What a weekend of sirens! Had such a blast at the Wisconsin meet, and got to run some pretty cool sirens. This one is mine, and the credit goes to “That Wisco Siren Guy” Tony. Thanks for the video! Tested Wail, Attack, Whoop, HiLo, Alert, and Air Horn (short considering air horn on the digital 864 is continuous)
