There is only one bell, but you can change the volume and ring rate. See pages 43 and 44 in the manual ....

I have an HO Genesis BNSF GP50 with Tsunami DCC and Sound, are there multiple bell sounds? It comes with the default bell which I would like to change to an E-Bell, since most BNSF yard switchers had E-Bells. If so, what CV would this be?
