ABSTRACT:
Electronic circuits capable of operating in a supervised capacity for controlling a mechanical release mechanism that releases a door. The circuits include a digital logic circuit for processing signals which are indicative of a condition in an outside environment and for providing a trigger that will actuate the mechanical release mechanism in response to a condition. The circuits further comprise a sensor input interface connected to the digital logic circuit for receiving a signal produced by a sensor in the environment that monitors the environment to determine the condition. Additional circuitry is provided interfaced with the digital logic circuit for controlling the motion of the door during occurrence of the condition in the environment. The electronic circuits and release mechanism described herein provide a full capability control system for rolling fire door and other emergency-type applications.
