Stall Warnings

Acoording to the Air Caraïbe ASR, the stall warnings are triggered as soon as the AoA exceeds a threshold which is a function of:
-the aerodynamic configuration (slats/flaps)
-the airspeed (kts) or mach point
-the control law (normal, alternate, direct)
I wonder if this AoA/speed threshold computation is the same as alpha floor & alpha max computations (excepted that the AoA law/alpha prot. will no longer take over to control/protect the plane since it is no longer active, but will only sound a warning as soon as the AoA threshold is exceeded). Does anyone know how these alpha threshold are computed ? (where can we find the AoA threshold tables ?)
