I don't have the tones, but here's some software that a lot of people use to decode them:
ComTekk Two-Tone Decoder
DMPD uses tones (but not two-tone fire tones) for holding traffic. There are some other tones that DMPD/DMFD use for super special emergencies like all available cars needed at XXXX location for officer assistance, man down, or tones to evacuate firefighters out of unstable structures before the building collapses. Those "special" tones will make you crap your pants when you hear them.
