Security detectors: Glass break sensor
DG-50 detector is an acoustic glass break detector designed to detect the sound of a broken window glass. The DG50 detector has a multi-level signal processing circuitry to maximize the likelihood of breaking glass and minimize the level of false alarms from natural noise. The detector DG-50 is resistant to the sound of blows, does not respond to the closing of doors and even to blows to the body.
