Mount a smoke detector just outside the shop door and connected with the
others in the house. Vacuum it off once a month. No compressed air. Keep
the shop door closed whenever possible. I dont know about heat detectors.

The shop will be a dedicated building seperate from my house. I don't
know any reason why I couldn't extend the smoke alarm circuit from my
house to get interconnected if I wanted.
