Implementing High Reliability Fire Detection in the Residential Setting

摘要

The purpose of detecting fires early is to provide an alarm prior to when there is an environment which is deemed to be a threat to people or a building. High reliability detection is based on the supposition that it is possible to utilize a small number of sensors to ascertain unequivocally that there is a growing threat either to people or to a building and provide an estimation of the seriousness of the threat. The current generation of fire detection systems is designed to respond to smoke, heat, gaseous emission or electromagnetic radiation generated during smoldering and flaming combustion. This paper will demonstrate that these same low level signals can be utilized to achieve the goal of producing earlier detection, while improving reliability. This allows us to reduce the time to detection at the same time reducing the error rate for both false alarms as well as missing fires. Large commercial fire panels are beginning to implement such advanced algorithms for reliable fast detec tion; however, the focus of this work is to achieve such detection in a way that can be implemented in a lost cost, low power, EPROM which will be suitable for residen tial systems.
