Amazing article on my all time favorite siren series. Great job!

Commenting so I can read the rest later. Awesome read so far as usual.

Once again you stun me with your knowledge! Also, didn't some of the 500s use the STH-10 chopper/stator?

Yes - as noted above, the 500-SH used the STH-10's motor core (fan, drum, motor). The only difference is it had an extra shaft stub on the other end to drive the rotation belt. The 500-SH shown in that video had its baffles and intake removed for maintenance access.

Far as I know what killed most of the 500 sirens was rotator failure, either from the gearbox placement (oil sitting on top of a seal) or that damn belt that required splitting the siren in half to replace. I really haven't heard of any motor failures on those, most of them seemed to be the victim of politics.

I know from experience that the 10/12 500 is a BEAST of a siren, that really packs a punch. https://www.youtube.com/watch?v=Rdh0O5nV5Jc

Very nice information and a great read.

SuperBanshee, your knowledge never ceases to blow my mind!

Once again an awesome article!

In regards to the versions of the 500 that used the Model 5 choppers, were there any single toned ones manufactured that utilized the 8 port version of that chopper? Awesome article.
