How Automatic Doors Work

Sensors and Mechanisms

Automatic doors operate using a combination of sensors and mechanical systems. The sensors, often infrared or motion detectors, pick up movement or presence near the door. Once the sensor detects someone approaching, it triggers the door to open.

Different types of sensors include:

Motion Sensors: These detect movement and are commonly used in shopping malls and airports.

Infrared Sensors: These use infrared light to detect heat and are often used in hospitals where more sensitive detection is required.

Capacitive Sensors: Rarely used but effective in detecting electrical fields, such as a human body approaching.

The mechanical systems then actuate the doors, either sliding them open or swinging them apart. The most commonly used mechanisms include electric motors coupled with a series of belts or hydraulic systems.

Role of Electrical Power

Electricity is the backbone of an automatic door system. The sensors and the mechanical systems both need electrical power to function. The sensors require a continuous power supply to keep scanning for movement or presence. Once they pick up a signal, the electric motors kick into gear, using more power to physically open or close the door.

Different power needs depending on the type of door:

Sliding Doors: Generally require a steady, but low, electrical current to keep the sensors active and a higher current to move the doors.

Swing Doors: Often need a more substantial amount of power to overcome the inertia of a stationary door.

Revolving Doors: These usually need a constant level of power to keep revolving at a steady pace and may require a burst of power if they have to open faster in emergencies.

Power Failure Scenarios

Emergency Power Sources

In the event of a power failure, automatic doors usually switch to emergency power sources. These sources include backup generators and battery packs. Backup generators kick in within seconds of a power outage, supplying the needed electrical power to the door’s system. Battery packs, on the other hand, offer a more limited timeframe, ranging from a few minutes to a few hours depending on the capacity.

Types of Emergency Power Sources:

Backup Generators: These are often diesel-powered and can supply power for an extended period.

Battery Packs: Usually integrated into the door’s control system and offer short-term power.

To know more about backup power systems, you can read the Wikipedia article on Uninterruptible Power Supply.

Manual Override Options

When electrical power fails, manual override options become crucial. Most automatic doors feature a manual override system, typically a switch or lever located near the door. Activating this system disengages the electric motor, allowing people to open or close the door manually.

Types of Manual Override Systems:

Mechanical Levers: Usually located on the side or top of the door frame.

Key Operated Switches: Require a specific key to switch the door to manual mode.

Safety Measures During Power Failure

Safety is a top priority during power outages. Signage often illuminates using phosphorescent materials, guiding people to emergency exits. Audio alarms may also trigger to alert people that they should use the door manually. In more advanced setups, mobile app notifications can inform building managers about the power failure and the status of the doors.

Safety Measures Include:

Phosphorescent Signage: To guide people in low-light conditions.
