Performance of dual photoelectric/ionization smoke alarms in full-scale fire tests... In another test series, individual alarm sensor outputs were calibrated against a reference smoke source in terms of light obscuration over a path length (percent smoke obscuration per unit length) so that alarm thresholds could be defined by the sensor outputs....
