The Siren Board

Thought this was interesting, hope it wasn't brought up before:

This has got to be very rare, so I'm wondering where it is...someone said something about a B-Series near Long Island, NY, but I'm not so sure...
(Note: this picture is not mine)

I am curious if it has a 4/5 port or a 5/6 port rotor in it.

Thanks for posting this! Something different!

Isn't the B-series single phase?

No the differential on all FS sirens is that a federal 1000A is 3ph and a 1000B is single phase. The A, B and C series thunderbolts are the generation of thunderbolt. Although I do believe and correct me if I am wrong but the B series... Okay I guess I shouldn't say no... And C series I actually think were all single phase... Right? I can't remember that part of it...

Yikes. Yikes yikes yikes. So much misinformation going on here. If you don't know, just stop.

That said, A, B, C series have nothing to do with phases. The phase is delineated by the letter after the number. 1000A is three phase, 1000B single phase.

Think of series as like how the B series 2001 was called 2001-SRNB.

And I kindly refer you to what I said... I said the A, B and C series are the generation of thunderbolts. And the 1000A is 3ph and the 1000B is single phase err... I said something like that. The only information on here that I am not sure of... I swear I have heard somewhere that all B series thunderbolts and most C series thunderbolts were single phase... But I don't know how true that is and to correct me if I was wrong on that. I hope I don't sound impolite or anything but... Yea.

Correct.

Rubbish

Yeah there one other B-Series 1003 that I know of and it is currently installed on top of a fire department over on the east coast somewhere. I know I've seen pictures of it on this forum somewhere. NY rings a bell for some reason.

My pleasure! I actually came across that by accident trying to look up images for a thunderbolt head.
Now, to clear up the confusion: from what I remember about naming thunderbolts, the correct way is:
(siren type)(phase)(dual toned/single toned)-series(series type). So, for example, a three phase A1 thunderbolt would look like this:
1000AT-SA1
That being said, when one sees 1000AT, it usually means that it's three phase. One would think so because I don't ever remember a 1000CT thunderbolt.
Hope this helps.
