The door equipped with touch screen panel is maintained in a locked status as default. It can be opened by gently pressing on the dedicated key icon on the controller only if the other door is closed.
On the other hand, the opposite door is kept in the “always open status”; whenever this door is opened, the controller will not give consent to the release of the lock of the opposite door, and vice-versa.
An additional safety mechanic key lock is added to the door in the “always open” position. The logging lists of door opening is displayed on the screen and split into simple opening (no trespassing the alarm time) or critical (longer than door alarm delay).
