SD60 Deployable Draft Curtain

SD60 Deployable Draft Curtain - 143014345601 SD60 Deployable Draft Curtain - Smoke-Baffle

Applications:

  1. Monumental Stairway to replace glass smoke baffles

Description:

Deployable draft curtains are considered "smoke partitions" in the IBC. There is a requirement for a smoke baffle with sprinklers 6-feet on center. The fabric curtain will deploy on smoke detector or fire alarm activation to 18 to 24-inches below ceiling. The curtain is fire rated thus there is no need to have sprinklers 6-foot on center to deluge the curtain. Since glass baffles (draft curtains) are 18-inches in height per NFPA 13 then the Deployable draft curtain is also designed to be 18 to 24-inches in height.

The U.S. Smoke & Fire -- SD60® Deployable Draft Curtain is a UL Listed gravity fail-safe deployable automatic smoke draft curtain that provides channeling of smoke from open stairwells, escalator openings, and other floor openings.

If your project requires a longer drop height, then the model number would be the SD60® smoke curtain, please refer to that product page.

Technical Information:

  1. Robust Construction- Headbox manufactured 18-gauge steel, all glass textile with polyurethane coating- The complete assembly is listed which is the headbox, fabric, motor and bottom bar.
  2. Accessible Maintenance- Removable bottom cover plate of headbox at ceiling for access to the low voltage motor and fabric.

  4. Multi-Roller Head Box Types and Sizes- 10-inch by 6-inch (under and over roller) type or 6-inch by 10-inch (side by side roller). Depending on the space in the plenum, selection will be based on space constraints above ceiling
  5. Length - Length 984 feet
  6. UL 864 listed Battery Back Up- Standard 2 12-volt batteries in UL 864 listed Control Panel and Motor Controller typically 40-feet away from Curtain head box for 14-2 low voltage wiring, 12-2 low voltage wiring for 80-feet away from Curtain headbox.
  7. Control Panel -- connected directly to Addressable Fire Alarm system by closed contact that opens on fire signal from Smoke/IR detector. The contact type must be volt free, dry contact. Each Control Panel draws 7 amps. Control Panel requires 120 volt, typically a 20-amp circuit breaker. The circuit shall be a dedicated circuit marked life safety. Each control panel can control 4 motors. Each curtain roller utilizes 1 motor. If the curtain requires up to 8 motors, then a second Control Panel will be wired in series. If the curtain requires 12 motors, then a third Control Panel will be wired in series. Up to 9 Control Panels may be wired in series.
  8. Smoke Detector Activation- the Smoke/IR detector wiring can be wired directly to the Control panel if there is no central fire alarm system in the building.

FREQUENTLY ASKED QUESTIONS (FAQ):

Does the fabric come in various colors?

The fabric comes in gray only.

Does the headbox come in different colors?

Yes, Ral colors, white, gray, black standard and all other Ral Colors optional. USSF recommends factory-etched primed and paint in field so that the sheen will match better.

Do I need side guides?

No, the curtain edge will be 1-inch from the wall and the maximum standard for draft curtain from wall edge is 1-inch.

What is the drop speed of the smoke curtain?

NFPA 80 Chapter 21 Fire Protective Curtains states that drop speed must be 6-inches to 24-inches per second.

Does the curtain automatically reset when the smoke/IR detector or fire alarm system reset to normal non-alert mode?

Yes, the system is automatic, once the closed contact from FAS opens, the curtain drops to its operational position and when the FAS contact closes, the curtain motors engage, and curtain retracts back into its headbox.

What are the pros and cons of a deployable draft curtain vs the fixed in place glass draft curtain baffle?

Aesthetic of having a more clean and open design unencumbered by fixed glass. Further, headroom is also a consideration on a monumental stairway for a tall person to not hit their head on fixed in place glass that is always there.

Can the deployable draft curtain be an L shaped 90-degree angle or any obtuse angle?

Yes, the opening between the two curtains at the angle will be less than approximately 1-inch.

Can the deployable draft curtain have no gap whatsoever at the 90-degree angle?

Yes, USSF can utilize our accordion curtain design for all-fabric corner so there is no gap.

Dr Steven S. Sadeghian CEO, U.S. Smoke & Fire
Our Featured Work: H&M Stores
"U.S. Smoke & Fire provided a unique solution that met safety codes without visually disrupting our space."
We challenged U.S. Smoke & Fire to provide a solution to the open architecture design in our flagship store. We needed a system that could make angles and turns without corner posts. Working with Underwriter Laboratories, U.S. Smoke & Fire customized Automatic Deployable SD240A Fire Curtains to use in place of Fire Rated glass. Because of their professionalism, proactive attention to detail, and expert execution, we use them in our other H&M facilities across the nation. I highly recommend U.S. Smoke & Fire for any curtain project.
