Abstract
This invention relates to a fire barrier which includes a functional combination of at least one single-panel casement panel and a sliding panel which is connected or adjacent to it. The sliding panel, which can be automatically moved horizontally during normal operation, contains an auxiliary drive mechanism which, in an emergency, moves the sliding panel without an outside power source into the open position. The casement panel is moved simultaneously by a closing mechanism from its fixed or open position into the correct closed position to create or act as a barrier.
