- Abstract
- This paper is concerned with a statistical analysis of false alarms from fire alarm systems in eleven hospitals within one Area Health Authority (A.H.A.) of the Department of Health and Social Security. Data from the Local Authority Fire Brigade covering a two year period is analysed using various statistical techniques. These include the classificaion of causes of false alarms; calculation of alarm rates; analysis of variance to investigate the influence of the time and day of occurrence of alarms; Weibuil analysis of the times between false alarms; investigaton of the growth/reduction of false alarms with time using a non-homogeneous Poisson process model. The analyses are combined to obtain a global model of false alarms.
