Details For This Fire Door

The curtain consists of interlocking slats that are cold rolled formed from hot dipped galvanized steel, optional baked on gray polyester enamel coating, or 304 stainless steel with a number 4 finish curved profile (SC3) or flat profile (SF3). Each end of the alternate slats are to be assembled with end locks to maintain slat alignment and to act as a wearing surface inside the door guides. The slats are designed to withstand windloads of 20 psf. The windlocks are furnished for greater windloads and upon request(consult the factory). The slat thickness shall be calculated with U.S. gauging with a minimum of 20ga. for doors up to 20 feet wide and 18ga. for wider spans. The steel slats are to be hot dipped galvanized as per A.S.T.M. A653. Each curtain shall receive a bottom bar to maintain slat alignment and posture.

The bottom bar shall consist of two steel shop primed angles a minimum ⅛ inch thick.

The spring counterbalance is to be housed in a steel pipe of the appropriate diameter and the wall thickness is to support the curtain. The deflection shall be limited to a maximum of .03 inch per foot of door width. The springs are to consist of helical torsion type of design to meet a 25 percent safety load factor. The safety factor allows for safe operation, ease of use, and longer spring life. The springs are to be grease packed and anchored, using a cast iron anchor, to a cold rolled steel inner shaft. The spring tension shall be fully adjustable from outside of the end bracket plate. To ensure smooth operation, the end bracket plates shall contain sealed ball bearings to minimize the wear of the pipe shaft.

The drop mechanism consists of a viscous speed governor, which controls the door’s rate of descent in the emergency mode. The viscous governor is self adjusting and provides a smoother and quieter rate of descent within the NFPA 80 specification of 6 inches to 24 inches per second. The automatic drop mechanism may be activated by a fire alarm, smoke or heat detector, or a melting fuse link at 165 degrees Fahrenheit (74 degrees Celsius)

The end bracket plates shall consist of the steel plate of no less than ¼ inch thick. The bracket plates are to house pipe shaft and the counterbalance assembly. The shaft is attached to the plate by sealed ball bearings fitted onto the plate.

The guides shall consist of a minimum of 3 inches of structural steel angles and a minimum of 3/16 inch thick. The guide depth shall be of a length adequate to provide for proper slat penetration.

The hoods shall consist of a minimum of number 24 gauge hot dipped galvanized steel. The hoods are designed to protect and house counterbalance assembly. To prevent hood sag, intermediate supports shall be furnished as required.

The locking for manual and chain operated doors are to be slide bolts mounted on a bottom bar with provisions for padlocks. The gearing within are motors to be self-locking.

The finish for all non-galvanized surfaces shall receive a shop coat of rust inhibiting primer. The field painting is not included in this section.

Installation is to be by USP or by an authorized dealer.
