Description:
The PS-372 is an electronic device using advanced digital technology. It employs an 8 bit microprocessor to perform constant analysis of the glass environment it is protecting. The PS-372 hears the unique multi frequency acoustic shock wave of glass-breaking; then it analyses the signal digitally by a microprocessor and decides whether it is the sounds of an actual glass break event or not. The micro algorithm identifies multiple variations of the glass break signal data in both unique time and frequency domains. In short; it compares the sound it hears with the wave shape of actual breaking glass in the memory database and ignores extraneous noises. Since the detector analyses wave shape but not amplitude, it will detect through curtains, drapes, blinds and sun tinting applications. Thus PS-372 is not crippled by post installation changes such as curtains or laminated window application.
