Sentry 3V8 Siren Test Swan Creek, IL 7/26/22

Siren: Sentry 3V8 Single Phase, 473 Hz Town: Swan Creek, IL (Warren County) Location: Fire Department Test Time: Every Tuesday 10 AM Cycle: 40 seconds of alert Months after discovering Warren County does weekly Tuesday tests, I finally made it out here for such said test. This Sentry is located at the fire department in Swan Creek and was freshly refurbished. Supposedly this came from Roseville just a few miles north of here, however that town had a Darley Champion before they got their new Sentry.
