DSC Wireless Universal Door Contact - with Built-in Reed Switch, 433MHZ


Regardless of the application, the compactly designed WS4945 wireless door/window contact should be every installer’s first choice for toughto-fit installations. The contact has become the new DSC standard for door/window contacts due to its streamlined profile (30% smaller than its predecessor the WLS925L-433/WLS935L) and new design that allows for double-sided tape mounting.
