FIRE & SMOKE CONTROL DOOR ASSEMBLIES
Vertical Rolling Steel Doors, Models - CFS, FSFD, FSFD-IS Insulated, FSFD-STC Acoustic, and Dynamic 110F, for installation as a Fire & Smoke-control door assembly and Model FSFD-TR for Temperature Rise. May incorporate vision panels.
The Auto Set Fire Door (3" Flat Slat), Insulated Fire Door (Insulated Profile), Acoustic Fire Door (Acoustic Profile), Auto Set Fire Shutter (1-1/4" Profile), and Dynamic 110F (F3D Profile) are fire rated for 4 hour, 3 hour, 1-1/2 hour, 1 hour, and 3/4 hour per UL 10B when supported by a masonry, gypsum-protected CLT (see limitations below), or gypsum with structural steel stud wall.
For 4 hour and 250 or 450 degree temperature rating two Insulated Fire Door assemblies shall be installed back to back (see details below):
FSFD-TR temperature rise rating of "Less then 650 degrees" when used singly on one face of the supporting wall, a temperature rise rating of "Less then 450 degree" when installed back to back on both faces of the supporting wall, and a temperature rise rating of "Less then 250 degree" when installed back to back on both faces of the supporting wall with a minimum wall thickness (air gap) of 13 inches between the doors.

aThese assemblies were evaluated without the use of an artificial bottom seal. When installed with the manufacturer-provided brushes and neoprene bottom seal, they may be installed in areas where pressurization is provided to control smoke movement in accordance with Section 4.3.2 of NFPA 105 and for hoistway opening protection and lobby doorways as allowed in Chapter 30 of the IBC. For installations exclusive of hoistway opening protection and lobby doorways, and where pressurization is not used to control smoke movement, seals at the bottom edges of the assemblies are optional.

INSTALLATION LIMITATIONS
Assemblies may be installed in gypsum with structural steel stud framing, masonry, or gypsum-protected Cross Laminated Timber (CLT) walls. When installed in gypsum-protected CLT walls, the following conditions apply:
- Supporting CLT wall must be fire-resistance-rated in accordance with the code.
- Noncombustible protection shall be in accordance with the code, but not less than:
- Two layers of 5/8-inch Type X gypsum per face for walls required to have a fire-resistance rating of 2 hours or less.
- Three layers of 5/8-inch Type X gypsum per face for walls required to have a fire-resistance rating of 3 hours or more.
- Fire-protection ratings for assemblies installed in CLT shall not exceed 3 hours, regardless of maximum assembly rating when installed in masonry construction.
- Assemblies bearing a fire-protection rating of 90 minutes or less shall be designed with an additional sacrificial 1 inch of anchorage embedment depth or be through-bolted.
- Assemblies bearing a fire-protection rating of 2 or 3 hours shall use through-bolted anchorage.
