- Abstract
- The malfunctions of automatic fire detection (AFD) equipment are examined on the basis of data collected from various sites in the UK and abroad. A scheme of categorizing events into a conveniently small but still comprehensive set of classes is suggested. Failure rates for several sites are derived for various categories of fault. Maximum likelihood and least-squares techniques were employed to estimate Weibull parameters and a summary of this analysis is given. Finally a novel report sheet is presented which forms the basis of a future data collection scheme.
