The garage door opener, an Overhead Door “Legacy” model, attaches to the ceiling and door with steel channels. The door is wired to an opener next to the garages rear door that enters the house.  The garage door opener features a pull-cord that will disconnect the motor from the door so that it can be opened manually in case of a power loss.   Two motion sensors are placed about 4 inches from the floor on both sides of the garage door opening to prevent the door from closing on anyone entering the garage as a safety measure.
