Lotek A/S is a Danish installer working out of Sønderborg in South Denmark. DBI approves it for automatiske brandalarmanlæg, varslingsanlæg, termisk brandventilation and automatiske rumslukningsanlæg — 4 current approvals, 232.398, 024.056, 027T.064, 253.307 — under DBI Forskrift 253, DBI Retningslinje 232, DBI Retningslinje 24 and DBI Retningslinje 27. Its fire-alarm approval is scoped to 16 named panel platforms, which is an unusually broad installed base to be certified across: a Danish approval covers the firm and the systems together, never the firm alone. DBI certifies the named individual as well as the company, and 3 certified people are listed against this approval.
