Also I’m a big fan of you on YouTube!
Apparently first alert used to make brown colored smoke alarms.
Yes, though the only such model I know of is the SA79TA (the “TA” stands for “travel alarm”, as it was designed to be taken with you on a journey & hung up wherever you slept: very clever of First Alert!).
First alert also made the sa77w which I can’t seem to find any information on but I saw it in an old First Alert advertisement if you look in the comments
Unrelated but I kind of wish GE home sentry’s were less rare because there is one on eBay currently but it is way too expensive
Yep! The First Alert SA79TA they also made a SA76RS in brown that was shown in an old advertisement and a few catalogs from the 70s. I’ve also found a SA79TA in a house.

I have never seen this in my life but I think it might be a Dicon that was rebranded by Jamison
This was in an apartment building so it’s probably part of their system (Wheelock 30 series)
I like to know what the most common on eBay squealer horn smoke is? (sorry I didn’t word this very well)
Detection Systems DS200HD.
Oh? Huh…
That’s just how it is sometimes, nothing we can really do about it (other than of course pay that much for valuable pieces of history).
Honeywell TC49A or TC89B & System Sensor W3-268-series (or one of its many rebrands).
Neat! Kinda unusual that someone would install an alarm that’s meant to be portable though, heh.
BRK 4919 to be specific.
That’s another detector that I know I’ve seen somewhere else & learned the identity of, but I forget: maybe someone else can name it.
Going by the location of the test button that’s a BRK 1839ACI (or one of its two known variants, the 1839ACWI or 1839ACWN).
American Sensors COS2000 combination smoke/CO detector.
Given where the test button is on that unit that’s likely an 86RAC.
Right away I recognized that detector as being one of the many ones NLind owns, & it’s a Pyrotronics FB-1B, which is apparently a rebranded Ten-Tek (even though I believe the circuitry is very similar to that in your average 80s Dicon unit. Very rare in any case of course).
Neat! (especially since the 7002T is probably much more commonly seen, especially indoors)
BRK 769AC/769AC-I/Smoke Alert SA769AC or 77R I think.
Detection Systems DS200HD on MB200-2W or MB200-4W base.
Could also possibly be the hardwired version, the CD-200A.
TC49A you can get closer I just wanted to show you all of the things
I thought the TC49D was the hard wired version
Ah okay.
Oh, right you are: the battery version then, heh.
Do you know what’s the most common squealer horn smoke alarm is cause I kinda want a squealer horn but most the ones I know of are really expensive and rare
No clue to be honest, though when it comes to the most common squealer horn in general, it seems like one of Kobishi’s is (probably the CLB-27).
I mean brk 1839aci’s are pretty common I feel like on eBay but they don’t have a squealer horn they have a mechanical buzzer
Well as you may know AC & DC detectors from back in the day both use the same kinds of electromechanical horns, the way they sound just depends on which kind of electricity they’re powered with.
So does that mean that if I powered the horn inside of one with DC power it would sound like squealer horn?
Maybe, though the horn also has to be made for either AC or DC just the same (at least some of Kobishi’s are made for both kinds of current I think however).
