Abstract

A fire sensor that can perform a sophisticated analysis of the outputs of radiant energy detectors, while minimizing size, weight, and cost, by employing a microprocessor to analyze the detector outputs. In one embodiment, an Intel 2920 Signal Processor is utilized as the microprocessor. An alternative embodiment incorporates an RCA 1802 microprocessor to achieve fire sensing while discriminating against false signal radiation.
