Abstract
Aimed at the problem of false alarm and missing alarm caused by information uncertainty existing in the fire alarm
system, Bayesian network (BN) is proposed to analyze fire alarm system. The paper elaborates the internal logic
relationship between the fire alarm and the physical-chemical characteristics generated in the process of fire burning
by analyzing fire mechanism. Based on defining node variables in BN, multi-sensor Bayesian network model for the
fire alarm system is established in Netica. Probabilistic inference and sensitivity analysis of finding node verified that
analyzing fire probability through the multi-sensor Bayesian network model is feasible and effective.

1. Introduction
Fire (as a disaster) is one of the most damaging disasters in modern society, how to prevent people's
lives and society's wealth from harm caused by fire has become a major issue facing on currently. Fire
alarm system is an important means of fire prevention, its function is to sample the signal from fire scene
process and determine whether the fire occurred. At present, the main research areas are intelligent fire
alarm system based on multi-sensor. Multi-sensor data fusion, neural network, image processing
technology and fuzzy logic decision have been used for fire alarm system
[1], [2], [3], [4]
.
In engineering practice, the system structures, control objects and working conditions in different
systems are mutative, there are many uncertainties, we hope that fire alarm system can cope with
uncertainty problems and has functions of adaptive and self-learning. BN applied in the paper is an
