Federal Signal Modulator 1004 Siren Test (Attack) Brentwood, TN

This siren is located at Granny White Park in Brentwood. Williamson county sirens tests first Saturday at 1PM CT. Finally, after 4-5 years, I finally filmed the blue modulator in Brentwood, after hearing it in the distance on its MCP back in 2020, I wanted to go to it since. It no longer has its MCP, since that was replaced in 2021. Tennessee Siren Map: https://tinyurl.com/tnsirenmap Kentucky Siren Map: https://tinyurl.com/kysirenmap
