I am glad you have a smoke alarm in the garage I am now thinking how mine died in the garage and I sleep right above it. If it was me in your position I would make sure I used a linked fire alarm system where if one goes off they all go off. It will buy you precious extra seconds getting your kids out as fires can spread incredibly fast.
Yep, ours are all wired together. Sometimes when I am a little over-enthusiastic searing a steak, I think they can probably hear the ruckus a quarter mile away when every single alarm goes off at once. Makes me feel somewhat secure that I'll be woken up if there is ever an actual fire.
