Abstract

The invention relates to an alarm glass assembly, comprising a glass pane (1), a resistance sensor (2) and an evaluation unit (3), wherein the resistance sensor is disposed on the glass pane (1) and has a sensor resistance change in the event of a change in the physical state of the glass pane (1), and wherein the evaluation unit (3) is electrically conductively connected to the resistance sensor (2) and is designed to capture a first sensor resistance value (R1) at a first time (t1), to capture a second sensor resistance value (R2) at a second time (t2), to compare the first and the second sensor resistance value (R1, R2) and to determine a sensor resistance difference (ΔR) and to determine a time difference (Δt) between the first and the second time (t1, t2) and to determine a gradient from the sensor resistance difference (ΔR) and the time difference (Δt) and to output a signal (4) if the gradient exceeds a threshold value which can be stored. The invention also relates to a method for detecting glass pane damage.
