An escape device is provided for lowering a person from a multi-storied building. The escape device has a reel assembly for storing a cable, and a support assembly for suspending a loose end of the cable over an escape path leading down the building. In a first embodiment, the reel assembly has a rotatable reel for winding and unwinding the cable, a base mountable onto the building and supporting the reel, and a braking mechanism for restricting rotation of the reel at a suitable speed for a person. The reel has a connector for retaining an end of the cable. The support assembly has a base mountable onto the building close to the escape path, a moveable arm connected to the base and supporting a pulley for receiving the cable from the reel, the arm being deployable and retractable between a ready position where the arm overlays the escape path and a standby position where the arm is drawn off the escape path, and a retraction mechanism for exerting a predetermined retraction force upon the arm to urge the arm toward the standby position, so that the arm moves from the standby position to the ready position only when the person exerts a force on the loose end of the cable. In a second embodiment, the reel assembly has a pair of coaxially aligned rotatable reels solid with one another for winding and unwinding respectively a pair of cables for lowering persons alternately. A pair of support assemblies are then provided for suspending loose ends of the cables over respective escape paths leading down the building on opposite sides of the reel assembly. The unwinding of one of said cables causes the winding of the other cable.
