Abstract
An automated door closure system regulate the release and closure of a door in a door assembly that includes a primary door, a secondary door, and a door frame. The system includes a door closer, a control unit, and an automatic input sensor. The door closer, which is connected between the secondary door and the door frame and includes a cylinder and an operating rod, biases the secondary door toward a closed position. The control unit includes a motive device and a rod catch element. The rod catch element, which may be moved by the motor, is positioned in proximity to the operating rod to adjustably prevent the secondary door from being closed. The automatic input sensor detects a door assembly use condition. The control unit controls the motive device based on the detected condition to move the rod catch element, allowing the door closer to close the secondary door.
