Apparently, it might not just be that siren, and FCEM&HS suspects foul play may be involved, per the article I'm sharing here:

Also, a screenshot here identifies where there's been at least one suspected unauthorized activation... You're near there, right WPS4004Man?
I live down in the Meadow Grove Estates area of Grove City, and thankfully I don't believe that we've had any down here. I remember one night a couple years ago where I could hear one off in the distance accidentally set off in high-low, but that's about it for any accidental and/or abnormal activations I can remember here. I also thought that the activations during the 5/18 tornado warning were quite odd as well (those "growls" instead of three minute activations), but it sounded like for the 6/10 warning on my side of the county, things were back to normal.
