Abstract: A resettable fail-safe fire door release mechanism which allows normal powered operation of a fire door is disclosed. A solenoid having a first open state in the absence of an applied electric current and a second closed state in the presence of an applied electric current is incorporated into the motor-operator unit of an overhead door. Brake actuator utilizes the spring force of a normally disengaged brake to keep the brake actuator in a first position. The plunger of the solenoid acts through the brake actuator in opposition to the spring so that energizing the solenoid overcomes the force of the spring, moving the brake actuator, and engaging the brake; deenergizing the solenoid causes the spring to again disengage the brake. A normally closed switch having a mechanical actuator is wired in series with the solenoid. The melting of a fusible link releases a spring loaded plunger which depresses the actuator opening the switch. A cable having one end connected to the actuator of the switch and the other end external to the case of the motor-operator allows manual opening of the switch and hence closing of the door.

Abstract: A fusible link dropout or disconnect device for a motor-operated fire door which is advantageously located on the motor shaft and is an integral part of the chain drive by which the motor operator powers the fire door support shaft through rotation to correspondingly urge the fire door through opening and closing movements. The chain drive, consisting of the usual endless loop of chain entrained about spaced-apart sprockets, functions effectively while permitting a degree of lateral shifting movement of the dropout which is utilized as the disconnecting movement thereof in the event of a fire.

Abstract: A power-off door closing device of fire proof rolling door in which the rolling door slides down to close by its own weight under abnormal power-off condition by brake-releasing action or by brake-applied action of a braking pin actuated by a energized solenoid, through successive movement of the first end of a sliding lever of a solenoid with a bent arm, a clamp member and a brake actuating rod. This device can be easily changed into non-failsafe door closing fire proof type with original configurations wherein the solenoid is reverse located so that the brake-released action caused by an energized solenoid or the brake-applied action under abnormal power-off condition applies. A reserved power supply temporarily energizes the solenoid to maintain a temporary brake-releasing under abnormal power-off condition, to enable the rolling door sliding down to close by its own weight.

Abstract: A parking area control and management system employs a card reader, which reads identification information from a card commonly carried by a person, such as a driver's license or credit card or other identity card carried by a user that is issued by an entity other than a parking area management entity. A record is made of the identification information upon entrance of a vehicle into the parking area. The person may subsequently leave the parking area on foot and regain entry to the parking area by presenting the same card. Later, the same card is used to exit the parking area, via the vehicle, and to validate that the same person is leaving with the vehicle. The parking area control and management system also includes sensors, such as loop detectors and electric eyes, to determine if a second vehicle or a pedestrian follows behind a vehicle entering into, or exiting from, the parking area. The parking area control and management system can be used to manage existing loop detectors and electric eyes, that normally control door and gate safety access systems, and to integrate those devices into an alarm system, such that an alert is issued whenever an abnormal or unauthorized event occurs during operations.

Abstract: A non-contact sensor system controls movement of a door moving in a first direction. The system includes a rigid mounting bracket attached to a leading edge of the door, a transmitter extending a distance beyond a leading edge of the door at a first door end for transmitting a signal toward a second door end. The transmitter is attached to the rigid mounting bracket by a first moveable member configured to engage a surface when the door closes and moving to a retracted position. The sensor system further includes a receiver extending a distance beyond the leading edge of the door at the second door end in alignment with the transmitter for detecting the signal and for generating an output signal. The receiver is attached to the rigid mounting bracket by a second moveable member configured to engage the surface when the door closes and moving to the retracted position.

Abstract: A smoke release and ventilation system comprises a frame housing upper and lower members each slidable in the frame between a normally closed position and an open position, the upper member being retained in its upper position by retaining element, for example an electromagnetic, the upper member being heavier than the lower member whereby, on release of the retaining, the upper member falls under gravity to its open position, and, consequential upon said fall of the upper member and the kinetic energy thereof, the lower member is raised to its open position, thereby providing gaps above and below the members and through which smoke can escape.
