A door position monitoring mechanism mounted in the edge of a door that senses whether a door is opened or closed by sensing the absence or presence of a magnetic field of a magnet that is mounted in the door frame. Information regarding the door position is then transmitted to a battery operated wireless access control system mounted on the same door through wires extending from the door position monitoring mechanism.
