Abstract
A fire door assembly is provided for covering a structure opening in a sidewall of a structure. The fire door assembly has a roller assembly to be mounted to a portion of the structure defining a portion of the structure opening and a curtain panel disposed on the roller assembly. The curtain panel is operable between a retracted position where the curtain panel is wound onto the roller assembly and an extended position where the curtain panel is unwound from the roller assembly to cover the structure opening. The curtain panel includes first and second panel portions with mutually opposing edge portions in a closed position. A fastener is provided to releasably attach the first and second panel portions to each other. The first and second panel portions are separable from each other in response to an egress force exerted thereon to form an egress through the curtain panel. Upon relaxation or removal of the egress force, the panel portions return to the closed position to close the egress.
