Information Paper
Outlines the conclusions of a study by the Fire Research Station on false alarms from automatic fire detection systems (AFDS), based on the records of the Hertfordshire Fire and Rescue Service. It is set in the context of other studies from 1968 to the present time and stresses the importance of people and their behaviour, as well as the design characteristics of the systems. Currently most of them are of 'traditional' design but the paper notes an expectation of improvement as the new analogue addressable alarm systems become more commonplace. Quantitative data are presented concerning the effect of electrical storms on AFDS and some suggestions are made on measures to reduce the nuisance of false alarms.
