Use the passive glass breakage detector to monitor individual window panes. The detector is fixed to the window
pane to be protected. The ultrasound signals resulting from glass breakage are detected and reported to the
alarm center. The passive glass breakage detector is fixed between 20 and 50 mm from the window frame.
Important: The detector should be fixed in such a way that you notice immediately if there is no contact to the
pane. The cable should not be in danger of being damaged when the window is opened and closed. If fixed in a
corner of the window, the passive glass breakage detector monitors an area of up to 4m². Its maximum
monitoring radius is 2 meters. The passive glass breakage detector works with an integrated piezo element. It
reacts to the sound frequency caused by breaking glass. In the event of an alarm, a CMOS relay is opened. The
passive glass breakage detector is potential-free, i.e. no voltage supply is required. This makes the detector ideal
for wireless systems. The passive glass breakage detector is available in white (FU7300W) and brown (FU7300B).
