GENERAL

This category covers exit hardware devices for swinging fire doors, which are intended to facilitate the safe egress of persons in the case of emergency, as well as provide fire protection for door assemblies. They have been investigated from the standpoint of fire and panic protection.

Fire-exit hardware of the single-point-latch type (mortise or rim devices) with 3/4-in. latch bolts and the vertical rod type (surface mounted or concealed devices) and mullion assemblies are intended for use on fire doors having a rating up to and including 3 h (unless otherwise noted in the individual certifications). In general, fire-exit hardware devices are intended for use on hollow-metal, composite (steel, wood, or plastic-covered), sheet-metal, wood core and metal-clad (Kalamein) type fire doors. Fire-exit hardware of the single-point-latch type (mortise or rim devices) are intended for use on swinging doors not exceeding 4 ft in width and 8 ft in height. Mortise-type fire-exit hardware devices can be used on the active door of doors swinging in pairs in openings not exceeding 8 ft in width and 8 ft in height (unless otherwise noted in the individual certifications).

Vertical-rod-type exit devices are intended for use on swinging fire doors mounted in pairs, wherein one door of the pair is equipped with a mortise-latch-type exit device. Both doors of a pair may incorporate vertical rod devices as indicated in the individual fire door certifications. See the individual fire door certifications for manufacturers eligible to provide doors swinging in pairs (same direction) equipped with vertical rod devices and without an astragal, and double egress doors.

Fire-exit hardware devices are intended to be installed in accordance with the installation instructions packaged with the device. The use of sex bolts or through bolts to mount the devices to the door is required for composite (wood or plastic-covered) and wood-core-type fire doors unless an alternate mounting method is identified in the individual door manufacturer's certifications (and installation instructions). The use of sex bolts to mount the devices to the door is required for steel-covered composite type, sheet-metal type or hollow-metal-type fire doors provided without reinforcements. The use of steel machine screws to mount the devices to the door is required for steel-covered composite type, sheet-metal type or hollow-metal-type fire doors incorporating steel reinforcements.

Doors prepared at the factory for this hardware bear the marking, "Fire Door to be Equipped with Fire Exit Hardware."
