Abstract (en)
[origin: EP0474975A1] What is described is an access control device for doors which are equipped with an electrical door opener (11). To prevent an unauthorised actuation of the door opener, for example by applying a supply voltage, each door opener is activated from a central control unit (10) by means of an individual selection code. The absence of any coincidence between the transmitted selection code and a code preset in the door opener prevents the possibility of actuation. <IMAGE>
