I don't believe the system's Centralite Keypad driver supports the XHK1-UE keypad, although it may work the battery levels will be way off, it reports 6V vs 3V. The XHK1-UE is supported by the Centralitex driver using Nyckelharpa.
Using the keypad for a motion detector is problematic since it only responds within a few inches from the device, and is mainly used by the device hardware to light the keypad. However, the Centralitex driver creates a motion event for all supported keypads and motion shows in the device's "Current States" including the Iris V3.
