Abstract

The present invention relates to an alarm pane arrangement having: at least one first pane which is composed of tempered glass, having an outside surface and an inside surface, at least one transparent, electrically conductive coating which is arranged on the inside surface of the first pane, a sensor unit with a capacitive sensor which is capacitively coupled to the transparent, electrically conductive coating, where the sensor unit outputs an alarm signal in the event of deviations in a measurement signal of the capacitive sensor from a comparison value, where the capacitive sensor contains i) precisely one measuring electrode or ii) a measuring electrode and a reference ground electrode or iii) a measuring electrode, a reference ground electrode and at least one compensation electrode, and where the measuring electrode is DC-isolated from the transparent, electrically conductive coating.
