Berg & Wigum AS is a Norwegian installer at Trondheim, Trøndelag. It holds FG-760 Brannalarmforetak in the FG-Kontroll register for design, installation, technician and inspection, valid to 2028-01-11. Its certificate spans four or more of the FG roles, which is the full span the scheme offers: FG scopes an approval by role, so a firm may design without being approved to install, or inspect without either.
