Federal Signal Thunderbolt 1003 Siren Test - Bement, IL

Featuring Cooper, Central Illinois Sirens, TheMainDrew, Iso, Blue Bolt, Zion, MOX, Illinoisirens07, and nascarsimracing1. The third of 4 siren tests from Illinois during EAS Expo 2024, and the best one by far.
This video features a Federal Signal Thunderbolt 1003 located in Bement, IL, going off for an alert test for 3 minutes and 1 minute of undulating hi-lo (very rare) and then it wails down. By far the best siren test I've ever been to during the expo, this siren alone got me really interested in them so stay tuned for more siren tests on this channel!
Recorded on August 6, 2024 in Illinois.
