A full door protection unit, also known as a door scan, is a safety device that eliminates the manual retracting door edge. As of May 25, 2021, the State of Illinois has adopted the A17.1.2019 code which requires enhanced protection in most instances. This enhanced safeguard is commonly referred to as 3D door protection.
Door scans generally use infrared light beams to continuously scan and detect obstructions within the elevator door’s path. If any of the beams are broken, it will instantly open the elevator door without touching or harming passengers. A 3D unit is designed to detect people or objects as they approach the door. Similar to automatic doors at a grocery store, the elevator door reopens before the passenger gets to the entrance.
A 3D door scan not only protects passengers but also helps prevent damage to the elevator’s doors. It is ideal for buildings with slow moving people, delivery people, hospitals and where heavy equipment is used. Even in residential settings, it is a great feature to have.
Benefits include
- Increased safety
- Decrease in damage to elevator doors from various objects and equipment
