Motorized Door Safety - Architectural Safety Solutions for Commercial Doors
June 16, 2026
Safe Buildings Begin with Safe Designs
Architects and specifiers trust Miller Edge to support safer door designs that align with today's building codes and safety standards. While motorized commercial and industrial doors improve efficiency, they also introduce potential entrapment hazards. Miller Edge sensing products help mitigate these risks—supporting both compliance and peace of mind.
Meet UL 325 Requirements with Confidence
Since August 2010, ANSI/UL 325 has required monitored entrapment protection devices for motorized commercial doors operating with momentary contact controls. Sensing edges and photo optics are two of the most effective solutions. Each offers fast response and easy integration into new or existing designs.
Entrapment Protection Devices
Sensing Edges
Touch-sensitive sensors that trigger motor controls to stop and/or reverse motion when activated by an obstruction.
Installed along the leading edge of the door, these devices create a responsive buffer between the moving door and obstructions in its path.
- Available in various profiles for aesthetic and functional needs
- Helps protect people, as well as vehicles and equipment
- Made in the USA for dependable quality
Photo Optics
Non-contact sensors that detect obstructions using infrared light beams.
Options include thru-beam and retro-reflective photo eyes, as well as light curtains for vertical protection. When a beam is broken, the sensor immediately signals the door to stop or reverse.
- Ideal for high-traffic or harsh environments
- Easy to integrate with most commercial operators
