When the user presents a credential, the door opens but the related area does not disarm even though the user's authority level has a D in Disarm Level.
The User Group pertaining to the user of the credential may be disabled.
If a user's authority level has M selected in Security Level and the user presents their credential to a door entering a Master Armed area, the door will open regardless of the enabled state of the user's User Group. If this user's User Group is not enabled at the time when the card is presented, the related area will not disarm regardless of the selection made in Disarm Level in the users authority level. Further, the user's passcode will not work during the time when the User Group is not enabled leaving no means of disarming the area.
