Door Groups

• You'll find there is a default door group called All Doors. This is created by the system and cannot be deleted or changed.
• Whenever a new door is created, it is added to the All Doors door group automatically.

  Because of this, use of the All Doors door group should be used with caution.
  An example of where this would be a problem would be at a research institute dealing with dangerous substances. If a new door was created in the system that controls access to a biohazard area, anyone with the All Doors door group would automatically have access to this door.
