DSC EV-DW4975: Wireless Vanishing Door/Window Contact, Built-in Reed Switch, Reliable 433 MHz Technology, Wafer-thin Profile, 16 mm (5/8) Magnet Gap, Lithium Battery Included


DSC EV-DW4975 Wireless Vanishing Door/Window Contact



Among the smallest wireless door/window contact currently available, the wafer-thin profile of the EV-DW4975 provides a streamlined, practically non-existent look once installed. The contact can be easily mounted to a window frame with double-sided tape, eliminating the need for drilling. This not only reduces installation times but also retains the integrity of window warranties. A generous magnet gap of 5/8 (16 mm) easily accommodates larger door or window frames. The EV-DW4975 is built with reliable 433 MHz technology and is compatible with all current DSC wireless receivers.
