Are these two models essentially the same siren, other than the obvious visual differences (housing, projector cones, etc.)? I'm assuming the projector cones make the STH-10 louder than the Model 5, but are the tonal qualities of both models the same? I haven't heard either model in person but I can...

These images are from Google maps in Evergreen, Conecuh County, Alabama. In 2011 only the Whelen on the left was there (which is the last time street view was updated), by 2013 the mystery siren popped up next to the Whelen, and by 2015 the Whelen was removed, leaving only this new device. What is t...

Siren in Cherokee, OK (could this be a T-128 or T-135?): https://www.youtube.com/watch?v=NVkjqXxvD_M Same siren starts at 4:19: https://www.youtube.com/watch?v=OWL-Sfywd3Q Siren in Stigler, OK (Could this one be a Whelen?): https://www.youtube.com/watch?v=3WYVh6axS0I

Does anyone know what sirens the city of Altus, Oklahoma has in its system? I'm a little confused by what I've found. I know the city has 12 sirens. I found a post on here from 2009 that says they have 7 Model 5s and a news article from 2013 about siren repairs that shows a picture of a Whelen (howe...

Do you think they're using a custom tone? In the first video at 2:35 you can hear a very natural sounding wind down. I don't know a lot about ATI, but I was under the impression that ATIs don't have a wind up or wind down.

Hi siren people, Can anyone identify the sirens in these videos from Russellville, Arkansas? I've heard that Russellville has ATIs but the sirens in these videos don't sound like ATIs. I feel like there could be some lower tone mechanical sirens mix. Thanks https://www.youtube.com/watch?v=V5YtF_ZoSt...

I was wondering if anyone could identify the siren that is sounding in this video. The video is from Barbourville, Kentucky. The video is not mine. Is it a Whelen maybe?

First of all I think most sensible people would agree that purely from an emergency management standpoint that FS-2001s are very good sirens. They are quite reliable and they serve their intended purpose. When it comes to siren enthusiasts it seems there are 2 main reasons many don't like 2001s: 1. ...

When I asked for help with Nebraska I got extremely useful answers, so I thought I'd try with Iowa. It is also lacking in info: I've found that, outside of the few largest cities, information on Iowa sirens is hard to come by. I've searched the forum but still came up with very little. If you have a...

I have a question for moderators: Since this post yielded such useful and comprehensive information, I was considering posting a new topic just like this one for Iowa (and maybe a few other states). My concern is cluttering up the forum with these kinds of topics. Should I stay away from starting an...
