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).
