What are these?

I don't know if this has been posted before but what type of sirens are these. I get the feeling that the lower toned siren is a T-128 but what is the higher sounding siren? http://www.youtube.com/watch?v=qW9d9Zr0S9Y

Sounds like a 2001 and the one in the background sounds like a Thunderbolt on high tap

I still think the lower sounding siren is a T-128 though. I'm not sure if Omaha, Nebraska has 2001's

Omaha has a few 2001's in the west part of the city, and all of their T-128's sound a slightly higher frequency than others -- a "C" note rather than the usual "Bb". Ralston, which is a separate city surrounded by Omaha like Boys Town, has a 2T22 and a couple of Model 5's. Boys Town has three 3T22s, and Irvington has an STL-10 which carries for miles.
