METHOD FOR DYNAMICALLY ADJUSTING FIRE DETECTION CRITERIA

摘要

A fire detector with a maximum average response time of less than 1.5 minutes is obtained by combining a smoke detector with a CO2 detector that uses NDIR sensor technology. The smoke detector is used to detect smoldering fires and to help prevent false alarms attributable to the CO2 detector. The CO2 detector is used to rapidly detect fires by measuring the rate of change of CO2 concentration. A signal processor generates an alarm signal when a smoldering fire is detected or alarm logic indicates that a fire has been detected.
