UTC is pleased to announce that our GS930 Acoustic Glassbreak sensor is now CPNI approved
The GS930 is an acoustic glass break detector designed to detect breaking glass of framed windows around the perimeter of a building. The detector can safely and reliably detect glass breakage on both small and large objects as well as on single or multiple glazed objects.
The GS930 is an intelligent audio glass break detector using the latest microprocessor technology. The acoustic signals in the room to be monitored are recorded with a wide-band microphone. The data is then analysed 80 times a second to determine whether there has been an actual breakage of framed glass. A unique signal processing algorithm is used, so no adjustment is necessary for various types and sizes of glass.
The special 3 x 3 signal processing algorithms are based on the analysis of 3 different parameters [peak amplitude, signal duration and ambient average] in 3 different frequency ranges [low (infrasound), mid (sound) and high (ultrasonic)] that permit safe and reliable detection of glass breakage. Only when the signal information matches the characteristics of glass breakage will the detector trigger an alarm. The 3 x 3 signal processing algorithms enable the GS930 detector to automatically adjust to environments.
