Abstract：According to the characteristic that the firefighting‑general blower can be used both in peacetime and in fire，the reason why the firefighting‑general blower in the smoke bay not on fire shall stop in the event of a fire is analyzed. An idea that the control circuit of the firefighting‑general blower shall be added with a firefighting linkage stop function is put forward，and suggestions and examples on the measures to implement this function are given. Finally，the matters needing attention on selection of relevant atlas are analyzed.
