A method and apparatus according to various aspects of the present invention is configured to automatically reset a rollable
fire door curtain in the raised position. In one embodiment, a
brake is coupled to a rolling
fire door axle by an electromechanical
clutch. The
fire door is pre-disposed to unroll and close the opening, however, the
brake prevents the door from unrolling. When a switch, a
signal, or a
fusible link indicates that the fire door should close, an electromechanical circuit board sends an electrical
signal to an electromechanical
clutch which opens the
clutch. With the clutch open, the
brake is no longer coupled to the fire door and the door closes. When the switch or
signal is reversed, the clutch closes, re-
coupling the fire door axle to the brake. The brake allows input rotation in both directions, but prevents the rolling door from closing under its own weight. Therefore, upon raising the curtain, the fire door is automatically reset and ready to close in the event of a fire.
