List of Rare Sirens

[ACCWA]

The three CTI models...is the SMO-15H this one?

I'm just inferring that it is an SMO15-H, I have no idea what it actually is.

Well that's actually not a bad name for it, I was just curious...so until we figure out what it actually is, we could call it that. Props!

I'm not sure if you could count Werden Electric's P-10s/P-15s. Perhaps another guy from Cincy can explain what the difference is between a Werden siren and an ACA Penetrator.

Really the only difference is the branding on the sirens. And remember Werden's model is called P-127 Portent. Within the past few years, they started making the B-115 Banshee. You could consider these sirens rare, as there isn't a huge number of them, but that's because Werden is only located in Cincinnati, and only communities in Southwest Ohio have been willing to purchase these sirens.

The T-Bolt 2000 in San Dimas was removed sometime around the end of 2009. There may still be one more behind Windsor hills elementary school judging by the pictures on http://www.wirechief.com/sirens/w4.htm since it appears to be the same setup as the one in San Dimas

It would be nice if someone would go take a look at it to see if it is a 2000 before it too is gone.

Right now, Hedberg sirens have become pretty rare. San Jose had 6 of them, and junked them. I only know about the Palo Alto one still standing.

A couple of quick notes...

1. The one you have listed as "550T" is actually "550-AT". The only one known to exist is in Calhan, Colorado.

2. The "Federal Signal Model 76" is a vehicle siren, not an air raid siren.

Also, some additions:

Federal Signal Model 3

Sterling (predecessor to Sentry):
M5
M10
N5
Y10
2V8
Little Giant

As far as port ratios for the Sterlings:
M and Little Giant - 16/16
N5 - single-rotor, 16-port
Y10 - 8/16
2V8 - 4/5

Note that the "M" sirens aren't as rare as the others, and Sirens For Cities (on YT) says that the 2V8 is "not rare, but sometimes difficult to find".

It's the same thing, the "A" just indicates that it has a 3-phase motor. Just like when you see 500-AT, or 1000AT. If they use a B, that means it is single-phase.

I would add some of the old ACA sirens seen in that brochure, like the Sentry 95, Screamer 105, and Cyclone 120. Also, I think the Chrysler prototypes definitely deserve a spot on the list (like the Gas Siren and "Big Bertha"). I would also add Darley and GCS sirens.

Ah. Thanks for the clarification. Since there is only one known 550 siren, I just assumed the "550-AT" was the only model they made.

Can you please identify some?
