This ultra-thin glass break detector features a built-in window/door alarm that activates when the window or door glass breaks or when the door/window is opened. With the switches on the side of the alarm unit, you can turn it on and off as needed and adjust the detection sensitivity. The slim profile makes it ideal for mounting on a window or door. The alarm unit requires 2 x CR2032 batteries (included) with an average lifespan of one year. The alarm unit provides a warning when the batteries are nearly depleted, and you can press the "Battery Test" button at any time to check the status of your batteries. No tools are required for the alarm unit: it has magnetic sensors and comes with double-sided tape (included). Simply stick the alarm unit onto the glass of the door or window and place the magnetic sensors on the door or frame, and you're done.
