Abnormal Law Warnings or Messages?

Takata wrote that the plane would have kicked into Abnormal Law due to AoA and speeds:
From 0211:40, she would not be anymore in Alternate law as all speeds and AoAs were invalidated => abnormal law: THS is frozen at +13 deg and autotrim become inactive (like the RTLU was at 0210:05, remember? we told you that it was its last valid airspeed before ADRs faults).
Sorry in advance if this has been asked and answered before, but:
  • If/when the plane kicked into Abnormal Law, what warning or message would have been visible or audible to the pilots?
  • Why was the transition to Alternate Law indicated in one of the ACARS messages, but no message about any other change in Law?
Thanks
