Old smoke alarm

Electrician:

Took this out of a customers home.

Looking to give it to a collector rather than the garbage.

Not in great shape.

Free to pick up.

I live near the Farm and home supply in Highridge MO

Yeah, that is where most of these relics of life safety history come from, heh.

That’s great, thanks! Wish more people did that!

That’s to be expected with age I guess.

Sadly if it weren’t for that I for one would love to take it off your hands, since I live nowhere near you (most collectors in general would probably prefer shipping as well).

I’ll take it if you can ship to Texas. I’ll be willing to pay for it.

I’d be interested in buying this from you! I had one of these a while back but sadly traded it and have been desperately searching for a new one. I would recommend you list this on ebay as that’s what most collectors use for getting alarms such as myself.

Alright I’ll look into posting it onto eBay, I’ll make another response on this once I have it posted (probably within the week).

I’d be interested in any fun facts about the specific device I found. My 5 minutes looking into it didn’t give me much.

Good idea (even if that means you’ll have to deal with Ebay’s ridiculous fees nowdays).

As for fun facts:

  • It’s a First Alert-brand (though possibly labeled as “Smoke Alert” as that was the brand’s original name) model SA769AC smoke detector made by BRK Electronics
  • It has an ionization sensor & an electromechanical horn (the latter of which buzzes due to the detector being AC-powered)
  • It’s powered by 120VAC & has no battery backup (the latter didn’t really become commonplace until the 1980s)
  • It was likely made sometime in the 70s or 80s.

Here’s a question for you: any clue if it has a red or green power LED? (since, even though most First Alert detectors with that design have a red LED, I swear once seeing a photo of such a unit with a green LED instead)

Made the eBay post.

Thanks for the fun facts!

No idea on the color of the LED it was not on when I took the unit off the wall. It has the clear casing around the LED. My guess would be that it’s the normal Red

Sure thing!

Ah, yeah, thought so. Wait…does that mean that it doesn’t work? (going by the fact that the LED was not on, which it should have been if the detector was properly getting power)

Apparently I just didn’t notice due to the paper blocking it and how the first thing I did was disconnect the power.

Also this is probably from 1976-1978 because of the older rectangle base and the slot

Can you please post the link to make it easier to find?

Ah okay. Odd how the button doesn’t seem to line up perfectly with the LED.

Those are definitive identifiers of that year range?

Curious if anyone wants to beat the $20 offer I got for the smoke detector or if I should skip the auction.

I have no idea what this is worth.

I would suggest letting it bid out since these can sell for way more than 20
