The Siren Board

Just found out that Shelby County, AL, a city close to me, is getting new T-128's or 135's cant tell the difference in the two visually, installed. Just think it was worth posting as i have never seen a T-128/135 in person before, in this case on the news. Preparing my video camera. Also, I searched keyword "tornado sirens" on the website (myfoxaol.com). Couldnt find a link.

P-50 T135's or T132's? And are they replacing a siren os any kind?

REALLY!!!I live on the Shelby/Jefferson county line. When and where so i can get my camera as well!!!!

Really?!? That is exciting.... where'd you here the news?

Whelens, Feds, and ASC that could make an interesting sound during tornado warnings 8)

Yeah! Be sure to get a recording! I don't know if I'll ever get to hear one of these great sirens in person, because Louisville is going with the 2001's, which sound sort of like fire truck sirens, and not CD sirens to me. If the new sirens near you are T-135 AC/DC's, I'd definitely like to hear recordings, because there aren't many videos of them on YouTube.

I just spoke to Don Greene who is the EMA director of Shelby county and he did confirm that the county was awarded 26 new sirens from a Fema grant and he the said the vendor will be American Signal but could not confirm the models. He said they are getting two types, he quoted " the louder of the two models will be placed in rural areas, and the other smaller siren in the municipalities areas" From that statement I assuming it will be both T-135 ac/dc and T-128's. He said the order has been placed and the sirens will be installed in May or June.

I saw the story on FOX6 News. Im really excited aswell, the reason I say
T135's/128's is it showed a video of one mounted on a pole. Thanks for the info Adam.

I just saw the story and it is a T-135 ac/dc they showed. That will be great if we can get that sucker here, i will have tons of "quality" videos once they get them!

Amen!

For picture of the T-135AC/DC, look at my Avatar. That was taken from a bucket truck just before a siren sound level test. By the way, we took far-field measurements that day - ideal testing conditions over flat ground - the T-135-AC/DC was putting out 85 dBC at one mile and about 73 dBC at two miles. The siren was mounted at 70 feet. At ground level we were measuring 116 dBC at 200 feet and essentially constant all the way in to the pole.

From a distance, you really won't be able to tell the difference between that model and a T-128. It is about a foot larger in diameter. However, the main difference is that the T-128 runs at 48 VDC and the T-135-Ac/DC runs at 72 VDC. If your area is installing them with battery back-up (which they should, since local electric power is one of the first things that goes out in a storm), then look at the battery box - does it hold 4 batteries (T-128) or 6 batteries (T-135).
