Cincinnati Metropolitan Area Sirens

[carexpertandy]

I’ve been watching all about the Ohio River flooding on the local news this afternoon. Channel 9 showed drone shots of Coney Island and the area around it. The intersection of Kellogg & Sutton is pretty bad, and the 2001 there has water surrounding the bottom of the pole. Can sirens potentially get electrical damage from flooding?

If it reaches the siren yes, my main concern would be the controller since it is lower on the pole.

Lol if water reaches the siren head then I think we'd have bigger problems to worry about than damage to the siren...

I drove by the Federal Signal 508 on University Bvld in Hamilton, OH and noticed that there was a cherry picker next to the siren. They had the control box open and were fixing something. It seems to me that this siren failed the past two tests as I have not seen it change positions since January. I almost wonder if something was wrong with the radio?

Saw today that, according to the Clermont EMA, their sirens sounded 3 different times due to a transmitter malfunction... Wonder what would cause that. They have a two-tone activation and an ASC FSK activation, right? I don't actually know how exactly their system works...

They have a Compulert encoder and a tone encoder. That being said, I'm not entirely sure how a transmitter would cause the sirens to be activated three times, unless it's severely delayed on sending transmissions out. It seems like they've been experiencing transmitter issues a lot recently. Perhaps it's time to look into replacing some radio apparatus?

Older compulerts had issues with command stacking. Its a very real possibility that is what could of happened here. I know all of werdens stuff is what has been installed in clermont. However i remember it like yesterday when the stuff was installed quite a few years ago as a fyi. ~hannah

I was watching a short film called Day of the Killer Tornadoes (which is about the 1974 tornado outbreak), but there's a short segment where they walk through the Sayler Park tornado. They have a sequence where they activate the sirens with a phone, but there's also an old map of the Hamilton County system... this film was made in 1978, so the map is from around then. Pretty cool!

It’s amazing how few sirens were in the county system back then. I would think that not long after this, there was probably a push for jurisdictions to install more sirens, and probably even add volunteer fire department sirens to the system.

Didn't see this posted here. Clermont did a special test yesterday to try and solve the issue from the first Wednesday test, they ended up doing 2 alerts again.
