AX22 2-Door Expander

The AX22 two-door expansion module will hold its configuration and continue operating even if communication with the controller is lost. Add up to four AX22 two-door expanders per ATRIUM controllers for a maximum of 10 doors per controller.

The effortless auto-detect technology identifies the AX22 on the RS485 communication bus and synchronizes it with the AC22 or A22 controller. A pre-assembled universal power supply is included with every AX22, making this unit an industry leader in efficiency and simplicity.
