Click image to open expanded view


Among the smallest wireless door or window alarm contacts currently available the wafer-thin profile of the EV-DW4975 provides a streamlined practically non-existent look once installed. The wireless alarm 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 the door or window warranties. A generous alarm magnet gap of 5/8" 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 alarm receivers.

The EV-DW4975 wireless vanishing door and window alarm contact has a depth of 3/16" making it virtually invisible when mounted on a white door or window frame. Use the EV-DW4975 for the most aesthetically pleasing wireless security system installations. Significantly smaller than competitor wireless door and window alarm contacts the EV-DW4975 is housed within a compact casing that allows it to be used for the tightest-fitting installations. Once installed the wireless alarm contact is inconspicuous and complements the decor of most homes.
