Your kidding me right???? Those people are being invaded and are being killed and YOU are discussing what the damn sirens sound like??? I realize this is NOT a political site, and that sort of stuff should not be discussed here.. But for Christs sake, try to be just a little respectful of the fact ...

The frequency of specific ports, other than the port count, is based on the RPM of the motor spinning. Electrical frequency (50 vs. 60 Hz) is also a factor since a siren's motor spinning at 3600 RPM on 60 Hz produces a different tone than that of the same siren's motor at 3000 RPM on 50 Hz. I will s...

You did a pretty good job on that, man! Judging by the fact you ran it up with a separate motor and belt in the video and the fact you said "visual restoration" and not just "restoration" or "full restoration", I'm assuming that you're probably going to restore the moto...

I was wondering if there were any pictures of the sirens after the fire! I'm surprised they both held up that well, considering the fact there was, obviously, a fire along with the fact they collapsed. They both look to be operable still (cosmetically at least) so I'm curious as to whether they were...

The motor's way too wide to be anything Federal, that's for sure. It doesn't look like anything ACA either so it can't be a modified Cyclone (unless it's just an aftermarket motor and then some) so it's likely something else like a Decot.

It's a Decot. Either made by Decot Machine Works, or Decot Engineering works, and looks to be maybe 8/12 port? There's a Whelen up the street unfortunately. It actually looks to be 6/10 ports. I attempted to count one of the rows of ports and it looked to be 6 or so. :o I see around 4 ports and 6 p...

I don't have any idea who made it but it looks to be 8/12. I guess that's something that can be of use.

Slight bump after about a week, but my friend sent me a video on Discord just now with a missile being launched, then another missile blowing up midair and hitting the ground with a Cyclone doing a steady pulsed signal and an electronic siren or two doing wail in the background of both clips. I have...

That gives me physical pain. What even happened to it to make it lean like that?

Looking at a different topic here, there were something around 100+ ACA sirens in Riyadh (or Saudi Arabia) so I guess it may have been a beefy order large enough to knock them out. I’m sure most have been replaced or scrapped but do you think any still stand or at least exist today? Someone out the...
