The Siren Board

Today was the annual test of the system around the Susquehanna Steam Electric Station near Berwick, PA. This T-121 is one of the outermost sirens, located in Mifflinville, PA at the fire station.

Susquehanna Nuclear tests on the 3rd Thursday of August at 11 AM, and I believe this particular siren also sounds for fire calls.

Enjoy!

This is probably a noob question, but are those tones before and after similar to the EAS DTMF start/stop message tones?

These are FSK tones which are very similar to those used for the EAS SAME headers, so yes.

Gotcha. Thanks.
