Replace an AW2 Wiegand Module

Note

• You should not need to remove any wires from any of the AW2 Module’s screw terminals, as they

can unplug.

1. Take note how the existing wiring is connected (take a picture with a smartphone) before you remove

anything.

2. Disconnect the 12V Battery if there is one present in the cabinet.

3. Unplug the mains supply plug from the power outlet.

4. If the faulty AW2 module is the outer module (i.e., not trapped between two other modules) then

jump to step 7.

5. Remove the four screws securing the outer AW2 module to the Cabinet.

6. Leaving the outer module wiring in place unplug the outer module from the faulty module.

7. Unplug (only the wired) screw terminal plugs from the faulty AW2 Module

8. Remove the four corner screws that secure the faulty AW2 to the cabinet

9. Pulling sideways, unplug the faulty module from the module that it is plugged into.

10. Plug the new module into the now vacant socket and settle the module’s mounting base so that it is

positioned over the four screw holes.

11. Replace the four screws to secure the new module to the cabinet, using an appropriately-sized flat

screwdriver.

12. Take the label that came with the new AW2 Module and fix it over the faulty module’s label on the

back page of the ACW2-XN’s Quick Install Guide.

13. Remove the necessary plugs, one at a time, from the new module (put them on the old module) and

plug the existing wired plugs into their correct positions – using your photo for reference.

14. If you didn’t have to remove an outer module, jump to step 17.

15. Plug the outer module into the side connector of the new module.

16. Secure the outer module with its four corner screws, using an appropriately-sized flat screwdriver.

17. Reconnect the AC Mains – the STAT (Status) LEDs on the Controller and Wiegand Modules will flash

rapidly for approximately one second, allow a minute for the system to boot up.

18. Using HID Access Manager, click on Device Discovery so that the new Wiegand port addresses will be

read into the system.

19. Click on “Doors”, and navigate to the door/s associated with the replaced AW2 Module. Allocate the

new Wiegand port addresses (these will be on the new label that you fixed on the last page of the

Quick Start Guide. (All other settings for the effected doors will

not

have changed.)

20. Re-connect the battery, if there is one in the cabinet.

21. The system should now function correctly.
