Yesterday while cooking I set off the smoke detector, no I did not burn anything. They go off when I cook over a high heat. And yesterday once they started going off they would not stop. I ended up having to disconnect them all (they are hard wired with an interconnect) and I replaced them this morning. Aaaaaaaand let me tell you, I had a sleepless night last night knowing there were no detectors installed.

I work in EMS. When we respond to house fires in the middle of the night there’s kind of two different ways they go. When people have smoke detectors and their house catches on fire in the middle of the night they’re the ones who call us and we get on scene to find them outside their home in their pajamas, watching their house burn, very shaken up but ok. They never need anything from us ambulance-wise except maybe some blankets. When people don’t have smoke detectors in their homes and they catch on fire in the middle of the night a neighbor or passer-by calls the fire in and we get on scene and the firefighters are dragging bodies out to us.
As I mentioned in another comment, I almost died in a house fire. I had an aerosol can in a pile of clothes that caught fire from a heater, that can exploded and woke me. Otherwise I would have slept through the fire.
Your comment hits me really hard (I am sure not as hard as being on scene where they did not have detectors). But reading some of the dismissive comments I was starting to think I was over reacting, you assured me I was not.
