Fitting an anti-panic cylinder - SmartIntego Locking cylinder (Z4)

1. Inside thumb-turn
2. Recessed grip ring
3. Battery replacement key
4. Outside thumb-turn

The locking cam is always in a pre-defined position in the AP cylinder when disengaged. This prevents accidental blocking. Unlike other cylinder versions, the AP cylinder is installed the other way round (inserted into the lock from the inside to the outside).
