Oh wow!! I knew I saw an old 80’s FX with a green light somewhere! Many years ago I saw one in a hotel room. That brings back some memories.
That FX1218 probably came out in the late 80’s. It seems to be a competitor to the 86RAC.
Oh yeah, by the way, to get those stubborn Youtube tags to show properly as a video, only use the alphanumeric video code and paste that between the Youtube brackets.
So instead of the whole link, only use the video code portion of it. Everything after “watch?v=”
I was going to call dibs on the Kwikset, but I found this one to call dibs on.

(the alarm to the top right)
I had one of these in my original collection.
If I get this lot, if anyone wants one of the Code One 2000s let me know. I’ll probably be willing to part with 2 of the Chemtronics heats.
Woahh that smoke is unusual. A Gamma? Kind of looks like a cross between a GE, a Gateway, and a Montgomery Ward. Do you know the era/original manufacturer?
Sadly the one I had didn’t have a label (might have worn away), so I’m not sure who made it.
BTW Here’s me with my first collection.
In fact if I win this auction, I’ll have a duplicate of almost all the alarms on that board. (note some I kept.)
Note I’m trying to keep some of the stats I do know of (batt. type, horn type, sensor type, etc) secret until if I win the auction, for I’ll make a video of it.
Wow, good find, it seems really rare
^This picture is possibly one of the rarest smoke alarm collection photos in existence.
I’m really interested in those Universal Smoke Signal alarms. The square one and the round one. The square one resembles a BRK 79DCRI (An alarm I have). The round one looks like some kind of weird First Alert SA76RC knockoff of the early 80’s.
The square Jameson React is cool and very rare too.
What is REALLY weird though is the Lifesaver you had in this photo. It says Sears but the cover looks like a standard Lifesaver like benson41011 has. You say it has a 5/6 horn pattern with an adjustable pitch… Is this a DC squealer that does 5/6??
I take it the BRK AC alarm is the 769AC. The cover just looks really sharp and less round from this angle.
I’ve never seen anything like that Ci-Toh alarm before. Very rare and cool.
About the Smoke Signal:
The SS-200 is indeed exactly like the 79DCRI, in fact the covers are almost compatible — the 200’s cover can fit on the 79DCRI (though the test button offers resistance), but the 79DCRI’s cover catches are not cut the same as the SS-200’s, so they don’t quite mate with the -200.
•The “Sears” is a Lifesaver (mislabeled it, D’oh!) and is an F900D but the newer version with a piezo. They had this design before they switched to the compact version, like this Battery Operated Smoke Detector on Ceiling Stock Image - Image of danger, prevention: 12436003 About the horn: I was able to adjust the pitch on it by turning the horn itself, but the unit I currently have does not do that. Must have been a little quirk with that one alarm. I found this one by luck at the Missouri Council of the Blind Thrift Store in Kansas City. I heard a BEEP! while browsing the hardware section, so I dug through the stuff and found it. My aunt lived in the KC area and she was a thrifter also. Sadly she died in '97, I miss her so…
•The Ci-Toh used an 11.2 volt battery, basically a smaller version of the 12.6 volt one. Found that at a local thrift store.
Ohh I see about the Lifesaver. Sometimes piezos can do that. I’m sorry about the loss of your aunt too. My condolences go out to you and your family.
Was Smoke Signal an offshoot of BRK? Their alarms seem way too similar. Maybe that’s why Smoke Signal doesn’t exist anymore, because of a lawsuit from BRK 
What’s the difference between SS and BRK circuit boards? I’m especially curious about the round SS-700.
Smoke Signal was made by Universal Security Instruments (USI). Even though the brand doesn’t exist anymore, USI still retains the SS-xxx numbering for some of their models.
Cool. I’ve seen some modern USI smoke detectors, particularly this one, a battery powered ion alarm that was in a dorm room. I wouldn’t call it rare, but most alarms nowadays are BRK/First Alert or Kidde/FireX.
Take a look at these.

They’re made by BRK (probably rebranded as Edwards) and notice #1 how they use the 77R/76RS’ sensor and #2 the PCB has 800 Series printed on it. I saw these at the Mark Twain museum years ago and thought they were some variant of the 769AC. I think these look like the offspring of the 769AC and an 1839 series.
BTW I asked the seller and they said if the whole system doesn’t sell they’ll part it out.
Super cool! I’ve never seen detectors like that before. They look pre 1839 series. I bet you they are system smokes from the late 70s. They look like they have a test button, but they have no LED or test switch on the board. Pre System Sensor (1984).
That big ESL looks like one I have but mine has the bimetallic 135F heat sensor. Mine is also labeled as Fire-Lite.
Wow, those seem like a cross between an SA769AC, an 1839N, and an SA76RS
On a slightly unrelated note, carbon monoxide detectors use temporal 4 Coding. But before they used temporal 4 they used to beep in strange patterns. I used to have an old first alert that beeped two seconds on and a few seconds off. I’m on my iPod so I can’t link a picture but I can tell you what it looked like. It was rectangular and had three lights on it. Alarm trouble and power. It looked like a big bar of soap. it was from the late 90s early 2000’s.
Just won the lot with the super rare Gamma alarm!! Also forgot to mention since no one bid on the Kwikset I got that and it came today. I’m currently in the process of editing the video so expect that soon.
Again if anyone is interested in the Code One 2000 alarms let me know, and again I’ll probably be willing to part with some of the Chemtronics heat detectors.
Can I request that this topic be stickied? It’s a very active thread.
Anyway, has anyone seen Gentex 24VDC/120VAC detectors anywhere?
Like they can use either?
I own one.
Actually, they’re separate detectors.
I used to have this old smoke alarm
the noise of it always hurted my ears
We had this smoke alarm for 22 years
