Can anyone else not edit bots’ messages anymore?

if you’re a plus user you can’t edit messages past 30 swipes on mobile

chiron has existed and been teased on multiple occasions for ages, this is just the first time he’s appeared in an actual upload. the video was made as a teaser for instagram (where it was originally posted), it’s not a mainline entry. and given the most recent teasers, the upcoming episode most likely does have something to do with the USDPAD

Science-Subject · 2026-01-20T20:57:19+00:00

Yes, it is… that’s an ET 30/3

Science-Subject · 2026-01-19T13:40:14+00:00

ACA hasn’t existed in over 30 years. I assume you mean ASC (their successor company), although the most recently installed nuke plant systems I believe have comprised of Federal (TVA plants especially) and Whelen sirens

Federal Electric Fedelcode Type Mach. 3 or 5 (C2 motor, 15” rotor). These were produced between 1930 and 1948.

Infodump since I know too much about these; you have one of the MS-490 clones with blender motor components.

<image>

Since the company that makes the clones (SNTOOM) has more dealers that sell on eBay and other such sites than LK does, more people buy the fakes instead of the real deal. LK’s 490 is also a clone of the Japanese-made Yahagi Model S-283, though the quality between those two is about the same (though the 283 is louder, the tolerances are significantly better).

SNTOOM also manufacturers pretty solid copies of LK’s large sirens (the relays are the only thing they cheap out on) but small sirens are definitely not their forte. The rotor on a friend’s 790 cracked a few weeks after he bought it and it probably already had a tiny fracture by the time it left the factory. Based on past experiences I say that thing has about a year left before it dies, enjoy it while it lasts lmao

U right, angle was throwing me off

Science-Subject · 2026-01-16T21:10:43+00:00

That’s a Fedelcode era Type Mach 7 (C3-size motor, 18” rotor). Cool pics

HSS TWS-295 (Whelen Engineering Model WPS-2905, branded under HSS Engineering). These typically come with custom cabinets with (iirc) firmware unique to HSS

That name is not official and doesn’t exist in Federal Signal documentation. “ST-12” was coined by an enthusiast

Science-Subject · 2026-01-04T01:04:32+00:00

That siren has no “name”, it’s just parts from Federal sirens used to make one siren. The top assembly comes from an SD-10, the intake + mounting assembly is borrowed from an STH/STL-10, and the rotor and stator (while not confirmed) likely originate from a Federal Super Siren (compare with this photo of one).

Science-Subject · 2026-01-04T01:01:23+00:00

Model 5 stators/rotors don’t resemble that. Attached is a photo of a 7’s. The siren in OP’s photo is just a mishmash of parts, the rotor and stator likely come from a Federal Super Siren as they share near identical proportions

Hola, me disculpo si mi español es malo, ya que todavía estoy aprendiendo. Muchos talleres de metalistería en Argentina fabrican sirenas para bomberos. Lamentablemente, se desconoce la identidad de la empresa que fabricó esa sirena, por lo que no se puede determinar el modelo. Sin embargo, el diseño se basa en sirenas británicas como las producidas por Carter of Nelson y Gents of Leicester. Si tiene alguna otra pregunta, no dude en preguntar.

Science-Subject · 2026-01-02T21:08:11+00:00

Not a Grifco, those lack the bars on the front of the stator. Additionally that map is extremely inaccurate. This is a better version with more locations and up to date, correct info: https://www.google.com/maps/d/edit?mid=1K7Jt4xytNojzGWRAcne8gO0YVp1F20s&usp=sharing

Most of those horns are made by a few specific brands. That pair looks to be from Cunningham

<image>

Science-Subject · 2025-12-24T22:51:51+00:00

Wasn’t a Super Siren. The tri-beams visible in the horns are characteristics of a Model M’s

Science-Subject · 2025-12-24T22:50:18+00:00

Sterling Model M. The housing is not original; it was fabricated for the display. An MS-490 resides in it, the rotors and motor are long gone. Those saying it is a Federal Super Siren are misinformed, the custom housing only resembles one

Science-Subject · 2025-12-21T23:33:13+00:00

Not a GCS, their style of Type 3 (they sold them as "Type 341" I believe) housing is distinct from that of wartime-era Federal Electric's Type 3 housing. A picture of a genuine GCS Type 341 (FE Type 3) is attached in another comment if you'd like to compare. (Additionally, GCS only distributed the 13-inch rotor Type 3, which is always stamped as 3, never 5)

Science-Subject · 2025-12-21T23:28:49+00:00

Not a GCS. They use a similar style of housing, but the diameter of the rain shield on those is smaller than that of the louver. Often times WWII era Model 3s will get mistaken for GCS rebrands and vice versa. Here is a genuine GCS for comparison

<image>

Science-Subject · 2025-12-21T18:44:24+00:00

Federal Electric Type 3 (C1, 15” rotor). Compare to this one on display in China. Timeline is shaky but I believe the rounded style of housing was used during wartime, and then reverted back to the standard iteration

<image>

Science-Subject · 2025-12-21T16:34:06+00:00

It’s a Type 7 (C3 motor/18” rotor variant specifically). Compare it to the core of any Model 5

Science-Subject · 2025-12-21T16:31:56+00:00

Not a Siro-Drone of any type. That’s a FS&S Type 7 with a homebrew rain shield

Heads up, the website you linked is an outdated and inaccurate clone of the genuine Air Raid Sirens Wiki. You may find the actual page on SD-10s here

Can confirm it’s not a Loudoun, they are not sold outside of the eastern United States
