I think that "strange sounding 2001" is just a 2001 with the attack cycle set to a different timing than we're used to.

Are you talking about the signal that starts at about 1:24? That's the "Fire" signal the FSC 2001 is capable of and is called "Fast Wail".

Signal / Frequency Range / Sweep Rate
STEADY / 790Hz / N.A.
WAIL / 470Hz - 790Hz / 10 sec.
FAST WAIL / 600 - 790Hz / 3.6 sec.

Here's a video of Derek testing out a 2001-SRNB. At about 1:56 he tests the Fire Signal.

It sounds a little off for Fast Wail, but that's what it could be doing. Notice how it alternates between the wail and a steady Alert signal. That's what's so weird about it.

I think it may have been two different sirens he recorded. During the video, he changes location frequently so it is most likely a different siren that was sounding Fast Wail.

That video link I sent you earlier, with Derek testing a 2001-SRNB, that town uses "Fast Wail" for storm warnings with that siren.

It is interesting though how cities will use certain signals.

Anybody notice how the pitch of the 2001 changes at 1:35 when the power goes out? Battery backup in action.

I didn't notice anything, but this video certainly makes me love the 2001 series siren. It really sounds at "home" in this video, hehe.

I liked the thunderbolt 1000. Is there any visible difference between the various 2001 models? (i.e. DC, SRN, SRN-B, 130, easy to tell the difference between a new 2001 and a roundback one! )

2001-DC simply refers to the type of motor in the siren. A DC motor is required for battery back-up, so a 2001-DC will have battery back-up (usually). A 2001-AC uses an AC motor and will be hooked into the electrical line without battery back-up.

The 2001 SRN has gone through multiple iterations. Each one uses the same rotator as the Thunderbolt.

1) Roundback with narrow motor cover
2) Square back with narrow motor cover
3) Square back with wide motor cover.

The 2001 SRNB debuted a new, much smaller rotator (looks like a cube), as well as, in late models, a gigantic FS logo on the wide motor cover that looks a lot like the one that would end up on the 2001-130.

The 2001-130 is very obviously different from the 2001 SRNB in that the square back is now an elongated rectangular back.

Hope that helps.

Early versions of the 2001 featured a round-back design with a Thunderbolt 1000 rotator mechanism:

The 2001-AC/2001-DC version featured a squared head with a Thunderbolt 1000 rotator mechanism:



The 2001-SRNA/2001-SRNB featured a cubed rotator mechanism:



The 2001-130 features a larger (rectangular head) compared to the square head of previous generations. It features the same cubed rotator mechanism:
