Hello! I've been having a slight problem lately, This is what it is.
So, I've been looking all over the internet for Info about the 2001 Series, TheSirenBoard's Wiki, FedSig's Website, Etc. No luck. so I tried looking for it on TheSirenBoard, but Again, No luck. So I am making a Post about this, If anyone could link me to any posts that have this type of Information, Please do.
Thank you!

2001-DC was set to 2 RPM from the factory. But could be changed to 4 or 8 RPM.
2001-SRN could also be set to 2, 4 or 8 RPM.
2001-SRNB was set to 3 RPM.
2001-130 was set to 3 RPM.
That's all the info I got for now. If I find anything else I will update the info. Hope this helped.

When you say rotor are you talking about the actual rotor in the siren's chopper? The 2001 Series, with the exception of the Equinox, uses a Model 3 rotor which is 14 inches in diameter. These don't spin at a particular RPM, but depending on the condition of the motor and the voltage going to it they can spin anywhere from 3100 to 4100 RPM. Typically the don't go much faster than that, and when they spin slower than 3000 RPM something is probably wrong with the batteries or the rectifier. The Equinox uses a 14 inch rotor as well from the Eclipse I think. Early SRN's (2001-DC round and square back) will typically do around 3450 RPM like a normal 12 port siren, but it's not always the case. The later model SRN with the fatter cone all the way up to the 130/Equinox and 508 typically do something around 3600, but there are some known to spin slower.

Thank you for sharing that, SoundMaster 391 and DJ2226! Any other additional info is greatly appreciated if anyone has some! And again, Thank you!
