What are the recommendations for smoke/heat detectors to detect fire in a

Ideally, I would interconnect the detectors in the shop with the ones in
the house so I know about a fire when I am not out there.

Might be best to go with bi-metallic button type heat detectors.
Nothing to clog with dust. Only disadvantage is that you need more
of them.
