Claim Text:
1. A labeled fire door assembly for covering a structure opening in a structure wall, the fire door assembly comprising: a retracting assembly configured to be mounted to a portion of the structure defining the structure opening; a curtain panel disposed on the retracting assembly and being movable between a retracted position where the structure opening is at least partially uncovered and an extended position where the curtain panel covers the structure opening, the curtain panel comprising: a first panel portion having a first vertical edge portion and a first extended position in which the first vertical edge portion is substantially fixed when the curtain panel is in the extended position; a second panel portion having a second vertical edge and a second extended position when the curtain panel is in the extended position, the first and second vertical edge portions being mutually opposing when the first and second panel portions are in the first and second extended positions, the edge portion of the second panel being moveable with respect to the first portion; a resealable fastener arranged along the entire opposing first and second vertical edge portions of the first and second panel portions and configured to releasably attach the first panel portion and the second panel portion to each other along the entire mutually opposing vertical edge portions, wherein: the fastener is configured to at least partially release the first and second panel portions from each other at any point along the mutually opposing vertical edge portions and a portion of the second panel portion is movable from the second extended position to a third position folded away from at least part of the first vertical edge in response to an egress force exerted on the second panel portion to form an egress through the fire door assembly, and upon relaxation or removal of the egress force, the second panel portion returns from the third folded away position to the second extended position under a force of gravity, and the fastener causes the first and second panel portions to reattach to each other along the first and second vertical edges, to prevent one of fire and smoke from passing through the fire door assembly, at least to a degree indicated by the label.
