right-handed (RH) door is hinged on the right and swings inward. A left-
handed (LH) door is hinged on the left and swings inward. If either of these
doors swings outward, it becomes a right-hand reverse bevel (RHRB) door, or
a left-hand reverse bevel (LHRB) door respectively.

An optional feature that enables an authorized user (in an emergency) to
bypass all electronic locking features, and open the lock with a mechanical

whether the door is fully secure.
