3 waves if I remember right, also the gremlin healer and bombers made it kinda difficult. Forgot to take a screen shot after winning it though.
So I take back what I said about these rooms being easy. I'll think twice before entering a T3 danger room again.
Update # 2
Found another danger room in T2
