I don’t think I have seen anyone else ask, and I’ve been searching for an answer.

I believe they recorded it around 1992 when the 4100+ was introduced. They also recorded a similar message for the 2001/2120 as an optional digital upgrade from the tape decks IIRC.

4100 voice evacuation was released in 1989.
