Standard Smoke Curtain incorporating fiberglass fabric.

DSI-HHS10B Hose Stream Rated Horizontal Fire Curtain

The DSI Hose Stream Rated Horizontal Fire Curtain Model DSI-HHS10B allows architects to compartmentalize large floor openings and reduce or eliminate mechanical smoke evacuation systems. A solution to design challenges of preventing smoke and fire from spreading through the ceiling and atrium voids, stairwells, and skylights.

The DSI Hose Stream Rated Horizontal Fire Curtain consists of a light gauge compact steel headbox that houses the roller, fabric, and motor within the casing to create a small package that remains virtually invisible until deployed. The curtain consists of a light weight proprietary multi layered fire rated fiberglass/ stainless steel fabric and slim steel side guides.

The DSI-HHS10B Horizontal Fire Curtain incorporates the cutting edge technology of our UL 10D curtain products but with the advantage of being tested and labeled to 2 hours UL 10B with Hose Stream.
