Elevator Smoke Curtain

Introducing the DSI 600 Elevator Smoke Containment System®

A cost effective and architecturally pleasing solution to elevator shaft smoke protection. A proven system that meets all code requirements.

Unlike other products on the market, the DSI 600 elevator smoke containment system is also fire rated. 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. The DSI 600 system also has OSHPD approval and has Los Angeles City Fire Department acceptance for high rise applications.

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 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.

This insures easy access from either side of the elevator cab in an emergency situation. When the button is depressed the curtain will automatically deploy back down to the closed position until the fire alarm is cleared.

Low profile side guides ensure against movement or blowout during extreme pressures caused by fire conditions. The technologically advanced fire resistive fabric is concealed in a compact overhead housing that takes as little as 7 1/2′ of headroom. It is virtually invisible when in the retracted position.

Custom sizes available for any elevator size.

Elevator Shaft Pressurization vs Elevator Smoke Curtains

There are basically two methods for smoke containment. Shaft pressurization is achieved via fans pressurizing each of the elevator that mechanically pump the smoke from the building allowing occupants to evacuate. This can be an expensive method of design. Another method would be build a smoke barrier area or method that prevents the smoke from migration and spreading. Primarily, protecting the elevators shafts from upward migration of smoke to the upper floors.

Smoke curtain elevator protection

Buildings 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. Elevators can act like a chimney and allow smoke to seep and quickly spread to other floors. 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. However, the enclosed elevator lobby area can take up lots of prime space and can be challenging to the design process.

Why elevator smoke curtains are the better choice

Elevator smoke curtains create a smoke barrier system for buildings that comply with smoke and fire codes. 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. Design wise this returns valuable space for the architect to work with and can be completely hidden.

  • A proven system with over 30 years of manufacturing experience
  • Extremely compact with as little as 7 ½” of headroom required
  • Fail safe design with automatic reset after a fire alarm
  • Battery backup system standard
  • Runs on a 24-volt system for lower electrical installation cost
  • Lightweight design requires no heavy structural support
  • 60-minute fire rating standard with option for 180-minute rating
  • Multiple egress options
  • Vison lite option
  • Unlimited size options available
  • Multiple mounting design options
  • Complies with all relevant local and national codes

Elevator Fire Rated Smoke Curtains Testimonial

6/20/17

Dear Door Systems,

We have your DSI-600 Elevator Fire Rated Smoke Curtains installed on both our Maxfield lofts and Garment lofts high rise buildings in downtown Los Angeles. From the very beginning the elevator smoke & fire curtains have been working wonderful. We are very happy with the system and have had no issues. I don’t think we could have done better with any other company or product. I have and will continue recommending your company for future work on our properties.

Sincerely,

Alex Hernandez

Elevator Smoke Curtains Testimonial

4/18/2015

To whom it may concern,

I have DSI 600 Elevator Smoke Curtains installed in one of my high-rise buildings here in downtown LA but in the future, I would like to install them in others. Unlike other elevator fire rated smoke curtains we have used in the past, the DSI 600 Elevator Smoke Curtains all come down at the same time in a controlled rate of decent and require a no effort to reset. The DSI 600 system works every time.

The thing that surprised me most is that the elevator shaft smoke protection curtains are so concealing and you would never know they were there. This is important to landlords and architects looking to use a system that works yet blend in with the surroundings.

The Door Systems staff does a great job and are very attentive. I would recommend Door Systems and the DSI 600 Elevator Smoke Containment Systems to any landlord or operations manager in need of a smoke and fire rated containment system.

Sincerely,

Philip Hernadez
Operations Manager at The Swig Company

DSI Overhead Coiling Smoke Curtain with Vision Lite Option

 Door Systems Model DSI-600 Elevator Smoke Containment System offer gravity fail safe performance. The curtain remains virtually invisible in the retracted position within the compact head-box. When signaled by a local detector or fire alarm system, the curtain descends to the operational level using the gravity fail safe system. 

ADVANTAGE: 

The addition of the Vision Lite into our elevator smoke containment system, will satisfy section 2.11.6.3 (d) of the ASME A17.1 Elevator code. When in the closed position, the addition of the vision Lite allows fire fighters to visually observe the elevator landing (lobby) when the elevator hoist way door is no more that one-quarter open.
