Sandbergs Trygghetsprodukter holds SBSC certificate 13-19 as anläggarfirma brandlarm to SBF 1008:3, valid to the end of 2028. It describes itself as a total security supplier in Svealand, handling risk assessment, project planning, delivery and follow-up for companies, municipalities and regions from Uppsala with offices in Stockholm and Gävle. The SBSC certificate is the verified fire evidence; the company’s own site does not detail its fire alarm offering, so fire is one line within a broader security business.
