Short title	Static closure in stopped air and dynamic closure against fan pressure.
Image title	Top, static: the fan is stopped and there is no airflow; a fusible link releases the damper blades, which close in still air. Bottom, dynamic: the fan keeps running, air flows along the duct and presses on the closing blades; a remote activation signal triggers closure, which must overcome the airflow and pressure.
