Abstract: A fire escape system is described in which a latched escape door in a building is unlatched by withdrawal of a restraining pin from a latch mechanism, producing automatic opening of the door by any of various door-opening self actuating means described. In one embodiment, withdrawal of the restraining means results as a consequence of the transmission of a signal generated by a fire detection device, to an electric windlass system, which thereupon retractably winds a cable attached to the pin, withdrawing it from the latch mechanism.
