There are 2 quadrens located in MT Prospect Il
There's at least one in IL still. I believe Bill recorded it a couple of years back.
Not entirely sure on the RM-130, but I do know that the PN-15 was offered in single tone once the name changed to the RM-127; never seen a dual-toned RM-127 (yet...).carexpertandy wrote: ↑Sat Jan 12, 2019 4:33 pmInteresting how the PN-15 and PN-20 were only rated at 125 and 127 decibels originally, and were later rated at 127 and 130 when they were changed to RM.
While I haven't seen a dual tone RM-127, there is a picture of a dual tone OM-117 out there. I'm pretty sure that they offered them in dual tone when they were still being sold.Chicagosiren-hunters wrote: ↑Mon Jan 14, 2019 4:44 pmOnce again, 4J hits a gold mine!

They were mentioned in the ACA demo video from 1982 by Jim Biersach himself, so that’s certainly a possibility; that was my hypothesis myself.FSThunderboltfan1000 wrote: ↑Tue Jan 15, 2019 6:53 amThe country that bought all the sirens that did not pay for them was Saudi Arabia.
I remember seeing a few videos from the middle-east of sirens sounding off for a missile strike back in the 1990's. I know there were a few Cyclones sounding off in pulse with a mixture of other electronic sirens sounding off also.fire_freak_57 wrote: ↑Tue Jan 15, 2019 1:26 pmThey were mentioned in the ACA demo video from 1982 by Jim Biersach himself, so that’s certainly a possibility; that was my hypothesis myself.FSThunderboltfan1000 wrote: ↑Tue Jan 15, 2019 6:53 amThe country that bought all the sirens that did not pay for them was Saudi Arabia.
If Saudi Arabia did purchase the sirens but never paid for them, how come there’s no recordings of any ACA sirens there? Unless they’ve been replaced by this point...
