Door and window sensors come in two pieces. One fits onto the door or window itself, while its counterpart attaches to the frame. Adhesive usually keeps the sensors in place, though sensors can be screwed directly into the frame. Position the two pieces of the sensor right next to each other, because they interact. When the two pieces are separated, such as when the door or window is opened, they send a signal to the alarm panel.
