But it's not a false alarm. Smoke detectors detect smoke; toast burns; smoke detector triggers. That's a real alarm.
There are two solutions: 1) make it easier to temporarily dismiss the alarm. 2) read the instructions and place the device properly
Scenario B 1) Toast burns, catches fire and your whole kitchen is burning down. 2) You run like hell
Why would being able to disable a false alarm easier make it any less safer?
Edit: I'll also point out that EVERY single time we cook a steak in a cast iron pan in our apartment the smoke alarm will go off. It's really annoying I have to be the one trying to figure out how to silence the damn thing.
