Short title	Three alarms over six months followed by an occupant hesitating before moving.
Image title	A six-month timeline with three false-alarm markers. Below it a stepped line drops after each alarm, labelled credibility falls. On the right an occupant hears the next alarm and hesitates, shown with a question mark. At the bottom a bracket from the alarm to the moment the occupant starts moving is labelled pre-movement delay. A note says the three-alarms-in-six-months figure is an example from BS DD240 guidance, not a universal threshold.
