Great Video! Some Notes: The Whelen 2906 Is Part Of A Line Ranging From the 2901 (Which Has One Of Those Sectors) And The 2910 Which Has 10 Of The Sectors. The Sirens (Over There) are Most Likely For Severe Weather, But The Sirens Before Them (More Similar To The Sirens In LA) Were Probably Meant For The Volunteer Firefighters To Get To The Station Because Of A Fire Before The Introduction Of Pagers And Radio. All Of The Sirens In This Video Were Whelen Sirens, And Whelen Specializes In Electric Sirens, Which Means That instead Of A Motor Chopping Up Air, They Are Basically Huge Speakers, And You Can Hear What They Sound Like If You Just Search Up Anywhere On KZfaq: "Whelen 2906 Siren Test" Or "Whelen 4004 Siren Test" One More Note (Last One I Promise) The Last Siren Was Indeed A Whelen 4004 And It Probably Replaced An Older Siren That Was At The Fire Station For The Above Listed Reason, Along With The Second Siren

Most sirens in South Mississippi are Whelen Vortex R4s (or 4004s, whatever is the newer of the two). Haven't heard the ones here test in ages. You can find some old mechanical sirens here and there in places like Hattiesburg and Gulfport/Biloxi, but Laurel is literally nothing but old sirens, just like the rest of the town being old looking. Mostly Thunderbolts, but I know there's an Allertor in Hattiesburg.

Great video! Whelen sirens are some of the best sirens made today!

Great video Douglas as always! Here In SoCal we actually have some Whelen sirens, there is 2 at Azusa Pacific University, 2 on both Harvard Westlake campuses in LA, and ones on Military bases such as Fort Irwin, Palms MCCS, MCAS Miramar, as well as down on Coronado Island in San Diego with 3 rotating Whelen Vortex sirens like the one in the end of the video just to name a few. There used to be a whole system of 50 Whelen sirens for the San Onofre Nuclear Generating Station down in South Orange County, but last year 39 of the 50 were removed early last year due to the cities around the plant not realizing the other uses for them for non nuclear related stuff such as Tsunami’s and Earthquakes since that whole area down there is costal and is a hazard to those incidents. Nearby Newport Beach and Huntington Beach have siren systems as well for those emergencies, and if the cities around SONGS took over the sirens, they are already up and installed, so no additional cost to install them from the ground up like what the other places nearby like Huntington and Newport did. Except the Whelens used for SONGS where 2800 series sirens which are older then the 2900 series, but both are cosmetically the same minus some small differences, and a big difference with the 2900 series is they are louder and have a higher effective range, as well as clearer voice messages. The only Whelens from SONGS’s system that remain are the 10 that are on MCAS Camp Pendleton which are now owned by the base and used with their separate siren system. Good news is that one of the cities that had SONGS’s sirens will be getting new sirens as the poles that were in that city were left up. And it sounds like the city will be getting 2900s which is an upgrade from the 2800s that were there before.

Whelens are electronic sirens which are just big speakers

If you don't know read this whelen sirens actually have speakers and people speak through them

Alright, I’ll explain how the Whelen Engineering sirens work. So these sirens do not have any sort of motor or spinning device inside of them. There is actually multiple speakers inside of them. Hope this helps!

that at Ladimir Park in horn Lake ms

In muscle shoals where I live we got the same siren

7:30 Hey, you missed a Model 5 on the water tower back there...

Awesome! Whelens happen to be my favorite of the various models. Also, the Sledge Whelen is a "Whelen Vortex R4" the 4 means the amount of speakers seated in the siren, as there are 4 throats on the siren, there can be 1-4 speakers, for example a Vortex with 3 speakers would be a Vortex R3, but it would still have all 4 throats, just one wouldn't have a speaker in it. Whelen also produces another model exactly like this one, the 4000, though it uses a different rotator style, allowing it to know which direction it is facing, and is also voice capable, while the Vortex is not. Oh and the big box is like a tone generator with speaker amps inside, and it houses heavy duty batteries so the siren would still be operable if the power were to go out. If you have anymore questions I will be glad to answer!

That’s new I thought you do los Angeles

I think I seen a Whelen 4004 in Fort Worth and grapevine

If you make it to East Tennessee at some point, we are going on a road trip around Middle and East Tennessee. 😎

Come to Louisiana! We have some great sirens out here as well!

If you ever find yourself in Huntsville Alabama please message me and let me know! I'm pretty sure our area has the biggest concentration of siren enthusiasts in the world. By the way, all of these sirens in the video are radio controlled. You can see the radio antennas on all of them right above solar panels. I actually own parts of a whelen 2800 series siren, and a whelen 2900 series siren. I'll be more than happy to show you them and how they work! And also it's pronounced: WHEE-LIN

The Whalen’s are different because are electronic not electronic like the ones in la

The third siren you saw was the whelen R4. Some R4s have the finback, and some don't. There's also a 4004 but the screen on it is different than the R4s

Small world! I subscribed to your channel earlier this year, but I just so happen to originally be from Mississippi and most of my family lives in Memphis. If you will be in the Memphis area, they test their sirens every Wednesday at 3:30. They have a few ACA P-50's, which are the largest and loudest sirens to be produced in the modern era. There is one close to the Mississippi state line that was refurbished within the past couple of years (close to 3884 Sewanee Rd, Memphis, TN 38109). Memphis also has a lot of Thunderbolts. It's a pretty neat system because there is a lot of new sirens mixed in with the old and they are all still working.

So how the whelens are powered are through speaker drivers, not choppers

Whel en

Memphis has a huge system that tests every Thursday at 3:30 PM if you ever wanted to hear one. Also at 8:03 there was another Model 7 on the water tower behind the fire house

the purpose of it it’s for tornado or a bomb attack

Looks like we just missed each other haha.

#welensiren

You were wondering how the power works on these sirens, the bottom of the controller box has space for two car batteries, of which are charged by the solar panel. The whole siren runs off these two batteries, and as a result, can work during a power outage, even at night. Hope this helps.

Those are basically giant Bluetooth speakers. Accept they are radio activated, not Bluetooth. Here is a video of one of these. A 2810. 4 towers bigger. kzfaq.info/get/bejne/fpdpZquhudK4Y6s.html

Whelen wps 2906 this is not a motor is a speaker

can you go to Magee Mississippi theres 4 sirens there i live in magee

herrin il?

Haha, did anyone notice the Model 5 on the water tower behind him at 7:49

Great video ! A video of somewhere else to change it up a bit ! Nothing spinning in them, they're electronic sirens, basically a pile of speakers, you can plug in a mic on the controller and talk on them, or even play music by plugging your phone in the controller ! The third one is indeed a Whelen 4004 and is rotating. Other manufacturers make similar sirens, like Federal Signal and their Modulator, or American Signal Corp. (ASC) and their iForce 😉 ! They're much more modern sirens, made since the 90's I believe and still made today. As for how they sound, Whelen has the list of tones on their website www.whelenmassnotification.com/siren-warning-tones/ . There are also numerous videos of them on KZfaq. Oh and Whelen is pronounced "wheel-n" 😉.

Is this a deed in there makes the siren sound spin and it makes the noise come out is is it dead? I did it sounds off that’s all from my comment.
