I think thats the binary code thats sent by the EM director that tells the rotator motor to rotate 90 degrees and sound the tornado warning line.

You gotta admit that 90 degree turning is pretty awesome.
If at first you don't succeed, destroy all evidence indicating that you tried.

The noise is the DTMF tones.

Weird. Could it be the encoder/decoder?

DTMF is the "language" that the siren speaks. Each siren has an "address." So in a sense, yes it's the box telling the siren to rotate 90 degrees.
