USE AND INSTALLATION

This category covers freight elevator fire doors of the single-swing or counterbalanced type. The doors consist of either formed-steel sheets, hollow-metal, or metal-covered wood units. The counterbalanced door assembly includes the door panels, frame (optional), guides, latching device, and counterbalance mechanism.

Freight elevator doors are intended to be installed in concrete and masonry walls, unless otherwise noted in the individual certifications.

Swinging-type freight elevator doors are intended to be installed in certified door frames (see Fire Door and Fire Window Frames [GVTV]).

Hoistway doors for elevators are intended to be installed in accordance with ANSI/NFPA 80, "Fire Doors and Other Opening Protectives," and ANSI/ASME A17.1, "Safety Code for Elevators and Escalators."

Counterbalanced-type freight elevator doors may be installed in concrete and masonry walls without a frame. Counterbalanced-type freight elevator doors may be installed in nonmasonry walls and in concrete or masonry walls with the frame supplied with the door assembly or in a certified frame (see GVTV) as indicated in the individual frame certifications. When a frame is used with counterbalanced doors, it should be installed in accordance with the installation instructions provided with each door assembly to provide the protection indicated.

Authorities Having Jurisdiction should be consulted before installation.

CERTIFICATES

Freight-elevator-type fire doors exceeding the heights eligible for certification and which have not been subjected to the fire tests in ANSI/UL 10B can be provided with a Certificate for Oversized Door Assemblies that are otherwise found to be in compliance (except for size) with all requirements for design, materials and construction. These oversized door assemblies are intended for use with specific frames. Authorities Having Jurisdiction should be consulted as to whether the assembly is acceptable for a specific location. The Oversize Certificate can be a separate certificate or a label certificate affixed to the assembly.
