After some more testing I have a correction.
As long as you use the app to lock the door the Alarm is not armed. The Alarm is only armed when you lock with the key.
If you use the Key to lock and then use the app to unlock the Alarm will sound.
If you use the app to lock then use the app to unlock the Alarm is not active so will not sound when you open the door.
