Design wise this returns valuable space for the architect to work with and can be completely hidden. Installing an elevator smoke containment system for smoke and prevention can be done very easily and will eliminate the need for an enclosed elevator lobby. Why elevator smoke curtains are the better choiceĮlevator smoke curtains create a smoke barrier system for buildings that comply with smoke and fire codes. ![]() However, the enclosed elevator lobby area can take up lots of prime space and can be challenging to the design process. Therefore, per IBC requirements, buildings must be designed with elevator smoke protection either by a lobby or an elevator smoke curtain containment system that protects each elevator shaft. Elevators can act like a chimney and allow smoke to seep and quickly spread to other floors. Smoke curtain elevator protectionīuildings with more than three stories are required by the IBC (International Building Code) to be designed with fire and smoke curtain protection systems for all the elevators. Primarily, protecting the elevators shafts from upward migration of smoke to the upper floors. Another method would be build a smoke barrier area or method that prevents the smoke from migration and spreading. This can be an expensive method of design. Shaft pressurization is achieved via fans pressurizing each of the elevator that mechanically pump the smoke from the building allowing occupants to evacuate. There are basically two methods for smoke containment. It is virtually invisible when in the retracted position.Ĭustom sizes available for any elevator size.Įlevator Shaft Pressurization vs Elevator Smoke Curtains The technologically advanced fire resistive fabric is concealed in a compact overhead housing that takes as little as 7 1/2′ of headroom. Low profile side guides ensure against movement or blowout during extreme pressures caused by fire conditions. When the button is depressed the curtain will automatically deploy back down to the closed position until the fire alarm is cleared. This insures easy access from either side of the elevator cab in an emergency situation. The DSI 600 elevator smoke containment system by Door Systems ®, incorporates a battery back-up feature with an emergency curtain up button located on both sides of the elevator cab. The smooth controlled descent of the DSI 600 elevator fire rated smoke curtain system works on a gravity fail safe technology that requires no power to close and is fully synchronized with the building’s fire and life safety system. The DSI 600 system also has OSHPD approval and has Los Angeles City Fire Department acceptance for high rise applications. The DSI 600 system carries a UL10D one hour or two hour or three hour fire protection curtain system label, UL 1784 smoke migration and S label, California State Fire Marshall listing, and ICC-ESR #4761 AC77 compliant. Unlike other products on the market, the DSI 600 elevator smoke containment system is also fire rated. A proven system that meets all code requirements. Allows for egress and access after the system is activated.A cost effective and architecturally pleasing solution to elevator shaft smoke protection.The system can be hidden entirely in a suspended ceiling and will deploy only when needed. ![]() Smoke curtains eliminate the IBC Elevator lobby requirement, providing more space for design freedom.Elevator smoke curtains provide code-compliant smoke and draft opening protection. Flexible magnetic strips are attached to the curtain’s edges to create a tight seal upon deployment. The Elevator Smoke Curtain can be installed almost invisibly in front of elevator openings.ĭuring a fire event, the smoke containment curtain automatically deploys acting as a barrier to prevent smoke from spreading via the elevator shaft. Excessive pressures at some floors to achieve the minimum pressure differentials at all floors.Design of pressurized elevators is complicated and expensive.Elevator shaft pressurization has been approved and adopted for a relatively long time.Here, fans inject large quantities of air into the elevator shaft preventing smoke from entering the hoistway doors. This system is mostly used in tall buildings. Objects can stop the smoke doors from effectively closing when requiredĮlevator pressurization is a code-compliant option for elevator smoke protection and an alternative to enclosed elevator lobbies.They produce limitations for architects and designers.Takes valuable space in commercial buildings.This elevator lobby will be closed by hold open smoke doors ![]() This alternative requires building an extra space at some distance from the elevator to create an elevator lobby. Per IBC, an enclosed elevator lobby shall be provided at each floor where an elevator shaft enclosure connects more than three stories.
