1. A system for testing a device for detecting the presence of airborne particulate matter comprising:

  • a primary airflow conduit constructed and arranged to generate a primary airflow;

    a secondary airflow conduit constructed and arranged to generate a secondary airflow;

    a filter operatively positioned with respect to the secondary airflow to remove ambient particulate matter from the secondary airflow;

    a particulate aerosol generator constructed and arranged to generate an amount of airborne particulate matter and to release the generated airborne particulate matter into the filtered secondary airflow;

    an apparatus for measuring the amount of airborne particulate matter released into the secondary airflow; and

    an airflow combination location where the primary and secondary airflows are combined;

    wherein the device for detecting the presence of airborne particulate matter is tested by positioning it operatively with respect to the combined primary and secondary airflows so that it can detect the airborne particulate matter that was originally released into the secondary airflow.
