CD 475 offers reliable monitoring against attacks with mechanical tools. The CD 475 is a chock- and vibration sensor with 3 separate detection channels: an integration channel / saw channel for weak signals with long duration, a counting channel that senses strong impact on the monitored surface and an explosion channel which senses very strong signals from e.g. an explosion.

CD 475 shares the design with CD 470 but must be connected to analyzer IU 400 for alarm indication since it lacks built-in relay outputs. In the event of an alarm, the power consumption in the detector increases, this is detected by the analyzer IU400 which will indicate the different alarms.
CD 475 polarity independent, just like CD 470.
