Oh sorry. Thanks for the article!

Thanks guys, map has been updated. My next project is to further categorize the sirens and add the Shearon-Harris system

(edit: working on Raleigh's flood sirens now)

Oh nice! Thanks!

For anyone who doesn't know, UNC Wilmington upgraded their siren system. I am looking into this now.
Edit: From the warning tones, they are probably ATI. They use whoop for the emergency tone, and westminister chimes for all clear.

Hi Jason,
Can you help me find the Harnett County GIS layer for the Harris Sirens? That would be greatly appreciated.
Thanks!

The mystery sirens with Modulators near Seymour Johnson Air Force Base are (possibly) ASC E Class EC4s.
If not they are unlikely going to be ATI HPSS-16s.

Select Shearon Harris under the layers then select SirenPoint. It will list all sirens in the EPZ. If you want to map them all and send them to me that would be super helpful!

Waste of money when you have a perfectly good Modulator right next to it
