The GBD-II is the perfect answer for all who are tired of false alarms. It listens for the faintest sound of breaking glass which emits two different sequential signals of seperate frequencies. The exclusive phased frequency monitoring circuitry of this detector allows for detection of both shock signal and the strong breaking glass transmission of glass breakage producing a "false alarm free" glass break sensor. The detector requires no window attachment, providing volume protection and permitting you to protect several differentwindows with one detector.
