A lock sensor detection system for detecting when a door latch assembly is in a locked condition and in engagement with a door jamb includes a circuit having an open and closed condition. The circuit is in the closed condition when the door latch assembly is in the locked condition and in engagement with the door jamb. An actuator, preferably a magnet, is adapted to be disposed in the door jamb for actuating a circuit, preferably a magnetic circuit, when the circuit is in the closed condition and the door latch assembly engages the door jamb. A signal emitting component is disposed within and operatively connected to the door latch assembly for providing a signal in response to the circuit being in the closed and actuated conditions indicating that the door latch assembly is in an engaged and locked condition.
