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.
