ABSTRACT:
An improved fire seal comprises: an elongated flexible carrier incorporating structure for affixing the seal in a gap between opposing surfaces; a resilient cellular core; a bead of intumescent material; a flexible outer protective liner covering the cellular core and the intumescent bead; and, a remotely actuatable heat source disposed in the seal for activating the intumescent material responsive to a remotely generated signal, whereby the gap may be sealed by expansion of the intumescent material responsive to an alarm condition in a location remote from the gap. A system for sealing gaps in doorways, windows and the like comprises: a plurality of fire seals as described, affixed in gaps of the doorways, windows and the like; a plurality of detectors for sensing alarm conditions; a signal generator for activating the intumescent material responsive to alarm conditions sensed by any of the plurality of detectors; and, a controller for the signal generator, for selectively activating the intumescent material responsive to sequences in detection of alarm conditions by any of the plurality of detectors, whereby the gaps may be effectively sealed against penetration of smoke, noxious gases and the like prior to fire-like ambient conditions adjacent the gaps.
