Stator and roof made it home. Motor and rotor stayed behind. To pull out the rotor, the motor has to be in vertical position. And this is the real issue, since the nuts that hold the motor foot on the tripod are totally corroded and stuck. Even tried with a (very expensive!) nut splitter tool with n...

I've always wondered how that curved rotor blade design made it sound. Maybe not so pop pop poppy? I've been told by the manufacturer that this design achieves a deeper tone. While the rotor runs, the ports are never completely shut. Maybe a sound (or acoustic) engineer could explain it. 2pkisKuaKDs

The siren was exposed to weather elements for 40 years. I'm...

The school is located very close to where I live and the siren was disconnected for many years. I have always thought about getting it, but the lack of space (I already have many siren...

So the siren motor is DC or they use a converter?

Restoration completed! I have to tell you it was not easy at all. The siren bearings have been replaced and it was painted in the original colors. (Sikkens car paint) The siren has 8 ports and it can reach 92 dB @ 30 M at full speed.
