Sampling point assembly

A sampling point assembly for an aspirating particle detection system, the sampling point assembly being configured to be mounted to a mounting structure associated with a volume being sampled, the mounting structure comprising a panel-like portion having a first side and a second side and a space passing through the panel-like portion between the first side and second side that is able to receive the sampling point assembly, and at least the first side of the panel-like portion being exposed to the volume being sampled, 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 assembly including:

• 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, said inlet being configured to be maintained in fluid communication with the volume being sampled to receive an air sample therethrough, and said outlet being configured to be coupled to the conduit such that the air sample can pass through the bore to the conduit;
• and
• a fastening mechanism configured to secure the sampling point body to the mounting structure, said fastening mechanism including 1) at least one mounting surface arranged in use to support the sampling point assembly on the first side of the panel-like portion of the mounting structure, and 2) at least one fastening actuator for holding the mounting surface against the mounting structure from the first side of the panel-like portion;
• a cap mounted with respect to the sampling point body such that it extends over the fastening mechanism to conceal the fastening mechanism and the inlet from view from the first side of the panel-like portion of the mounting structure.
