System 4™ Door Controller (Standard)

Incorporating state-of-the-art motion control technology, the System 4 controller combines the flexibility and performance of AC Drive technology with the ease and precision of digital control.


The System 4 door controller is designed to operate with many different types of activators, depending on the application and operating environment.

Floor Induction Loop (Optional)

Activation loops embedded into the concrete on both sides of the doorway substantially reduce operator error in opening and closing doors. With no moving or exposed parts, floor induction loops are extremely reliable.

Motion Detectors (Optional)

Motion detectors operate on microwave technology. They detect pedestrian and vehicle motion in a prescribed area. The detector sends a signal to the controller to open the door.

Presence Sensors (Optional)

Presence sensors detect pedestrians and vehicles in the area of the detector. Motion is not necessary. The sensor signals the controller to open the door.

Radio Controls (Optional)

A radio control consists of a transmitter and a receiver. The vehicle operator activates the transmitter which sends a signal to the receiver. The receiver then signals the controller to open the door.

Push Button (Optional)

The push button is generally used with pedestrian traffic and is typically mounted on the wall near the door. Pedestrians push the button as they approach the door, which signals the door to open.

Pull Cords (Optional)

The pull cords are switches mounted on the ceiling. Pedestrians and vehicle operators pull the cord as they approach the door, signaling the controller to open the door. Vehicle operators generally have to slow down to pull the cord.

Multiple Activators (Optional)

The System 4 door controller permits many activators to be used in multiple combinations. For example, a door can be opened by forklifts through induction floor loops and by pedestrians through a push button, each with independent closing times to allow for pedestrians passing through the door.


Door Panel Options

2-ply or 3-ply Rilon,™ USDA compliant material, and screen material available.

Electrical Control Options

System 4 controller has programmable inputs and outputs to accommodate special control applications without additional electrical components.


In airlock applications, one controller with various activators permits doors to be interconnected so only one door is open at a time.
