FAULTFINDING TABLE
CAUTION: In the event of a mechanical failure on one of the door lock devices integrated with the lock, the control unit safety logic makes the lock itself stay open. In the unlikely event that the doors stay shut and locked, it is however still possible to open the lock manually: using the key from outside or raising the knob from inside.
N.B.: cutting off the supply does not "unlock" locked doors!! Locked doors will only open when the supply is received again.
