ISW BGB1-SAX WLSN GLASS BREAK DETECTOR
The wLSN Glassbreak Detector is a wireless sensor device that detects breaking glass. It is equipped with two tamper switches and four glassbreak sensitivity settings.
Functions:
Dual Acoustic Technology
When an object hits a pane of glass, the glass absorbs the blow and emits a low frequency sound pressure wave, called the flex wave. When the force of the blow is too great, glass shatters and emits a high frequency audio signal. A bell ringing or a vase breaking produces a similar audio signal, but does not produce a flex wave. The wLSN Glassbreak Detector detects the flex wave first and the audio signal second, reducing false alarms from items that only emit high frequency audio signals.
Glassbreak Sensitivity
Use the convenient DIP switches to select a sensitivity setting. There are two attack mode selections with multiple sensitivity settings.
