Release devices control the closure of a rolling fire door, counter fire door, fire shutter or track door in an emergency situation. Release devices work in conjunction with the door or shutter to provide an effective fire and smoke control system by preventing spread beyond the area of origin. The device's basic function is to provide a time-delayed release of fire door or shutter upon receiving a signal from a smoke detector or central alarm station (or other remote switching device) or upon loss of power.
