Abstract:
An ideal instrument for early fire detection would
combine high sensitivity. rapid response, automatic
self-testing and a low false alarm rate while generating
information specific to the location and nature of the
fire. Current fire detection strategies in large
buildings call for many point sensors such as standard
smoke detectors. In these systems, the false alarm rate
becomes unacceptably high because the overall rate is
the sum of the false alarm rate from each sensor. Even
if sensors are inexpensive, routine maintenance and
testing can be very costly when hundreds of detectors
are in use. Some new systems use multiple point air
sampling and a centralized, highly sensitive smoke
detector; this approach reduces false alarm rates but is
expensive to install, particularly in existing
structures.
