Rare Smoke Detectors

Sears did indeed rebrand the BRK 3000. It had a different cover but the BRK version had a cover that looked like the SA769AC. I have seen many many SA67D’s. BRK’s version of the 83R had a different cover but the same components. My uncle has a 67D in his kitchen that always goes off whenever he’s cooking something. We then all get up and wave whatever is in our hands at it. The SA76RS had a regular squealer horn, and i don’t think any models had piezo horns. I think the SA76RC was the only detector to have the piezo horn with three holes (though some versions had the modern horn). After that, all their detectors had the modern piezo horn with only one hole. found a few videos of these BRKs / first alerts:
