Abstract:
An aspirating system for detecting the presence of a product representative of a hazard and a method of detecting the presence of a product representative of a hazard in an aspirating system are provided. The system comprises: piping that includes a plurality of apertures spaced apart along the length of the piping; an aspirator for drawing air from outside the piping into the piping through at least one aperture, a detector coupled to the piping for detecting the presence of a product representative of a hazard; a generator of test stimulus for generating the product representative of a hazard; wherein the test stimulus generator is fixed in, near, or on the piping such that in use a test stimulus is provided adjacent to at least one aperture of the piping. A control means can be provided to control the activation of the test stimulus from the generator and the time taken for the test stimulus to reach the detector can be measured.
