Multiplus 24/1200 Programmable relay state

The programmable relay contacts are marked COM, NC and NO. My understanding of the relay's default behaviour and normally open is that there should be continuity between COM and NC during normal (No alarm) operation, and continuity between COM and NO if there is an alarm. I tested the continuity today, and found that there is continuity between COM and NO, and no continuity between COM and NC. This is unexpected, is my understanding of the default behaviour of the relay incorrect?

The relay's behaviour has not been changed via VE Configure, in fact I have not even downloaded it yet.

Product ID: 2667

Firmware version: 469

VenusOS Remote console shows no alarms, all show Ok under Alarm Status

Would appreciate any help.

That is the default behavior.
Important for this behavior is the "Invert virtual switch usage"

Thank you very much for the detailed and exact answer, much appreciated! I think I'll download VE Configure just to get visibility of all the settings.
