#1: CADI GC is not for 330A, the old CADI is compatible with 330A old versions
there's is not menu on the display to lockout the floor, unless you want to add a CODE (code require to access the floor)
or depending on your job configuration maybe X3 connector on the COP (push button boards) could help you to lock out the floor
you want to lockout the floor just by car?, just by hall? or both ?
