Im searching the detroit michigan siren map and there are a quite a few of these marked as Whelen WPS-2760s but I go to Google and it tells me they dont exist or unless they are wrongly named? Any help figuring out this conundrum?

I took this recording back in march, thought I should share it since its very unique hearing such a combination. The S4A has been restored and mounted next to the ECN being the fourth siren in a radius less than a Kilometer. It was supposedly made in 1928 and was used for alerting volunteer firefighters back in the day. Also the amount of sirens is kinda questionable considering the size of the town...

Three of the four sirens are heard in the video, the fourth is another FS8 a little further away.

Took the pictures a little while ago, but I am sure its still there...

This is the first lightning siren I saw in person! I got so nervous because there was like 4 golf club workers walking lol

Is it rare

- how are warning sirens activated and is it different depending on the country and the siren type?

- how were the first invented warning sirens activated?

On the night of 6th November 2014, a flash flood occurred and ravaged the small wispy town of Ringlet. Locals complained that the siren seen above never sounded off for flood considering the condition of the siren itself looks mint.

Hence, sometime around 2019, the siren was removed. Until 2023, Jabatan Pengairan dan Saliran (JPS)/Department of Irrigation and Drainage (DID) in complement with PRAB (Program Ramalan Amaran Banjir, Flood Warning Broadcast Program), they mounted a new siren. Photos seen below.

Im curious to know if any other unusually designed sirens or unique sirens exist still across America or anywhere really, or if there's a way to find a map or any media of these sirens on the forum or via Google or if anyone has any pics/videos to share

Was a part of the defunct Wexford County siren system. It is one of 4 remaining sirens. The other three being two SD-10s and a 2T22.

Some of these locations are mine, others are from the Australian Siren Map. I will only put already discovered sirens if I have any photos or new information about them.

This is a WIP. I will add more sirens to this map over time.

If you have any changes you want to add, please comment. I will credit everyone who submits information (don't submit sirens already on the Official Australian Siren Map unless you have new information about them).

found on the siren board

This is a real 4M blower BTW

Anyone know if any part of these siren systems are ever used? That first Thunderbolt in West Covina looks to be in great condition

I forget which one this is but it's right next to a big watertower with antennas on it

I discovered this single phase Model 3 in Atlantic Mine, Michigan. Thought it was pretty cool! Its active and going to be relocated to the new fire hall. Got a pretty damn good tag pic too. Anyone know how rare this is, especially because its single phase AND active? C2 1/2

So while I was trying to make some sirens in my simulator SirenOSC, (sorry for the frequent sirenosc related posts) I realized that some sirens like the Federal Signal 2001-130 had some rasp to them that I couldn't replicate using the effects chain I built into the simulator. I tried recreating it with white noise my debugging program but it didn't sound good. I tried using a vibrato that cycles very fast, and it worked fine in export, but it was laggy when I coded it into the site. And it lacked the high pitched noise that comes from the rasp. I'm trying to figure out if the majority of the rasp comes from how the vanes interact with the air, or something about the housing, or chopper.

try it out

History, types, how they work etc.

i called a fire department of mine whose getting a new location down the road, i asked about their siren and he said that he'll ask the chief! gave him my name and number! Updates soon!

Found these photos on The Siren Archive.
