Detroit has a system of 2001-SRNBs and recently added 2001-130s. All 2001s that were on fire stations have been moved onto concrete poles and have been fitted with solar panels. There are a number of old sirens from the previous system still standing; these are Thunderbolts (1000s and one 1000T) and...

My mom went to college out there...she told me that was a night called "hell night" and people would burn down buildings for no reason. Really sad and shady situation there. Were all the thunderbolts in Detroit 1000s? I've never seen a 1000T outside of the offset in Sterling Heights. Ther...

Would be cool to find a coverage map of the new Detroit system. Any Idea if the system is all 2001's or perhaps some mixed in Modulators like Chicago has? I'm assuming the new sirens are electronic since the following article says that they will have voice capability: http://www.freep.com/story/new...

Money issues and poor management.

Is the old system down? I know that there were a few 1000s still up last I checked, which wasn't very recently... I believe the old ones are still standing at least. I'm not very sure what's going to happen to them. But from what was given in the article, it sounds like maybe the 40 sirens that wer...

It looks like the folks at Detroit HSEM have basically completed the siren system upgrade, finally. It only took nearly a decade... Anyway here's a link to a short Fox 2 article regarding it. http://www.myfoxdetroit.com/story/28282210/detroit-plans-to-test-new-outdoor-warning-siren-system-this-weekend

The early ACA Allertronic is quite an interesting looking siren; it looks like a stack of 3 Eclipses. I too must ask however, what the devil is with the 2001? It's a 130 so it definitely shouldn't look like that just yet.

Well since I was home for break, and was interested in how the system sounds in Detroit now that sirens have been moved and added, I decided to do a recording of Detroit's sirens again. The 2001s sound a little lower than they used to, which I'm assuming is because they are running off of solar powe...

It sounded cooler in person. It was bassier than I expected. Actutally now that I think of it, it winds up a lot like the Grand Rapids Thunderbolt.

Just an update, some new siren locations have been added within the past couple of months. One of which is a new 2001-130 located on Outer Drive, right next to Renaissance High School.
