AXB-REL8 Axcess Relay Controller

Connection and Wiring

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.

The device can be 1 of the 255 devices in an Axcess, AXCENT, AXCENT2, or AXCENT3system.

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.

As an example, the following DIP switch (FIG. 2) defines the AXB-REL8 as device number

97 (1 + 32 + 64 = 97).

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.

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.

Connection and Wiring

4AXB-REL8 Axcess Relay Controller

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.

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.

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.

Wiring Guidelines at 170 mA

Wire Size Maximum Wiring Length

18 AWG 690.42 feet (210.43 m)

20 AWG 436.80 feet (133.13 m)

22 AWG 272.33 feet (83.00 m)

24 AWG 171.66 feet (52.32 m)

If using power from AXlink, disconnect the wiring from the control system before

wiring the AXB-REL8.

Connection and Wiring

AXB-REL8 Axcess Relay Controller

AXlink data and power connections

Connect the control system's AXlink connector to the AXlink connector on the rear panel of the

AXB-REL8 for data and 12 VDC power as shown in FIG. 3.

Wiring AXlink with optional 12 VDC power supply

Connect the control system's AXlink connector to the AXlink connector on the rear panel of the

AXB-REL8 as shown in FIG. 4.

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.
