You don’t say where you are? Here’s what our City of Sydney council regulations say:
“Every year the owner of a building or premises must provide the City and Fire and Rescue NSW with a statement certifying all fire-safety measures work properly. This statement must be assessed by qualified personnel and be displayed prominently.”

Check your local council, I think you’ll find that you should be having your fire systems audited every year.
