The Sentries are a mixture of age. The one near the apartment building and near the equestrian center appear to be older 90s models, so I doubt they'll be replaced if they're still up. Clinton Massie appears to be a newer, mid 2000s unit. As far as the fate of the 2001, I'm going to send some texts ...

The firefighter in Blanchester who maintains their city sirens informed us that their Beams came from Wilmington and are single phase. That also makes sense since the one I recorded in Clarksville was also single phase.

Also, the Whelen system replaced Thunderbeams in the early 2000s. The thunderbeams went to Clarksville and Blanchester where they are still running today.

Wow! I've tried to record this multiple times with no luck in them testing. That's a shame to see a smaller siren replace that, but it will be a cool addition to their system. However, The OAs are impressive for their size; I've recorded the one at the college. Keep us informed on the fate of this b...

http://www.fox19.com/story/37561997/officials-investigating-dearborn-county-tornado-siren-delay Welp,Dearborn County had a major failure this morning. Most of their sirens failed to activate during the tornado warning and it has made the news. This doesn't surprise me as I have seen so many of their...

Boone County didn't test due to Ice accumulation on the sirens. Apparently The OEM called dispatch after I did and told them not to test. Makes sense considering they've had issues before with their 2001 rotators locking up in the ice.

Central Pkwy/Linn T128 accident Well today at about 10:30 I got a text from my Uncle who works at Engine Co 29, He told me a car had crashed into the tornado siren at Central Parkway and Linn Street. He asked me if I knew who to contact and I told him that I did and would leave a message. He said th...

That's pretty cool. They've sold Federal, ACA, and now they sell Sentry products.

That is not a real siren map.

Ok, I thought the Calhoun Hall T-128 started up a little late in the minute, and it’s test only lasted about 2 minutes. I could hear at least one other T-128 for a couple minutes after this one stopped. That explains everything. Interestingly, I could clearly hear some 2001s from Northern Kentucky ...
