Woodward's Siren Update

[dilloncarpenter]

Remember earlier this year when that tornado hit Woodward, knocked over one of their sirens, and knocked out power to the tower that sends the siren's signal to activate? If not, well that was most of the story lol. Basically, they were donated a bunch of new Sentry sirens, 3 16V1T-B's, and 16 7V8-B's, while retrofitting 4 of the old sirens. I'm assuming the ones they are retrofitting are the 10V's they already have. But the news stories don't tell this part...the 20 or so older sirens they had? Well, apparently, they are leaving those in place. This is according to their Facebook page. Here are a couple of pictures and comments from their EMA director that Ian found for me.


"One of three new mega-sirens that will be installed in Woodward this weekend, just arrived on the truck! Even though these three will cover the City, we are adding 16 additional sirens to our existing system that should over-saturate with coverage. Our goal is to get noise complaints instead of "I can't hear the sirens" complaints! Thanks again to Apache Oil and all of our oilfield partners and employees."



That map does not include the original system, by the way. Just to keep that in mind.

Basically, this town is going to be the Dumas of Oklahoma. Probably far more overkill than that, actually, or even Cushing or Moore. I'll make a coverage map just to show what it is.

Oh, here's a news article...

Interesting that they're using single toned 16Vs. (I'm assuming that the naming scheme is the same as the 10V series.)

I don't believe they offer a dual toned 16V unit, though I'm sure if a municipality explicitly specified it be so, it could be done since they use the same chopper assembly as the 8-port side of a 15/20V2T.

Nice, that will be an awesome system. I wish more towns would follow suit and use a combination of new sirens and the much more economical refurbished AC only models.

I can't link to it on my phone, but I believe there is a dual motor, dual tone Sentry siren somewhere on YouTube.

Yeah, it's a single phase 15V2T. Sentry went to dual motor designs on all the single phase sirens bigger than a 10V2T.

An idea came to mind about dual motor sirens being mentioned. If the dual motor sirens are single tone with one chopper for each motor,I'm thinking such sirens could be made dual tone by connecting each of the two motors to a variable frequency drive if the siren uses AC induction motors which VFD's are designed for & adjusting the drive's output frequency for a lower or higher tone output.
