    14.2.3.1 Smoke transport time/pipe integrity test
    Introduce smoke in to the furthest sample hole in the pipe and time how long before the VESDA detector reacts to this smoke. A reaction is deemed to be an increase of 2 bars above the normal bargraph reading. It could also include an alarm condition, however, if this is the case, any alarm delays should be set to zero before the test.
    パイプのサンプル吸引口のうち一番離れた位置にある吸引口に煙を導入して、その煙にVESDAが反応するまでの時間を計る。
