摘要： A method and apparatus for rapidly and reliably sealing off a selected exit way or entrance way from an adjacent path of smoke which comprises providing a reel of fire resistant material and having magnetic edge strips on each side thereof above said exit way or entrance way, and causing the reel to drop in vertical fall adjacent to the exit way or entrance way and simultaneously cause magnetized strips on a fire retardant curtain wound on the reel to become rapidly and magnetically attached to the exit way or entrance way upon the nearby condition of either smoke or fire. This apparatus is elegantly simple and reliable in both its construction and operation and has an extremely high price/performance figure of merit.
