Technical Examples
  1. A fire detector and method for generating an alarm signal in response to a fire uses an NDIR CO2 sensor to generate a detector signal based upon a 15? absorption band of CO2 and generates an alarm signal when a signal processor receives the detector signal and a preselected criterion is met that is indicative of the onset of a fire based upon an analysis of the detector signal using a detection algorithm that relies upon a trending pattern of the detector signal such as recognizing a substantial drop in the detector signal strength. The NDIR CO2 sensor can also generate a reference detector signal based upon a 9.0? neutral band with a FWHM=0.5? while the signal processor utilizes a detection algorithm that is based upon a synchronized output signal representative of CO2 concentration to generate an alarm signal when a preselected criterion indicative of the onset of a fire is met.
