摘要： A method of particle detection in an aspirated particle detection system having a sampling pipe network and a particle detector. The method includes drawing sample air to the particle detector through the air sampling network; analyzing 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.

摘要： A method for determining correct performance of a sampling pipe in an aspirated particle and/or gas sampling system. The method includes causing a change in airflow n a sampling pipe of the aspirated particle and/or gas sampling system that induces a change in at least one airflow property within the sampling pipe, and detecting an effect of the change in said airflow property. Also disclosed is a method for determining correct performance of an aspirated particle gas sampling system. The method includes determining correct performance of a sampling pipe in the aspirated particle and/or gas sampling and determining correct performance of a detector in the aspirated particle and/or gas sampling system, wherein a test fluid is introduced to the aspirated particle and/or gas sampling system at or near the detector.

摘要： A sampling point assembly for an aspirating particle detection system includes a sampling point body having a bore running from an inlet at a first end of the bore to an outlet at a second end of the bore, the inlet being configured to be maintained in fluid communication with a volume being sampled to receive an air sample therethrough, and the outlet being configured to be coupled to a conduit such that the air sample can pass through the central bore to the conduit. A fastening mechanism includes at least one surface adjacent the inlet and arranged in use to support the sampling point assembly on a first side of a mounting structure, and at least one fastening actuator for holding the surface against the mounting structure from the first side. A cap conceals the fastening mechanism and inlet from view from the first side of the mounting structure.
