FAQ
Frequently Asked Questions
It is a two-word compound noun, commonly written as two separate words. Hyphenation ('automatic-door') is rare and not standard.
Typically, no. 'Automatic door' most commonly refers to sliding or swing doors activated by sensors. Revolving doors are usually manually pushed, though power-assisted versions exist. These are often called 'powered revolving doors' rather than automatic doors.
An 'electric door' has a motor but may require a button or switch. An 'automatic door' implies a trigger (like a sensor) that removes the need for any manual action to start the opening cycle.
Modern automatic doors are designed with multiple safety features like pressure sensors, infrared beams, and safety edges to reverse direction if an obstacle is detected. They must comply with strict safety regulations (e.g., EN 16005 in Europe).
