The recessed electric door opener is a device that is installed in the door frame to control its opening from a remote place by means of an electric device. In an electronic door entry system it is possible to activate the door opener of the entrance to the building and allow access to the visit from the telephone or monitor of the house by pressing the "door opener" key. A recessed door opener is composed of an electrical mechanism and an armature.
