Automatic Doors & Garage Doors

How do automatic sliding doors know when to open?

They use sensors above the door that detect movement or presence in the approach zone. Radar (motion) sensors react to a person moving towards the door, while infrared presence sensors detect anyone standing in the opening so the leaf does not close on them. Some entrances add a push button or access control reader for touchless or restricted operation.

Sensors need periodic cleaning and calibration to stay accurate, which is part of routine maintenance on our automatic sliding glass doors.
