Federal Signal Thunderbolt 1003 Siren Test - 1min Alert - Niles, IL 7/4/23

My first Thunderbolt! This was fun.

This test was stressful. Parking was basically nonexistent since there was a parade happening on the ENTIRE BLOCK, so my mom had to go around the block while me and my brother ran to the siren to set up. Niles tested early - literally 1 second after I started recording, the siren fired up, so editing the video was a little challenge. My brother screamed during the windup, so I had to extract him from the audio using lalal.ai, which worked blissfully. After the test, I had to take photos in a rush. I was tight on time since we needed to get out of there ASAP because if not, we wouldn't be able to get out since the parade floats would go around the block and prevent us from getting out for the rest of the day. Super fun test overall, and that's what I was aiming for since this is, unfortunately, the last siren test I'm going to for a long while.

As for the siren itself, it was as loud as a Thunderbolt should be, and worked as well as any Thunderbolt should work.

Enjoy this 4K video!
