Automatic Door Control Systems

Automatic door control systems are designed to open and close doors without the need for human intervention. These systems are commonly used in commercial, industrial, and public buildings, such as shopping malls, airports, hospitals, and offices, where convenience, accessibility, and hygiene are important.

The primary purpose of an automatic door system is to provide seamless and efficient entry and exit for users.

Sensors

Sensors detect the presence or approach of a person or object to trigger the opening of the door. Common types include:

Motion Sensor

Use infrared or microwave technology to detect movement.

Pressure Sensors

Embedded in mats to detect weight when a person steps on them.

Proximity Sensors

Use radio frequency or ultrasonic waves to detect objects near the door.

Control System

The control system is the central unit that processes signals from the sensors and sends commands to the door operator to open or close the door. It can be programmed for different opening speeds, durations, and sensitivity levels.

Door Operator

The door operator is the mechanism responsible for opening and closing the door. It typically includes an electric motor and an actuator that work together to move the door along a track or swing it open, depending on the door type.

The actuator is a key component that converts the electrical energy from the motor into mechanical motion, enabling the physical movement of the door. For sliding doors, the actuator moves the door horizontally along a track, while for swinging doors, it controls the rotational movement.

Safety Sensors

Safety sensors, such as infrared beams or laser scanners, are installed to detect obstructions in the door’s path. If an obstruction is detected, the door will stop or reverse to prevent injury or damage.

Security Control

Keycards or Keypads

Doors may require keycard swipes or keypad codes to grant access to authorized individuals, especially in secure areas like offices, warehouses, or data centers.

Biometric Authentication

High-security systems use fingerprint, facial recognition, or retina scanners to ensure only authorized personnel can enter.

Remote Access

Some systems are controlled remotely, allowing security personnel to unlock doors via mobile apps or control rooms.

Emergency Control

Panic Bars

Doors in public buildings or industrial settings often include panic bars that allow for quick exit during emergencies (e.g., fire alarms). Pushing the bar unlocks the door and opens it, regardless of security settings.

Fire Alarm Integration

Automatic doors can be programmed to open when a fire alarm is triggered, allowing for rapid evacuation. Fire doors can also be programmed to close to contain the spread of fire.

Power Failures

Many automatic doors have backup power systems to ensure continued operation during a power outage, opening automatically to provide exit access. In the event of system failure, doors often have a manual override system, enabling them to be opened by hand for emergency evacuation.
