The smoke alarm in our dining room was going off every time we opened the oven door. It was annoying to us, but it completely freaked out our dog Madison - to the point where she would hide in the bedroom closet and shake for 20 minutes.
So, I got a plastic storage container and two of those magnetic cabinet door latches.
I took the guts out of the magnetic catch
Glued the "strike plate" to the ceiling next to the alarm.
Glued the magnets to the storage container.
I "stick" the container over the alarm when we are using the oven or cooking something smokey on the cooktop. The only problem so far is that MrsWD, at 5'10", isn't tall enough to stick it up. I'm looking for something lightweight and about 12" long to attach to it as a handle. This will allow MrsWD to use it and also minimize the chance of forgetting to take it down.
