Thanks for the locations! They are really helpful. Have you ever heard them go off for a real emergency?

[CarolinaHurricane20]

Also, can you clarify on the level sense?

[CarolinaHurricane20]

I also saw some Modulators. Is that the odd one out, or is Raleigh slowly upgrading their system?

[CarolinaHurricane20]

Hey JasonC, how did you find the siren in Cary? I remember hearing it during a tornado warning, but no other times than that. Can you tell me more about the Fedelcode Model 5 and Darley Champion?
Thanks

Oh, yeah, sorry.

' Level sense' are at dams, they measure the water level going over the spillway & report it back to the control room. If it gets too high, the command to sound the sirens will go out to that one (except for the one I listed as 'level only') and all the ones downstream of that one.

Ah. thanks.

Thanks for the locations KB4MDZ. I have a map of the SHNPP sirens from the Harnett County GIS that I will add eventually, but I do appreciate the flood siren and NCSU locations. I'll add them in when I get the time.
