Applications:
- Multi-level Atrium Smoke Control and Containment
- Smoke Zones
- Smoke Draft Curtain to deploy to smoke layer interface which is 6 feet above finished floor or to floor
* **(not the 18" deployable draft curtain, that product model would be the SD60® Deployable Draft Curtain on another product page)
Description:
Smoke Curtains are considered "smoke partitions" in the IBC. The automatic smoke curtain will deploy to the floor or to the smoke layer interface. Smoke curtains do not utilize side guides (rails). As part of an atrium smoke management system, there is a pressure gradient and the one-inch gap from the wall is approximately 20-cfm for a ten-foot drop height which is considered negligible for smoke purge system calculations. The SD60® Smoke Curtain reduces the need for mechanical make up air for smoke purge systems. Make up air would be provided by doors opening on pneumatic openers as part of a smoke management system.
With strategically placed curtains, smoke extraction points and exhaust vents, our systems efficiently control smoke movement. Beyond regulatory compliance, our aesthetically appealing fire protective smoke curtains seamlessly blend into building designs, maintaining the architectural integrity while ensuring life safety.

Technical Information:
- 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.
- Accessible Maintenance- Removable bottom cover plate of headbox at ceiling for access to the low voltage motor and fabric.
- Single Roller Head Box Sizes- 7-inch by 7-inch headbox for single roller system up to 12-feet in length and 10-foot drop height (refer to headbox sizing chart)
- 9-inches by 9-inch headbox for single roller system up to 12-feet in length and 20-foot drop height (refer to headbox sizing chart)
- Multi-Roller Head Box Types and Sizes- 11-inch by 7-inch (under and over roller) type or 7-inch by 11-inch (side by side roller). Depending on the space in the plenum, selection will be based on space constraints above ceiling
- Length and Drop Height Limits- Length 984 feet, Drop Height 45 feet
- 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.
- 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.
- 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):
Can I use the SD60® Smoke Curtain to fire rate an opening since it does not have side guides?
Yes, if the curtain overlaps each opposing wall of an opening by 6-inches. Thus, if you have a 10-foot opening then the curtain must be 11-feet in length. This would be a 20-minute fire rating to UL 10B. If the curtain does not overlap the opening in the wall and there is a gap, then of course there would be no fire rating.
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..
Can the side guides be fully recessed in walls and what is the minimum size?
Side guides are a manufactured steel extrusion 2-inches in width and 4-inches in depth. The side guide can be recessed into the wall cavity typically two to three inches.
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.
Can the SD60® smoke curtain be installed exterior to the building?
Yes, this application is for glass protection.
Can the SD60® smoke curtain cover my house from the roof down to protect my home in the event of a wildfire?
Yes, the curtain can protect the home from embers, but the extent of wildfire could easily overcome any fire protection measures.
Can I use my curtain to deploy and retract by a remote key switch, as I am to use it to close off an area?
Yes, the curtain can be controlled by a remote key switch in view of the curtain to deploy and retract the curtain. There is an optional "door mode" software that will allow the user to deploy the curtain without any beeping of the control panel which would normally beep when the curtain is deployed.
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 the curtain retracts back into its headbox.
