That alarm means something is wrong. I assume your gear and flaps are in the correct position but check your descent rate. If you're descending at a rate greater than *1500 FPM(normal would be 900-1000 FPM, you will get a warning because it's unsafe. I don't think you can turn it off.

*not exact

Edit: Now that I think of it, what I said above would give you a "Sink Rate" warning.
