Abstract: A method of operating an aspirating fire detector system (3) including a fire detector (19), a conduit (7) having an inlet and being connected to the fire detector (19), a ventilator (15) configured to draw air through the inlet of the conduit (7) and into the fire detector (19), a pressure sensor (13) configured to sense the pressure of air being that is drawn through the inlet and into the fire detector (19), and a flow meter (17) configured to measure the flow of the air drawn through the inlet and to the fire detector (19).

Abstract: An aspiration smoke detection system for detecting the presence of a fire within a region of interest. The aspiration smoke detection system includes a smoke detection unit for detecting the presence of smoke particles suspended in air; and one or more local sensors located remotely from the smoke detection unit for measuring a property of air from the region of interest that is drawn into the aspiration smoke detection system. An inlet piece includes a sensor for use with the aspiration smoke detection system is also provided. A method of detecting a fire using the aspiration smoke detection system and a method of locating a fire using the aspiration smoke detection system are also provided.
