Abstract

Der die bei einem Glasbruch auftretenden typischen Schwingungen erkennende Empfänger innerhalb des Glas­ bruchmelders besteht aus einem mikromechanisch her­ gestellten Frequenzsensor (F), der zusammen mit einer elektronischen Auswerteeinrichtung (A) und einer Sen­ deeinrichtung (SE) in ein gemeinsames Substrat (S) hinein integriert ist. Die Sendeeinrichtung (SE) gibt eine erkannte Glasbruchmeldung drahtlos an eine Empfangseinrichtung weiter, welche Zugang zu einer Alarmanlage hat. Der Glasbruchmelder enthält außer­ dem eine eigene Stromversorgung (SV). The typical one that occurs when a glass breaks Vibration-detecting receivers inside the glass break detector consists of a micromechanical put frequency sensor (F), which together with a electronic evaluation device (A) and a Sen device (SE) in a common substrate (S) is integrated into it. The sending device (SE) gives a detected glass breakage message to one wirelessly Receiving device further, which access to a Has alarm system. The glass break detector contains except which has its own power supply (SV).
