When wireless points are faulted, they display as 'Short' to the panel. When the wireless point tamper switch is faulted it will display as an 'Open' to the panel.
The panel when using a D8125INV and wireless points shows normal/faulted when point transitions from normal to off normal but the control always shows shorted.
Problem may be caused by another point expander connected to the control panel. Remove D8125INV from control panel and determine if points go missing. If points remain active (normal, faulted, etc) the control panel is interfacing with the points through another addressable point expander.
