Question:
Michigan requires a license for BURGLAR alarm companies. But is a separate license required for FIRE sales,install,monitoring? Does anyone have this info at hand?

Answer: I misread your post. MSP handles Burg. I am not sure who handles Fire, but if the MSP cannot tell you, I'll call my brother, who is an electrical contractor in Mich. He was involved in the fire system at Detroit Metro Airport. He'll know for sure. Let me know if MSP aren't any help. I do know that in Detroit, an electrician cannot do fire unless it goes through a fire company and they are on site.
