Abstract
The invention relates to an access control device, in particular for a switchgear cabinet system, having a central unit, which is designed to receive and evaluate access authorization data stored on personal transponders and to output release signals via a wireless signal transmission link and to release a relevant interlocking unit, and which has an authentication device with a testing stage in which comparison data for testing the received access authorization data for access authorization is present. Increased security is achieved in that, in addition, at least one input station having an input unit is present, which is or can be used to establish a wireless data transmission connection to the central unit for the transmission of input data that is different from the access authorization data, the authentication device is designed to operate in two stages and has a further testing stage, which is designed for the direct or indirect allocation of the input data to the access authorization data and to check agreement between the access authorization data and the input data with regard to the access authorization, and the central unit is designed to output the release signals when the access authorization has been established after checking by means of the further testing stage.
