Non-lockable shield EN3100 - allows free access at any time.

Anti-vandalism: If an abnormal force is applied or if a rough crank force is applied (> 45 Nm), the handle will slip. This feature prevents the door from being opened even if the outer shield looks no longer functional.

Restore the outer shield: return the handle to the correct position to return to its normal position, after unlocking it is possible to open the door by default.
