Jansson Alarm A/S is a Danish fire and security installer working out of Vejle in South Denmark. DBI approves it for automatiske brandalarmanlæg, varslingsanlæg, termisk brandventilation, mekanisk brandventilation and automatiske rumslukningsanlæg — 5 current approvals, 232.335, 024.004, 027T.046, 027M.034, 253.316 — under DBI Forskrift 253, DBI Retningslinje 232, DBI Retningslinje 24 and DBI Retningslinje 27. Its fire-alarm approval names 8 panel platforms — a Danish approval scopes the firm and the systems together, not the firm alone. DBI certifies the named individual as well as the company, and 1 certified person is listed against this approval. Holding five or more of the seven Danish fire schemes puts it among the small group of contractors able to take a building’s active fire systems as one package.
