Embodiment Construction

[0077] exist Figure 1A and 1B Exemplary embodiments of aspirated particle detection systems 10 and 10A are shown in FIG. The system 10 is arranged to draw an air sample from the volume being monitored (eg chamber 16) and deliver the air sample to a particle detector 13 which may be a smoke detector. Sample air is drawn into sampling point 12 and travels via sampling conduit 18 to sampling conduit 20 . Sampling conduit 18 is typically connected to sampling conduit 20 via a T-junction 22 . A sample of air is drawn to a particle detector 13 for analysis.

[0078] There may be multiple such T-junctions 22 along a single length of sampling conduit 20 , thereby providing multiple sampling points along a single length of sampling conduit 20 . Furthermore, it should be understood that multiple sampling conduits 20 may be arranged, for example side by side, to create a grid or other geometric shape of sampling points.

[0079] The system is arranged such that the sampling duct 20 ...

Abstract

A sampling point assembly (30) for an aspirating particle detection system is described. The sampling point assembly is configured to be mounted to a mounting structure associated with a volume to besampled, the sampling point assembly being further configured to be coupled to a conduit to deliver an air sample from the volume being sampled to the conduit, the sampling point assembling includingremovable cartridge carrying an elastomeric valve (66) mounted to a sampling point body.

Description

technical field [0001] The present invention relates to a sampling point assembly for an aspirated particle detection system. Background technique [0002] In a suction particle detection system (for example using the Xtralis Pty Ltd produced In systems of the Smoke Detector family), a network of sampling pipes is arranged over an area to be monitored by a particle detection system. [0003] There are two main types of pipeline networks: [0004] • A system in which the sampling duct (or network of sampling ducts) includes multiple air sampling points. The sampling point may be directly connected to the pipeline or connected to the pipeline through a second pipeline referred to herein as a "sampling conduit". The sampling conduit is usually a length of flexible tubing with a smaller diameter than the sampling line, although this is not required. [0005] • A system in which the sampling points are directly connected to the particle detector without any intervening commo...
