Setting the DEVICE Dip Switch  
The eight-position Device DIP switch is located on the front panel of the AXB-REL8 as shown in  
FIG. 1 on page 1. Each device in the AXlink bus must have a unique AXlink device number.  
If you later change the device number, remove and reconnect the AXlink connector.  
This enters the new device number into memory. The device number takes effect only  
on power-up.

The device can be 1 of the 255 devices in an Axcess, AXCENT, AXCENT , or AXCENT system.  
The device number must match the device assignment in the Axcess program. AMX assigns device  
numbers into the following three segments:  
Cards 1 through 95  
Boxes 96 through 127  
Panels 128 through 255  
Set the device number by setting the DEVICE DIP switch. The device number is the total of all of  
the switches in the ON (down) position. The following table shows the switch numbers and their  
corresponding values.

Set the AXB-REL8 device number before connecting AXlink wiring. Do not install relay wiring at  
this time.  
Wiring Requirements  
The AXB-REL8 uses a four-pin AXlink Central Controller connector for power and data. If the  
distance between the AXB-REL8 and the Central Controller exceeds power consumption limits,  
you must connect an optional 12 VDC power supply. Refer to the following section for more  
information.

Connection and Wiring  
Do not connect power to the AXB-REL8 until the wiring is complete. If you are using a  
12 VDC power supply, apply power to the AXB-REL8 only after installation is  
complete.  
Preparing captive wires  
To connect the wiring into a captive-wire connector:  
1. Strip 1/4 inch off the wire insulation for all four wires.  
2. Tin 2/3 of the exposed wire.  
3. Insert each wire into the appropriate captive-wire connector up to the insulation.  
4. Tighten the captive screws to secure the fit in the connector.  
Wiring guidelines  
The AXB-REL8 requires 12 VDC power to operate properly. The Central Controller supplies  
power via the AXlink cable. The maximum AXlink wiring distance between the Central Controller  
and AXB-REL8 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  
AXB-REL8 and the Central Controller, based on the maximum power consumption rating of 170  
mA (all eight relays ON).  
The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts  
available at the Central Controller's power supply.  
Wiring Guidelines at 170 mA

436.80 feet (133.13 m)  
272.33 feet (83.00 m)  
171.66 feet (52.32 m)  
If the AXB-REL8 is installed farther away from the control system than recommended in the above  
table, connect a 12 VDC power supply to the AXlink connector on the AXB-REL8 rear panel (see  
Wiring AXlink with Optional 12 VDC Power Supply).  
Connecting the Wiring  
The following paragraphs describe wiring connections for using the AXlink and relay connectors.  
If using power from AXlink, disconnect the wiring from the control system before  
wiring the AXB-REL8.

FIG. 4 Wiring AXlink with Optional 12 VDC power supply  
Central Controller  
Use a 12 VDC power supply when the distance between the control system and AXB-REL8  
exceeds the limits described in the Wiring Guidelines at 170 mA table on page 4, or the power  
supply current capacity cannot accommodate the 170 ma (max) draw of the AXB-REL8. Make sure  
to connect the GND and +12 VDC wire on the AXB-REL8 AXlink connector end. Do not connect  
the optional +12 VDC power supply wire to the control system's power supply side of the AXlink  
connector (FIG. 4).  
Checking the installation  
After set-up is complete:  
1. Check continuity of relay wiring.  
2. Check cable numbers and wiring, interfaces and sources against supplied documentation.  
3. Install tab strips to jumper between shared commons and clip off excess tabs.  
4. Insert relay wiring terminals into AXB-REL8.  
Relay connections  
The relay specification is 1 A @ VAC or VDC. FIG. 5 on page 6 shows the relay wiring diagram  
for the AXB-REL8. The dotted lines are used to indicate commons. Install supplied tab strips to  
jumper between shared commons. Clip off excess tabs and bend strip up, away from other wiring.

Testing the installation  
1. Check AXlink status LED - it should blink once per second (see Specifications table for  
AXlink status LED).  
2. Relay LED lights, but source does not activate:  
3. Check wiring continuity.  
4. Check jumpers used for shared commons.  
5. Check cable and source against supplied documentation.  
6. Check operational status of interface or source.  
Rack-Mounting the AXB-REL8 (optional)  
To rack-mount the AXB-REL8 into the optional AC-RK Accessory Rack Kit:  
1. Remove any connected relay and AXlink connectors from the rear panel.  
2. Remove the two screws on the front panel of the AXB-REL8.  
3. Remove the front panel and the space bracket behind the panel.  
4. Place the unit in the appropriate opening in the AC-RK.  
5. Place the front panel of the AXB-REL8 on the front of the rack, over the unit.  
6. Fasten the front panel to the rack and to the unit with the two screws you removed.
