Abstract:
A system for determining the position of a bolt in a door including a locking mechanism for moving the bolt between a first locked position wherein the door is secured in position within a door frame and a second unlocked position wherein the door is moveable within the door frame. The position of the bolt is determined by a determining means and a signal indicative of the position of the bolt is generated. A transmitter is connected to the determining means and transmits a signal to a means for indicating to a user the position of the bolt. The indicating means includes a processor and receiver and wherein the transmitter transmits the signals generated by the determining means and the receiver receives the signal and provides the signal to the processor for determining the position of the bolt and generating a signal indicative of the determination.
