How it works: Fixed Temperature Mechanical Heat Detector


I always thought that two contacts would melt together or something. I didn’t know that something jumps inside the detector.

so if you wanted to it could be fixed and back installed

Not really, you’d still need a disc and a plunger, because remember they assemble as one piece but then melt and separate into two…

Same here. The technology in a unit like this is simpler than I thought.

Very informative video! I always wanted to see how one worked. And now I know.

cool I did not think that is how they worked.

So this is why you can hook these up to the same Line as pills but not smokes? That makes sense

What? Really? These aren’t supposed to be on the same circuit as smoke detectors?
