Take your QS-1112-P01 mini-door and window contact, remove all the contents from the box carefully. The box should contain the magnet, sensor, packet of adhesive and most important the instructions. Next, you will begin to put the adhesive on the sensor and the magnet, then pull off the battery tabs. Now you are ready to install it. Before you install the QS-1112-P01 mini-door and window contact make sure you pull off the adhesive, clean the mounting surface with rubbing alcohol and apply the sensor on the door frame and the magnet on the actual moving part of the door/window. Please make sure you have the magnet lined up with the triangle as shown in the video. You will also notice there is a knockout on the back of the QS-1112-P01 mini-door and window contact. Screw that part into the wall so if someone attempted to pull the device off the wall it will trigger a tamper the alarm.
