here's a recording of last year's annual TMI siren test.

these are the sirens you hear...
at 00:09 it starts off with an ASC Cyclone. I think this is the one in my town about a mile or so away, since that's the only Cyclone within a few miles.
at 00:35, you can hear a distant Penetrator come in.
at 00:45, another Penetrator fades in (or it may be the last one that just spun a complete revolution). I think this is the Penetrator up the street a way.
at 02:05 the main feature (a dual-toned Penetrator 10) fires up. I was standing right underneath it and it about blew my eardrums in, hence the reason you hear my expletive after it fires off. if you listen close, you can clearly hear the motor starter solenoid kick in just as it winds up. this siren sounds for exactly three minutes.
I drove down the street about 1/4 mile or so, notice how it sounds slightly different from a distance. the dual-toned sound becomes more apparent, and it sounds like there may be multiple sirens. I can almost hear a little 2001 in there, but there aren't any 2001s within a few miles.
