An electronic door security system employs an input console having three readers for enhanced security. A microprocessor processes inputs applied at each of the readers to selectively permit access through a secured door. Application of an input to any of the readers transforms the controller from a sleep mode to an active mode.

Multiple access electronic lock system

A exit bar for securing a door has a housing adapted for mounting to a door. A push pad for receiving a push force is mounted to the housing. A latch extends from the housing to releasably latch the door to which the exit bar is mounted. A link system links the push pad to the latch so that a push force exerted on the push pad releases the latch. An electromagnetic disposed in the housing causes an armature to engage the link system to retract the latch. The exit bar further dogs the latch in the unlatched position as long as the power control system for the electromagnet receives an operate signal and for a preestablished delay time after the operate signal has been removed.

A sliding door sensor employs two arrays of IR emitters which are pulsed to provide an approach detection zone and a threshold detection zone. Radiation reflected from the detection zones is converted to signals which are processed in microprocessors. The sensor periodically automatically adjusts for changes in background. Both presence and motion detection is provided. The sensor also detects dark objects.

Sliding door sensor

A sensor system for an automatic sliding door employs multiple sensor modules. Each of the sensor modules includes both a presence sensor and a motion sensor. In addition, each of the sensor units includes switches for adjusting the size of the presence zone, for selecting either a continuous or a triggered scan mode and for selecting an operating phase to prevent interference. The sensor units are generally mounted above the threshold of the doorway and their opeations are synchronized to provide both a traffic sensor and a safety sensor for a sliding door system.

Door sensor system

A manual power assist control employs a magnetic encoder which is mounted to a shaft of the door operator. The encoder generates pulse trains which are indicative of an attempt to open the door in a given direction. The pulses are processed to generate a signal for opening the doors in the event a manual attempt to open the doors is detected.

Automatic assist for swing-door operator

An operator for swing-door employs an electronic control unit for controlling the operation of a motor. The motor is bi-directionally driven at various speeds for opening, closing, braking and maintaining a given position of an associated swing-door. The motor drive shaft is mechanically connected via a timing belt/pulley system with an operator shaft for transmitting torque to a linkage assembly. The linkage assembly is configured to provide a high mechanical advantage at the fully opened and fully closed positions of the associated swing-door.

Swing-door operator system

An automatic control system for controlling the operation of a sliding door system employs an electric motor for driving the sliding door system. An encoder is mounted to the shaft of the motor for generating signals which are decoded to detect the operational position of the sliding door system. A clock paced sequential logic circuit produces speed and directions signals in accordance with the detected operational position to control the speed and direction of the electric motor. Means are provided for recording the last stop position and slowing the sliding door system prior to reaching the last stop position. Safety means are provided to de-energize the motor in the event of malfunction of the motor speed control. The system also includes a reduced opening stop feature and a means for automatically establishing a sliding door reference position.
