Fire alarm keeps going off when roasting in oven. Advice please?
Make a cover for the alarm. Get velcro tape from a hardware store and attach one side of the tape to the alarm or to the ceiling. Then, make a cover out of foam rubber or whatever is convenient and attach the other side of the tape to the cover. Obviously, it needs to be airtight. Note that frames can be made by bending a coat hangar. Coat hangars can be cut by a chicken wire cutter, available at any hardware store.

When you cook, attach the cover and when you are done pull it off and put it away.
