Low Pitch FS 2001-DC Siren Audio Olympia Fields, IL 12/4/18
Ойын-сауық
Siren: FS 2001-DC, 2.2 RPM, 645 Hz
Town: Olympia Fields, IL
Location: Oakwood Terrace
Test Time: 1st Tuesday 10 AM every month
Cycle: 3 minutes of alert
Other notes: Here's the eastern 2001-DC in OF. This one is quite low pitched for some reason, but it provides some really nice echoes thanks to the country club next door. I wish they tested attack today like they did in 2017.
Again, at the end you can hear County Club Hills' 2001s doing attack.

Alert mean tornado watch
Sounds pretty good. I like the slightly lower pitch. That sound probably carries farther to.

It's way quieter though since the power is lower, so I don't think it would cover a greater area.
Not bad, batteires don't sound like they are too low or the pitch would have constantly dropped throughout the test. (if battery equiped. If so cycle them a few times they should be ok. If not then its a weak rectifier. (2001-TR on its way out.)
Could it be a motor issue or dying battery and that is alot of sirens for a country area is it that densely populated that many sirens are needed
