Nice video there is a video of a close 2001 being activated in my city of Minneapolis MN but you could hear distant 4/5 Port Thunderbolt 1000Ts going first
The Kalamazoo Tornado sirens are triggered remotely individually by a DTMF sequence transmitted over a radio. It takes a bit of time to transmit all the DTMF sequences.
Those 2001- srn's are no joke! I live very close to one.

Sounds like it was a fun night for the southern part of Michigan!
