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.

This is why I just go ahead and buy the new ones that come with batteries that last 10 years. You’ll have to replace the whole unit when they die anyway.
This is the strat. They aren’t even any more expensive than a “cheap” smoke detector once you factor in the cost of batteries (not to mention the cost of all the sleepless nights when the infernal thing is beeping because the battery is low)
