Abstract
A detector unit for use in an aspirating detection system. The detector unit includes an aspirator for drawing air along at least one sampling pipe and into the detector unit; a sensor chamber for analysing a sample of the air drawn into the detector unit; a Venturi conduit through which the air is moved by the aspirator, the Venturi conduit including a first portion of the Venturi conduit and a second portion of the Venturi conduit, a cross-sectional area of the first portion being smaller than a cross-sectional area of the second portion; a pressure sensor configured to detect a differential pressure between the air in the first portion and the air in the second portion of the Venturi conduit; and a controller configured to determine a leak and/or a blockage in the aspirating detection system based on the detected differential pressure.
