Type: Federal Signal Thunderbolt 1000
Signal: Alert
Location: 14400 49th Street N, Clearwater, Pinellas County, FL (Pinellas County Jail)

The famed Pinellas County Jail 1000. This was cool to see and hear, and it was quite loud even as far away as I was. At the very beginning of the video there appears to be some sort of ASC electronic siren sounding one blast of air horn. I have yet to locate it. Enjoy!

The Pinellas County Jail escape siren is tested every Friday at noon ET.
