The 5810 series acoustic glass break sensor combines high false alarm immunity and excellent detection by recognizing the exact frequency pattern generated by glass breaking. Instead of listening for a loud sound at one or two characteristic frequencies, the 5810 series listens at 30 points across the glass break frequency spectrum. This not only enables it to discriminate common false alarm sources, but also ensures detection of even the quietest of breaks so it can be used with blinds or light curtains. The 5810 series are recommended for perimeter loops and is designed to function in occupied areas. In 24-hour loop applications, where the detector is armed all day and all night, the false alarm technology will be pushed to its limit. Some sounds can duplicate the points on the glass break pattern that the 5810 series detects. Install the sensor on a perimeter loop that is armed whenever the door and window contacts are armed. The false alarm immunity is best in rooms with only moderate noise. For 24-hour occupied area protection, use Sentrol shock detectors. The sensor may not consistently detect cracks in glass or bullets that break through the glass. Glass break detectors should always be backed up by interior protection.
