The 4900 series has a suitable solution to any door system that requires free operation from the interior at all times but access from the exterior only at certain times. A reverse turn of the key while bolt is held retracted retains the bolt, to allow two-way traffic for applications which require free entrance at certain times and exit-only at other times.
