Crow GBD Plus – Compact Glass/Shock

GBD-PLUS Shock & Glass Break

The GBD-PLUS is the ultimate answer for all those tired of false alarms. It listens for sounds of
breaking glass, which produce two sequential signals of different frequencies .The unique phased
frequency detection circuitry of this detector allows detection of both shock signal and the strong signal
of glass breakage creating a “false alarm free ”glass break detector. The detector does not need to be attached to the window, providing volume protection, and allowing you to protect several windows with one detector
