Locking devices shall be protected against tampering from the landing side. The locking devices shall permit a door to be opened only if the platform floor is within two inches (51 mm) of the respective landing. The platform shall be permitted to move away from the landing under control of the normal operating device if the door is closed but not locked, provided that the device will cause the platform to stop if it moves more than two inches (51 mm) away from the landing before the door is locked.
