While passing through Plankinton, South Dakota during a field campaign with the university, I noticed both sirens were being utilized for the tornado warning. I stopped to take a quick video. It was definitely loud, and they compliment each other well.

Siren Model: Whelen Vortex and Federal Signal 2001SRNB
Siren Signal: Steady/Alert
Siren Location: Plankinton, South Dakota in Aurora County
