Abstract
A door has a first outer face having an opening therein and a second outer face spaced a predetermined distance apart from the first outer face. A hold open device is located substantially between the first and second outer faces. The hold open device holds the door in an open position. A smoke detector is also located substantially between the first and second outer faces adjacent to the opening. The smoke detector is electrically coupled to the magnetic hold open so that upon detection of smoke, the smoke detector causes the hold open to release the door from an open position to a closed position.
