Gas detector for use with an air sampling particle detection system
First Claim
1. A system for detecting a condition in an environment, the system including:
- a particle detector arranged to detect the presence of particles in an air sample;
a sampling pipe network including a plurality of air sample inlets in fluid communication with the environment and the particle detector;
an aspirator to draw an air sample from the environment to the particle detector through the sampling pipe network; and
and at least one gas detection apparatus having a housing and being arranged in fluid communication with the sampling pipe network at a location upstream of the particle detector, and at least one gas detector sensitive to a target species;
said gas sensor being arranged to detect the presence of the target species in at least part of the air sample flowing in the sampling pipe network.

Abstract
An apparatus and methods for detecting the presence of gases is described. The gas detection apparatus includes, a housing adapted to be in fluid communication with a duct of a particle detection system, and at least one gas detector sensitive to a target species arranged in fluid communication with the housing to detect the presence of the target species in at least part of the air sample flowing in a duct. In one form the gas detection apparatus forms part of a system for detecting a condition in an environment that includes, a particle detector; a duct system in fluid communication with the environment and the particle detector and an aspirator to draw an air sample flow from the environment to the particle detector.
