The Wireless ShatterPro Series provides excellent false alarm immunity without compromising detection. It is ideal for applications where hard wired acoustic sensors are impractical. The Wireless ShatterPro Series is based on Sentrol s field proven Pattern Recognition Technology, which listens across the glassbreak frequency spectrum for greater false alarm immunity. This allows the sensor to detect breaking glass through blinds and light, unlined drapes. It features a 20 6.0 m range from the sensor to the window. The Wireless ShatterPro Series is suitable for low activity occupied areas on the perimeter loop.
