Abstract
A system for determining a state of a door having a locking mechanism for locking the door includes a locking mechanism and a door sensor. The locking mechanism sensor is disposed for sensing a condition of the locking mechanism and generating a signal indicative thereof. The door sensor disposed for sensing a condition of the door and generating a signal indicative thereof. The system further includes a processor for determining a state of the door, in response to the signals from the locking mechanism sensor and the door sensor. The state of the door is a secured state when the door sensor senses the condition of the door as closed and the locking mechanism sensor senses the condition of the locking mechanism as locked. A method for determining a state of a door having a locking mechanism for locking the door includes sensing a condition of the locking mechanism and sensing a condition of the door. The method further includes, determining a state of the door as a secured state when the condition of the locking mechanism is sensed as locked and the condition of the door is sensed as closed.
