The DSI 600 Elevator Smoke Containment System from Door Systems Inc is a cost effective, architecturally pleasing elevator smoke containment system. Unlike other smoke containment systems, it is UL10D listed with a 60 minute fire rating to provide not only UL1784 smoke protection, but fire protection as well. <br /> <br />This system is well concealed and virtually invisible when in the retracted position. The DSI 600 smoke screen works on gravity fail-safe technology that requires no power to close, and is fully synchronized with the building's fire and safety system. <br /> <br />For more information, visit http://www.doorsysinc.com.
