Obstacle detection.
Concerns over children playing on your driveway are removed by the use of clever safety technology. For instance, an automatic safety cut-out stops the door if it encounters an obstacle and reverses a short distance. Modern operators don’t just “push” the door they open and close it – they monitor force levels through built‑in safety circuits many times per second. Any unexpected increase in force caused by even a small amount of resistance is treated as a potential obstruction.
