The contract for a field investigation of the
effectiveness of residential smoke detectors was
extended to cover 36 additional tests investigating
details not completely covered in the first report. The
objective of the second phase summer/fall conditions
without air conditioning and to expand available
information on high volume, two story structures. The
effects of open windows, new technical developments in
photoelectric detector design, and the response of
semiconductor type residential gas detectors and
mechanically powered heat detectors were also included.
The tests reinforced the conclusions of the first phase
of testing. They showed that open windows have little
appreciable affect of life safety and detection times,
and that semiconductor gas sensing fire detectors
exhibit fuel specific response characteristics which
seriously degraded the effectiveness in certain types of
