Federal Signal Thunderbolt 1000 | 1 Min. Alert | Derby, Kansas | 7/15/24

At 12:00:05 Sedgwick County conducted a weekly test of their Outdoor Warning Sirens on Monday, July 15th, 2024, the test consisted of a 1 minute Alert. I’ve wanted to get a video of this for well over a year now, but it was never a priority so I eventually forgot about it. Then last month I heard the news about old sirens in Derby and Mulvane getting replaced so I knew I needed to get to this before it was too late. So today I made my way up there and got it done. It was loud, as usual for Thunderbolts, although not the loudest I’ve heard INFORMATION Date Recorded: 7/15/24 Main Shot: Canon PowerShot SX540HS Second Shot: iPhone 14 Pro Audio: Canon PowerShot SX540HS Weather Conditions: Mostly Sunny System: Sedgwick County Tests: Every Monday @ 12:00PM Weather Permitting: Yes Tests Cancel For: Rain, severe weather watch, temperatures below 32° (F), holiday Test Cycle: 1 minute Alert Time of Activation Today: 12:00:05 Siren Model: Federal Signal Thunderbolt 1000 Port: 5 Chopper Level: 3 RPM: 3.9 (Set to 4) Blower Type: A2 4M Replaced: N/A Siren Location: Behind Derby Fire Station 82 Distance from Siren: About 125ft Sirens Heard: FS Thunderbolt 1000 (Level 3) - 124ft Federal Signal 2T22B - 1.23 Miles Federal Signal 2001-130 - 1.37 Miles Check out my other videos: Recordings:    • All of My Siren Recordings   Ambiances:    • All of My Siren Ambiances   My Social Media: Instagram (I post siren pictures on here)   / sirens_of_the_south_and_mw   If you would like to use my videos, you do not have to ask, just give credit.
