The Siren Board

I wonder what the reaction is now after Joplin got blasted.

all those damn homeowners association types care about is how (censored) valuble their home is, well when it's destroyed, it's not worth anything

actually, wheelens can be just as loud, if not louder, just because it's an electronic siren doesn't mean squat.

if a car hits that thing where it is, the driver was either drunk, distracted, or a flipping idiot.

If a car hits it, it doesn't make it bad; it makes it a case of kill one save a thousand.

I genuinely hope they just remove the siren.

Why?

My local Wheelens are not louder than the Tbolts they replaced.
Back when we had the Tbolts, you could hear the neighboring sirens in the background.
Now i can only hear the closest wheelen siren to me. No more sirens singing in harmony..

As far as a Whelen not being louder than a T-Bolt, it all depends upon how many speaker cells the Whelen has, as the decibal rating can be equal to, or a few decibals greater than, a T-Bolt. I think that the Whelen 2810s and 2910s have decibal ratings of 129 or 130 at 100 feet, whereas a T-Bolt is rated at 126 or 127 decibals at 100 feet.

There are also two seperate sound modes that Whelen sirens use: one for test purposes and one for actual emergencies, and this was clarified to me by a Whelen rep a few months ago. The test mode is quieter, though it's still loud, but for actual emergencies the siren is much louder. I can attest to this, as I live about a quarter of a mile away from a Whelen WPS-2806, and when we have a Tornado Warning the siren is MUCH louder than on the monthly test day. Seriously, when we have a Tornado Warning it's balls to the wall louder! It's a big difference than when it's just a test.

This past Sunday evening we were under a Tornado Warning (part of the same system that caused the Joplin tornado) at 5:45, but I noticed that the siren was quieter, like in its test mode, and even my 12 year old daughter noticed this (she's not even a siren freak!), since she was in her bedroom with the door closed. She said that had she been sleeping she wouldn't have been woken up. I had to go to her bedroom and tell her that the sirens were going off.

So, as far as a Whelen not being louder than a T-Bolt, there are variables to consider.

My closest Whelen is an WPS-4000 series, 4 cell, rotating model.
next closest is also an 4 cell, rotating.
3rd closest, is an 8 or 16 cell rotating model.


Will also say, the Whelens were also not always put in the same place the Tbolts were.

Same thing in St. Louis County, as far as the new Whelen 2910s not being placed where old sirens are at now. Whelen came in and did a survey as to where to place the new sirens for the best possible coverage, so most are not next to the old sirens.
