Building fire detection and location procedure samples air from monitored rooms and uses blower clearance and redetection time delay to locate detected fire

摘要

A building fire detection and location procedure samples (6) air from the monitored rooms (R1-n) through a common suction (5) tube system (3) and when a fire is detected (7) blows (8) out the tube and continues sampling until fire is again detected and located using the delay to redetection and previous measurements of flow rate and blow out time. Independent claims are included for equipment using the procedure.
