For mounting your Garage Door Sensor make sure to place it near the top of the door on a clean solid surface. I would recommend not placing the sensor on a metal surface, unless you have to. You will notice there are 4 small lines at the bottom front of the sensor. When placing it, make sure to have the lines facing downward to get the appropriate response.
Once you have found the area you wish to mount the sensor, you can use double sided stick tape on the back of the sensor and apply pressure on the garage door for about 10 seconds with the tape inserted. You're done with the mounting.
Adding The Sensor To Your Security System

Note: When the panel asks you to "Trip Sensor" you can take off the cover of the sensor and it will send a signal to the panel (If this does not work, try removing the battery and putting it back in).
