Free Mode
Free mode is used in a single-direction lane through which a patron enters or exits the
facility free of charge. This mode requires two vehicle detector loop inputs: loop A and
loop B. When a vehicle pulls onto the loop A, the gate arm raises. The gate arm lowers
after the vehicle clears loop B.
