Telehantering, founded in 1989 and privately held with around eighty staff, holds SBSC certificate 3-883 as anläggarfirma brandlarm to SBF 1008:3, valid to the end of 2029. Its regional sister companies hold their own certificates under the same norm — 23-541 in Gothenburg and 23-544 in Malmö — so the fire-alarm competence is certified at each regional entity rather than centrally. The group reports thirty SBSC certificates across fire alarm, intrusion and camera systems, with offices in Stockholm, Gothenburg, Malmö, Sundsvall and Östersund. Note that the www host has a broken certificate; the bare domain is the working one.
