The ShatterPro 3 is the latest breakthrough in GE Security's advanced series of acoustic glassbreak sensors. In independent lab tests, the ShatterPro 3 provides 25% better false alarm immunity than industry leading glassbreak sensors*. The coverage pattern can be easily adjusted to fit small or large rooms. Interference outside the range will not cause false alarms. The ShatterPro 3 detects in a full 360° coverage pattern, with a maximum 25' (7.5m) radius from sensor to glass. Using our patented Pattern Recognition Technology, the sensor listens for actual patterns of breaking glass while eliminating most false alarm patterns. ShatterPro 3 listens across the glassbreak frequency spectrum for greater false alarm immunity. Available with a round or rectangular housing. ShatterPro 3 can be tested without opening the sensor by activating the hand held glassbreak tester at close range. A simple hand clap feature lets end users confirm at any time that the ShatterPro 3 is operational.
