How long does the automatic boom arm take to lower at the parking lot?

The automatic arm in the parking lot will drop 20 seconds after passing through. However, it's generally感应-driven; the arm will only drop after the car has passed.

The parking barrier arm uses inductive loops before and after the arm to detect if a vehicle has passed the barrier position. After detection, there is a brief delay before the arm lowers. More advanced barrier arms also feature anti-crushing mechanisms, which may be used if the vehicle is smaller. Need I say more about those manually controlled barrier arms?
