Abstract

Die Erfindung betrifft ein System zur Zugangsüberwachung von Bauwerken, insbesondere Kabelkanalanlagen (3), wobei der Zugang eine Schließvorrichtung (1) aufweist. Eine hilfsenergieunabhänginge Zugangsüberwachung, die auch für Fernüberwachungszwecke geeignet ist, ist dadurch gekennzeichnet, dass mindestens ein Lichtwellenleiter (6) mit der Schließvorrichtung (1) derart mechanisch gekoppelt ist, dass die optischen Eigenschaften des Lichtwellenleiters (6) beim Betätigen der Schließvorrichtung (1) veränderbar sind.

The invention relates to a system for monitoring access to buildings, in particular cable duct systems (3), the access having a locking device (1). An auxiliary energy-independent access monitoring system, which is also suitable for remote monitoring purposes, is characterized in that at least one optical fiber (6) is mechanically coupled to the locking device (1) in such a way that the optical properties of the optical fiber (6) can be changed when the locking device (1) is actuated are.
