How do I mount my Garage Door Sensor?

To mount the Garage Door Sensor you needs place it in the top-middle portion of the garage door.  Ensure the sensor is setup as follows:

• Make sure the garage door is closed, the surface is clean and dry, and the control panel is less than 100 ft. from the door. 
• Position the sensor on the top of the inside of your garage door in a vertical orientation with the long sides on the left and right and the shorts sides on the top and bottom.  It does not matter which of the two short sides is on top or bottom as the sensor will work in either orientation.
• If you have a paneled garage door, place the Sensor either at the bottom of the top panel or at the top of the second panel as indicated by the two dots in the diagram below.
