Siren: ACA P-15 3 Phase, 3.15 RPM, 473 Hz
Town: Downers Grove, IL
Location: O'Brien Park
Test Time: 1st Tuesday 10 AM every month
Cycle: 1 minute of alert
Other notes: Since I'm in Pennsylvania currently with a broken car, there'll be no 1st Tuesday for December, but I still have other siren videos to share. For November, I decided to start going through Downers Grove's system. They have 1 STH-10 and 6 Penetrators. At least one Penetrator is dual tone so there could be more; so far we have 2 single tone and 1 dual tone.
At the end you can hear 2001s to the south, most likely from Bolingbrook.
