The dormakaba registration unit 90 01 has an innovative design in an elegant, high-gloss finish and an eye-catching compact form. It blends discreetly and harmoniously into modern buildings. Together with the control unit, though separately installed, the unit secures access to buildings and rooms. Because the control device is installed in the secure indoor area the access control system is protected from sabotage. Communication between the registration unit and the control unit that goes with it is encrypted, offering a high level of security.
