The automatic resetting S4000 is a side coiling smoke and fire door. The S4000’s side activated design makes this product ideal for openings in rated walls where headroom is limited and enables the door to navigate around tight curves and contoured openings.
S4000 fire door / fire shutter systems are ideal for schools, hospitals, casinos, retail and museums, or any finished area. The S4000 provides a solid solution for fire protection in area separation walls, occupancy separations, and corridor separations.
Model S4000 is available without a floor track.
This technology is the subject of US Patent Nos. 8,307,877 and 9,267,326.
