Now the task is to identify these sirens...

[Daniel]

The first ones are definitely Cyclones. The others are single-tone and probably Taiwanese.

I'm pretty sure the first siren is electronic. I came on a picture of it in an online catalog somewhere and I'm trying to find it again now.

[Travis]

Looking closely at the second siren, it almost looks like it could also be an ACA product. (The first siren is indeed a cyclone, however, the motor looks like it is missing its outer housing. Are all the cyclone units in Taiwan like this?)

[SirenMadness]

Great pictures!

The first siren shown is a Cyclone, yes.
The fifty-horsepower motor looks smaller than I thought!

Doesn't the ACA Cyclone have its motor above the rotor?

[AllSafe]

Doesn't the ACA Cyclone have its motor above the rotor?

No, I'm quite certain the motor on a Cyclone sits below the rotor. It is much too heavy to sit above the rotor.

Very nice pic's.
They sure like their metal towers!
I take it that those must be very heavy?

[Robert Gift]

That cyclone has a 50 hp motor!?

I'm surprised the single-toned sirens pictured have screens.
The sirens on the mainland have a magnet which parks the rotor with the fins blocking the ports. No need for screens.

[SirenMadness]

All Cyclones have a fifty-horsepower motor, as rolled out of the factory.

[Robert Gift]

Wow!
What is the port ratio and diameter of that siren?
And weight?
