of key components on the AXD-IR+ circuit board Setting the Receive Frequency Use the set of jumper pins on the corner of the circuit board to set the receive frequency. FIG. 3 illustrates the configuration of the jumpers.. Note: The unit will not operate with one set of pins configured for 38 kHz and the other set of pins configured for 455 kHz. • To receive 455 kHz (default setting), position both jumpers on pins 1 and 2 (away from the edge of the circuit boards). • To receive 38 kHz, position both jumpers on pins 2 and 3 (near the edge of the circuit boards). Setting the AXlink Device Number 1. Locate the 8-position Device DIP switch (FIG. 2). 2. Set the DIP switch according to the DIP switch values shown below. Switch 12345 6 7 8 Value 1 2 4 8163264128 The device number is set by the total value of DIP switch positions that are ON (down). The Axcess software program in your system typically uses device numbers 128 through 255 for the panels. As an example, the DIP switch in FIG. 4 defines device number 129 (1+128=129). FIG. 4 Example Device DIP Switch set to 129 Note: If you later change the device number, remove and reconnect the AXlink connector to enter the new device number into memory. Sensor IR Validation Level The IR validation level is set on the receiving device (such as an AXC-RCVI). Setting the IR Validation Level An IR transmitter must send repetitions of data for the receiver to accept it as valid data. In some installations, a light wall color or other physical condition may interfere with the sensor's or receiver's ability to sense the transmitted signal. The signal may reflect or bounce and become distorted. The receivers can be set to use either two or three repetitions of sequential signals to validate and accept the signal data. Perform the following steps to set the receiver's IR level. 1. Locate the IR jumper pins (J1) (FIG. 5) on the circuit board (FIG. 2). 23 23 J1 J1 Setting for 2 validations Setting for 3 validations FIG. 5 IR validation jumper pin settings 2. Position the IR validation jumper (FIG. 5) to select the number of valid IR data repetitions to be accepted: • Position the jumper at 2 to have the unit validate 2 sequential signals. • Position the jumper at 3 to have the unit validate 3 sequential signals. Wiring the IR Sensors and Receivers The AXD-IR+ uses a 4-pin AXlink connector for power and data. If the distance between the receiver and Central Controller exceeds power consumption limits, you can connect a local 12 VDC power supply to the AXlink connector. Setting for 38 kHz Setting for 455 kHz FIG. 3 Receive frequency jumper settings IR SNSR 38/455 kHz IR SNSR 38/455 kHz Preparing Captive Wires You will need a wire stripper and a flat-blade screwdriver to prepare the captive wires: 1. Strip 0.25 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 in this section. 3. Turn the flat-head screws clockwise to secure the wire in the connector. Note: Do not over-torque the screw. Doing so can bend the seating pin. Wiring Guidelines The AXD-IR+ 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 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 the receiver 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 @ 35 mA Maximum Wiring Length Wire Size Distance 18 AWG 3000 feet (914.40 m) 20 AWG 2121.64 feet (646.68 m) 22 AWG 1,322.75 feet (403.17 m) 24 AWG 833.80 feet (254.14 m) If you install the unit farther from the Central Controller than recommended in this table, connect an external 12 VDC power supply, as shown in the following wiring diagrams.
