Abstract
A method of determining at least one point of entry of smoke into a smoke detection system, the system having a sampling pipe network including at least one sampling pipe and a plurality of sampling inlets through which an air sample can enter the at least one sampling pipe of the smoke detection system for analysis by a particle detector, said method including: determining a volume of sample air that has passed through at least part of the smoke detection system since a predetermined event or a value corresponding to said volume; and determining through which sampling inlet of the plurality of sampling inlets the smoke entered the smoke detection system based, at least in part, on the determined volume or value. Systems for implementing such a method and related methods are also described.
