The product has a thumb-turn on the interior to switch between
- Auto-lock (Thumb-turn oriented vertically - locks after each entry) &
- (2) Passage mode (Thumb turn oriented horizontally - remains un-locked)
This thumb turn functionality can be electronically disabled, such that the door always auto locks with the thumb-turn in vertical or horizontal position. Refer the installation guide here, this is ideal for public restrooms, so user cannot
turn the turn piece to passage mode & allow unauthorized access.
