Abstract
Devices, methods, and systems having insect guards in devices and systems for aspirated smoke, gas, or air quality monitoring are described herein. One aspirated smoke, gas, or air quality monitoring unit includes a detector module that includes at least one particulate sensing chamber within the detector module and an air inlet connecting the sampling tube to the particulate sensing chamber allowing communication of air from the sampling tube to the particulate sensing chamber; and a spiral shaped insect guard positioned within the inlet.
Claims17
An aspirated smoke, gas, or air quality monitoring unit, comprising:
- a detector module that includes at least one particulate sensing chamber within the detector module and an air inlet connecting a sampling tube to the particulate sensing chamber allowing communication of air from the sampling tube to the particulate sensing chamber;
- and
- an insect guard positioned within the inlet, wherein the insect guard is a spiral shaped removable insect guard mounted within the inlet.
A modular aspirated smoke, gas, or air quality monitoring unit, comprising:
- a base having a plurality of sampling tubes mounted thereon;
- a number of removable detector modules connected to the base the detector modules each including multiple particulate sensing chambers within the detector module, wherein each particulate sensing chamber has an air inlet connecting one of the sampling tubes to the particulate sensing chamber allowing communication of air from that sampling tube to the particulate sensing chamber;
- and
- a spiral shaped insect guard positioned within each inlet, wherein each inlet includes one insect guard.
An aspirated smoke, gas, or air quality monitoring system, comprising:
- a sensing unit having a detector module that includes at least one particulate sensing chamber within the detector module and an air inlet connecting one end of the sampling tube to the particulate sensing chamber allowing communication of air from the sampling tube to the particulate sensing chamber;
- a sampling point connected at the other end of the sampling tube;
- and
- a spiral shaped insect guard positioned within the inlet, sampling tube, or sampling point, wherein the spiral comprises a number of coils of wire and wherein the wire has:
- a circular cross section;
- an ellipsoidal cross section;
- a rectangular cross section;
- a quadrilateral shaped cross section;
- or
- a tear drop cross section.
