Abstract
Smoke detection sample points and systems are described herein. One smoke detection sample point includes a body having a chamber formed within the body, a first air flow conduit formed within the body having two ends and the ends being open, to allow air to pass through the first air flow conduit between an area to be sampled and the chamber, and a second air flow conduit formed within the body having two ends with one end being open and having an air seal, to prevent air from passing through the second air flow conduit between the area to be sampled and the chamber.
Claims20
A smoke detection sample point, comprising:
- a body including a chamber formed therein;
- and
- a shaft including:
- a first air flow conduit having two ends and the ends being open, to allow air to pass through the first air flow conduit between an area to be sampled and the chamber;
- a second air flow conduit having two ends with one end being open and having an air seal, to prevent air from passing through the second air flow conduit between the area to be sampled and the chamber;
- and
- a breakaway end cap attached to an end of the shaft to restrict movement of air through the second air flow conduit.
A smoke detection system, comprising:
- a central analysis device;
- a plurality of smoke detection sample points connected to the central analysis device via sampling tubes, wherein each sample point of the plurality of smoke detection sample points comprises:
- a body including a chamber formed therein;
- and
- a shaft including:
- a first air flow conduit having two ends and the ends being open, to allow air to pass through the first air flow conduit between an area to be sampled and the chamber;
- a second air flow conduit having two ends with one end being open and having an air seal, to prevent air from passing through the second air flow conduit between the area to be sampled and the chamber;
- and
- a breakaway end cap attached to an end of the shaft to restrict movement of air through the second air flow conduit.
A smoke detection system, comprising:
- a central analysis device;
- a plurality of smoke detection sample points connected to the central analysis device via sampling tubes, wherein each sample point of the plurality of smoke detection sample points comprises:
- a body including:
- a chamber portion having a chamber formed therein;
- and
- a shaft having:
- a first air flow conduit therein having two ends and the ends being open, to allow air to pass through the first air flow conduit between an area to be sampled and the chamber;
- and
- a second air flow conduit formed within the body having two ends with one end being open and having an air seal, to prevent air from passing through the second air flow conduit between the area to be sampled and the chamber;
- and
- wherein the shaft has a breakaway end cap that provides the air seal for the second air flow conduit.
