The Home Glass Break Detector is a two-stage detector designed to detect the “thud” of an object hitting the glass, and the breaking of tempered, coated, plate, and multi-pane glass. Place the sensor up to 1000ft away from the tattletale base unit. When used with our High Performance Wireless Signal Booster you can add another 1000′ of range. A supervised sensor, the Glass Break Detector will notify the tattletale of an alarm event, low battery, lost signal, tamper & sensor bypass.
