These might be all-in-one gas detectors, and the blue LED might be a power indicator.
Again, this was already talked about.
You are correct it is but still its a fake spectralert classic

Has anyone seen this or have a video this. I want to learn about this knockoff. Hard-Wired Doorbell Horn + Strobe for Deaf | HW-LDHS2
Yeah that’s another one of those generic SpectrAlert knockoffs: this one actually appears to have a substantial amount of text on its label though (including claiming that it meets various US organization’s requirements & that it’s assembled in the USA: likely story), along with multiple tones as opposed to just 3 like most. Also of note is the fact that the strobe is actually capable of flashing one of five different colors: amber, blue, green, red, or white! (& while there is an option to turn off the sounder, there’s still only a single 2-screw terminal block meaning full independent control of the sounder & strobe is not possible (with others I’ve sometimes seen a second 2-screw terminal block where the rotary dials are however)
have you seen or heard it? video? I’ve never seen a knockoff alarm do a horn sound.
Most knockoff SpectrAlerts all make the same 3 sounds from what I’ve seen/heard, but this particular one (which as the label indicates can make more than 3 sounds) I don’t think anyone’s made a video on yet (probably because it’s extremely obscure). I also have not heard one for myself yet either & likely never will.
Have you ever seen a knock off spectralert advance.? is this one? https://www.keepsupply.com/cti-sha-120-amber-horn-strobe-120vac-white-body-amber-lens-weather-proof-mounting-backbox-labeled-ammonia
btw does this look similar? https://www.tequipment.net/Bacharach/3015-3076/Gas-Detection-Accessories/
No, & given the amount of original SpectrAlert knockoffs it’s probably unlikely that one exists: China just seems too obsessed with knocking off the original SpectrAlert-series for some reason.
That’s a legit blank white SpectrAlert Advance with colored lenses.
Like the above example that’s a legit device: in this case a blank gray Edwards/EST Integrity (it technically doesn’t belong to the Integrity series but the design is the same as such) with a red lens.
why did it say sha-120 by cti?
btw this looks like the p2475rlz Fire Strobe Light And Siren Fire Alarm 2 Wire Conventional Strobe Sounder For Fire Alarm System Horn Strobe Sounder - Buy Red And Blue Fire Strobe Lights In Building strobe Light 220v red And Yellow Strobe Lights Product on Alibaba.com
That appears to be the model number that the third-party company (Calibration Technologies, Inc., or “CTI”) who sells that particular version decided to call it.
It could be a legit original SpectrAlert or a knockoff, I’m not sure: a Youtuber (who’s name I currently forget) I believe once said that SpectrAlert production continued in China for a while after it stopped being made in the US, & that the design was changed/updated a few times (including I think to have terminals on the mounting plate instead of on the alarm itself).
I found so many sounders that look like roshni and flashni and there is a brand called cemen in Thailand that has sounders that also look the same.
I might buy one of those as a joke
show me the sounds if you buy one
It basically sounds like a dollar store fire truck from the videos I’ve seen of it
I saw those at a Subway restaurant in Houston, Texas day before yesterday. It was tied to a CO2 detection system, and it had a yellow lens. Looks like some of these are becoming…UL listed.
I did some research and the ones that are bootlegs that are white / with colored strobes are from AliExpress
No surprise there honestly: AliExpress seems to sell a lot of things from China.
