The Siren Board

If it goes through with all 508's it will sound like Nashville.

Holy overlap batman! Hard to believe they would install that many, but the point about high winds out there is a good one.

Anything omnidirectional like:
ASC T-121
FS Eclipse8
Sentry 20V2T, 16V1T or 40V2T

If its omnidirectional you'll have to add a lot more sirens.

The best siren system design (though not necessarily cheapest) will include both rotating and omnidirectional sirens. Omnidirectional sirens have the benefit of acoustic summation between siren sites, so they can be used in town centers where it's important to deliver consistently high sound levels without creating 'hot spots' where the system seems "too loud". They should also be installed in parks, sports complexes, and other areas where people are most likely to be outside during a storm, for spot coverage. Rotating sirens can then be installed to fill in the rest of the area. Because the beam rotates, the sound level from a rotating siren is not as consistently high as with an omnidirectional siren.

I am glad people are starting to really understand that voice siren systems don't work well over a wide area, because of delayed multiple arrivals ruining the intelligibility of the voice message. Voice sirens can be installed in areas like parks to provide audible messages originating from a single location, but they should not be installed such that their coverage patterns overlap. A single larger siren is better for covering a large area (like a big city park) than multiple smaller sirens. If multiple voice sirens are needed to cover a large area such as a coastline, they should be installed so that there is a minimum of effective coverage overlap between siren sites, because the overlapping coverage areas are where the intelligibility suffers.

Well this is news to me. I guess I don't keep up with sirens anymore (but I'll still buy a 3T22 or SD10...if anyone has one.) It should be quite fun to watch what unfolds out of this. I'm in agreement with Travis, I doubt that Sentry will take a project this large, but I still hope for ASC. Best I remember though, the city of Lubbock was playing around with the idea of sirens with voice capability or something of similar words. If that's the case, we may be looking at a large Whelen system or Modulator system.

Shout out to Ben and Travis....we all need to get together soon! I'd like to travel and make a recording sometime again in Dumas or something.

I'm betting they go with Whelen.
