Fire protection licensing in Maine
Maine's Office of State Fire Marshal licenses fire sprinkler contractors under 32 MRSA ch. 20. Every contractor must retain a certified Responsible Managing Supervisor, who qualifies through NICET Level III in sprinkler layout or as a Maine PE with 5 years' experience. Sprinkler inspection technicians register separately. Fire alarm wiring is electrical work: it needs a Maine electrician license or the Limited Electrician license in low-energy electronics from the Electricians' Examining Board.
