Abstract: A method of particle detection in an aspirated particle detection system, the system having a sampling pipe network and a particle detector. The sampling pipe network includes at least one sampling pipe in fluid communication with the particle detector, a plurality of sampling inlets through which sample air can enter the at least one sampling pipe, and an opening in the at least one sampling pipe upstream of the plurality of sampling inlets, wherein the opening has lower flow impedance than any one of the sampling inlets. The method includes drawing sample air to the particle detector through the air sampling network; analysing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.
