ABSTRACT:
An electrically operated drop seal assembly for a pass door in an operable wall. The drop seal assembly includes an actuator which is selectively movable by a motor between a first position and a second position. The assembly also includes a retractable drop seal which is movable between a retracted position spaced from the floor over which the pass door is suspended and a sealed position in sealing engagement with the floor. A coupling of the drop seal assembly converts movement of the actuator from the first position to the second position into movement of the retractable drop seal from the retracted position to the sealed position. The assembly also includes a pass door opening activated retractor for raising the retractable drop seal from the sealed position when the pass door is moved relative to the operable wall from a closed position to an opened position.
