The Next Systems ACNSEM3L garage door control panel controls two traffic lights with two or three lights each. It alternates traffic in two directions, keeping both lights red for a period before each change to clear the shared lane.

Operation can be based on timed intervals or sensor signals. Relay outputs control the red, amber or green lights, while LED indicators show the current colour of each traffic light in real time.
