evac tone generator

hey guys,
I run a small team and recently have found that paying someone to come out and do an evac training is hard as they want too much. so I will build the board myself.
I get most of what I need easily but am trying to figure out how to make the 2 distinct tones.

these are the 2 tones I am wanting to replicate.
http://arduino.cc/en/Tutorial/Tone shows a basic setup and am hoping I just have to input the right values. if anyone can help me out I will be so happy.
