Short title	A ceiling jet heats a sprinkler while frame conduction removes heat and the element warms gradually.
Image title	Top: a fire plume rises to a smooth ceiling and turns into a ceiling jet flowing towards a sprinkler head. Red arrows show convective heat from the hot gas to the heat-sensitive element; small dark arrows show heat conducted from the element into the frame. Bottom: qualitative temperature against time. The gas temperature at the head rises quickly; the element temperature rises more slowly and reaches the activation condition later. The time gap is the thermal lag. No numerical values.
