I live in a house containing five flats. Each flat has two smoke detectors and one heat detector and a call point . These are all connected to a common control panel. Should this equipment , detector heads and control points, be inspected and tested every six months as well as routine weekly tests or is it sufficient to inspect half of the equipment every six months?

In a converted house of 5 floors with a flat on each floor, must the entrance doors to the flats be fire doors?
