Abstract (en)

[origin: EP0543176A1] The invention relates to an intrusion alarm system with a central intrusion alarm station and an operating unit which can be connected to the central intrusion alarm station. Such operating units must be designed to be very rugged for protection against sabotage attacks and environmental influences, and thus be very costly. The invention is based on the object of creating an intrusion alarm system which has a simple equipment structure and provides safety against sabotage attacks and atmospheric influences. This object is achieved by the fact that the operating unit is mobile and is only temporarily connected to the central intrusion alarm station and that the connection between operating unit and central station is formed by a contactless transmitting/receiving device or by a galvanic contact interface. <IMAGE>
