The ELK-6040 Wireless Glass Break Sensor is designed for use with Elk’s two-way wireless product line consisting of the ELK-M1XRFTW Transceiver and the ELK-M1 Control. The 6040 listens for actual patterns of breaking glass across the full audio band using Pattern Recognition Technology™. The factory set recognition patterns make it possible to detect the difference between breaking glass of framed perimeter windows in a building vs. a drinking glass breaking within a room.
