This is a 3 phase. You can see the siren shake from the torque if the motor.
0:45-0:47 is siren activation
That’s low mounted
why is there beeping

That beeping is a series of radio signals that activate the sirens.

Further, there was a card reader at a security gate for the ODOT garage that beeps continuously through the test.
