Accordion Fire Protective Curtain DSI-A4HR
The Accordion model DSI A4HR is DSI’s answer to four-hour protection as a barrier against fire and smoke. This fire protective curtain does not need extra hardware such as corner posts, runners, or other stabilizing hardware to ensure that it keeps its shape while in its working position.
This design is meant to be a customizable solution for tricky openings such as atriums, escalators, stairwells, or other types of oddly shaped throughways. The provided protection is achieved through the blend of fiberglass woven fabric that is heat-rated, and the latest in reliable gravity fail-safe technology.
This is an advanced system meant to blend in with the surrounding structures, adding to the visual appeal of a space. It is also equipped with an automatic retract system for after the emergency has been dealt with. Incorporating the most cutting-edge tech in the industry, the DSI A4HR stands alone in efficiency and cost-effectiveness.
