Memphis, Tennessee | Federal Signal Thunderbolt 1000T - Tornado Siren Test - July 20, 2022

Had this one in my sights for awhile now and finally recorded it. This siren has a 6M blower but it has a huge leak. I contacted OEM and they are now aware. No idea why it growled at the beginning. Thanks for watching. --------------------------------------------------------------------------------------------------------------------------- Location : 810 N Perkins Rd, Memphis, TN Siren : Thunderbolt 1000T Testing Time : Every sunny Wednesday at 3:30 --------------------------------------------------------------------------------------------------------------------------- © Copyright Sweet Tea Sirens 2022.
