摘要

The device (2) has a controlling unit (15) assigned to a test body (12). The controlling unit is initiated by the performance of the test body arising in case of a damage to a signal emitting movement (16) causing a signal emission. A system component (7) is made of a homogenous material and monitored by a smaller medium stability. The system component and the test body is made of polycarbonate plastic material or nitrile butadiene rubber material.
