The Stanley Swing-Guard Swing Door Safety System is designed to detect moving or stationary people and objects in the swing path of the door, via its sensor, providing reliability from potential harm. It can sense any people or objects obstructing the swing pathway. The technology also recognizes and distinguishes interferences from environmental factors such as rain, snow, and debris via a built-in Rain Mode and Snow Mode that would normally affect other sensors. The system is placed on the upper corner of the door leaf on the hinge side. When the door opens, it maintains complete coverage of the area around the door and automatically adjusts to the approach and swing areas. When the door closes, the safety system reverses the process. As a result, the areas surrounding the door are kept constantly safe.
