The Siren Board

Wow, nice! It's not often when the community learns about a new siren. Well, "new" meaning not heard of before. Now we just have to find one in the wild, haha.

I noticed that on the brochure it also lists both the P-10 and Allertor as being available, which is interesting as I thought the P-10/15 sirens were introduced to replace the Allertor. The allertor on the page is also rated at 127 DB while the P-10 is rated at 125.

Indeed. My concerns about finding one are twofold:

1) The 2500 was obviously a shortlived siren. As was the 2000-R. And if it hadn't been for St. Louis, MO having so many 2000-Rs in their old system, its unlikely we'd have known about them as much as we do. I think there's only 3-4 known 2000-Rs in the wild (we know of) otherwise. I'm guessing it was either over-complicated, prone to failure, or expensive (or a combination thereof) as it was obviously meant to fill in the 2000-16 in the lineup (and we know that siren lasted for quite a while).

2) Its a siren head that seems like it could blend in and be mistaken for something else. Its possible if any are out there. Heck its possible we've seen one and dismissed it as a vent or something.

Oh wow, that pamplet is amazing. Not only detailing a totally unheard of siren, but also explicitly mentioning the existence of a mobile siren too. Wasn't there another thread recently discussing the existence of mobile warning sirens like that? What a cool find in so many different ways, thank you for sharing!

Didn't the Alertronic directional sirens come out before the Whelen 3000s? I read somewhere that they had copied ACA's design.

the thing about design copying I think you might mean soundmaster because ACA put them out over the lawsuit for copying the banshee design. I have never heard about design copying of the allertronics. they could have just taken insperation or just ripped off the designs unless the allertronics came first.

Oops, I was wrong. It was ACA that copied Whelen's design. The 3016 was introduced around 1982 while the Alertronic 6000R came out a year later in 1983.

well then could be aca ripped off whelen.

uhhhh
i doubt it. while they may have been following the trend of electronic sirens the 6000R doesnt share much with the 3000 series. aside from being a huge thing on a pole, I dont think it had the ability to index it's rotator, and they used collector rings too IIRC

The 6000R's design is quite similar to the 3016 in my opinion. Both have speaker drivers in a back panel connecting to a triangular-rectangle shaped horn via several cone shaped tubes.

If I'm not mistaken, in the patent of the Alertronic, Biersach literally cited the WS-3000 patent and criticized it right within patent.
