Funny story, I didn't even know cyclones continued to be made under ASC as the C-125 until a few years ago lol. Must say, reversed wired cyclone 120's/125's and P-50's definitely have a unique and instantly recognizable sound. Nice video!
@RamFett I think ASC went through two different nomenclatures for its sirens since the switch, starting with the OM/RM series of rebrands before moving to the tempest line, and then discontinuing and streamlining the line to what it is today. The best example I can think of is the P-50 becoming the RM-135AC, then becoming the T-135AC, then being replaced by the T-135AC/DC.
@MichanaAlerting That makes perfect sense. I really like the utility of the RM/OM designations, but having a cool name like Tempest attached to it has a certain appeal as well.
@RamFett I like the RM/OM naming too. Though I also do like the tempest name. To me it's like a spiritual successor to the Penetrator, Allertor, Howler ETC names.
There is no damper. It's wired incorrectly, causing the rotor to spin backwards (pushing less air, less resistance, so faster), which produces the higher pitch.
@NFDTornadoalarmNFDYTHELLO I don't believe it is coded. The box you're referring to is just a junction box, if I'm not mistaken. The pictures I've seen of 3 signal Cyclones, the solenoid boxes are much larger.
@@scarlet-e4x892 What I meant that the ACA P-50 and Cyclone 120 use the same rotor and stator. The Cyclone-120 was produced first but got replaced by the Cyclone-125, which is just slightly different. The Cyclone-120's rotor and stator were then used to make the P-50, which flips the rotor 90 degrees and adds a big projector and a rotator. Meaning it's just a rotational version of the Cyclone-120. And all these sirens use the same port ratio, which means they produce the same tones.
Man that 12 port screams when reversed. Nice one!
@ACAFan101 Thanks! It reminds me of Milwaukee when so many of our P-50s were reversed back in the day.

Thanks! Yes, ASC still produced them. Apparently, they also went by the name OM-125-AC as well.

@@RamFett Ah. Similar to how the T-135AC (P-50) was also known as the RM-135. You learn something new everyday.

Despite it being reverse wired for years, I can still hear it from my house nearly 4 MI away as the crow flies
I believe it! This one was still quite loud up close.
reverse wired cyclones sound awesome from a distance, but are very underwhelming up close. nice recording
I was surprised by how loud this one was. Thanks! I love the creepy, higher pitch at a distance.
@ yeah it sounds awesome! have you heard the sirencon 2023 ambience recording?
@@vantaaax I have! The echoes are 👌
I wonder how most all cyclones are reverse wired
The tag usually even includes a wiring diagram to show how to wire it correctly and the installers still mess it up constantly...
Tornado siren
0:11 1.25x speed
The damper is closed?
There is no damper. It's wired incorrectly, causing the rotor to spin backwards (pushing less air, less resistance, so faster), which produces the higher pitch.
@ huh okay but it’s coded hence the name and also the way the housing is. The housing on this model could fit a damper in it
There is also what looks to be a solenoid box where the wire connects to the siren but I could be wrong

@ ah okay sorry about that lol thanks for the clarification
it sounds like a P50 to be honest
It's basically a P-50 but vertical.
Same port ratio (8/12) but this one is reverse wired
@@TreinspotterMenno okay..but serious..it really sounds like a P-50....

@@scarlet-e4x892yea because it’s the same stator assembly 🤦♂️
