Abstract
A device for inhibiting the closing of a door that controls entry of an enclosure includes a first magnet disposed on a driven portion of the device and a second magnet disposed on a fixed portion of the enclosure. The first magnet and the second magnet are configured to be in register with each other as the door moves toward a closed position such that if the first magnet and the second magnet are in register with each other, a pole of the first magnet is in close proximity of a pole of the second magnet such that the first magnet and the second magnet react to each other to inhibit motion of the door towards the closed position.
