That looks like a Whelen 2905. Someone correct me if I'm wrong.

Thanks for those pictures, Joro!

No, those are Whelen 2805 sirens. You can tell that it is a 2805 by the position of the screen compared to the older 2750 and the newer 2905.
Compare the different Whelen Omni-Directional sirens:
Whelen 2750
Whelen 2805 (these sirens)
Whelen 2905
