Before he retired My grandpa worked for Mobilcomm, the guys who work on Motorola police radios and Clermont county's sirens. So he knows all about weather radios, EMS radios and a fair amount about storm sirens.
I know sirens can get hacked and have false alarms (Clermont county had several problems with that on the new DTMF system so they installed a switch between controller and transmitter to stop accidental activation).
The most important thing he taught me is that systems are supposed to work together, its like how your car has airbags and seat belts. In Hamilton county the EMA has an app (You bet I have it) and 190 sirens (as well as other sirens not officially on the system that sound for heavy weather such as the ASC T112 at Kenwood country club.) They work well together, sirens go off in alert, telling me to check my phone, and the phone elaborates on the emergency.
Speaking of, isn't the whole purpose of the alert signal to check for a civil defense alert?
Getting back to the power plant, Based off of what happened with the Zimmer plant's 1212 prototypes, there's more than likely some bonafide buyers eyeing the sirens, given they're low hour newer models, rather than a 60 year old thunderbolt. I know a few enthusiasts who would hide a body for a siren.
Yes people will complain they always do, I finally got my counterbalance forklift certification after asking about it since June. But listen to complaints from people who know what they're talking about. Some people complain that they have to wear a mask after all and I sure do like ignoring them.
