Fire Alarm Sensitivity

Couple of things on the sensitivity of fire alarms. I know they are made to detect the slightest smoke, even before we see it, but ours often goes off when I make muffins and a slight drip of the batter on the pan burns. DH stands up by it fanning it with a pot holder and that stops it. How many of you have to do this too? My poor Mica, goes running for a place to hide when it goes off. With it's sensitivity, is a toaster going to set it off? We've been RV'ing in various towablesl for close to 20 years and have been making toast under the broiler, so I thought I would buy a little inexpensive two slice toaster. Is it going to set off the alarm with all those little bits of crumbs that are going to burn? I'm debating whether continuing to broil my toast.
