Thanks for the response and helpful info!
With I3/I4 in analog mode and otherwise factory defaults (0 for both alarm trip points), I did a query on AN1 to peek the analog value of the input that has a dry contact attached to it with the pullup resister in place. The analog value queries as 1023. Based on what you said about GND being Off in analog mode, would this suggest that my contact is currently open?
