On page 4, the siren name that is used in the DLS.xml is the same for two different sirens. The name for [siren_2.wav] and [sirens_firetruck_quick_01.wav] is listed as (fast_9mvv0vf), even though the tones are different. The result in game is that the [siren_2.wav] sound plays and the [sirens_firetruck_quick_01.wav] can't be accessed at all in DLS.
