Other notes: For those of you who read the description of my Frankfort 'bolt video, you would've seen that Clermont County had an FSK systemwide failure on the first Wednesday of March, and after that we were fully expecting them to re-test the following Wednesday. Sure enough, a post on the county's Facebook page confirmed that they would indeed be re-testing, so we knew we had to come back down there and record something. We ended up going to this P-15 on Locust Corner Road with Jeremy and Dominic since it was nice and sunny out and this was one of the sirens in Clermont I wanted to film on a sunny day. This wasn't the first time I attempted to film this siren though. Both Connor and I first tried this back in December 2020 along with a few other enthusiasts, but once again, the county had a systemwide failure due to radio troubles. Connor then filmed this by himself in March 2022 while I was still in college, but he wasn't fully satisfied with his video from then and I still wanted to hear it myself. There is a large generator right next to this siren, and we believe the siren is hooked up to the generator to provide backup power in the event of the main power failing. What's interesting though is from what we've seen, the siren runs on 480 volts (quick windup and higher pitch) when on the main power, but when it's running on the generator it doesn't get quite as much power (slower windup and lower pitch). In fact, when we first got here the generator was running, but about 15-20 seconds before the test, it shut off, thus allowing us to get the full potential of this thing. And hoo my goodness, it was SO loud! This is one of the loudest Penetrators I've ever heard! It beats the other Penetrators in Clermont I've been to, and I'd say it's right up there with how loud the one in Montello was from my memory, as well as Batavia's Allertor. It still wasn't quite as loud as the Allertor in Grand Ledge, although it probably isn't too far off. Not only was it super loud, it was also so UNGODLY shrill and distorted, possibly even more so than the other Penetrators I've heard. It was practically just earrape white noise when the horn faced us. Anyways, this was an awesome test and I'm so glad I finally got to hear this thing in person. Enjoy!
