Alarm Sensors ? broken glass
Broken glass sensors react ringing in the fragile glass. The most sophisticated models analyze range of audio noise in the room. If the spectrum contains a noise component, coinciding with the spectrum of injury glass, the sensor is triggered. One such sensor can protect glass windows, showcases, etc., an area of 10 m2. Dvuhporogovye sensors record the sound of impact glass, and bell-breakable glass. To display this alert sensor should register two related signal at intervals of not more than 150 ms. The sensitivity of the sensors of broken glass is governed by the application of the simulator break glass
