  • Patent number: 10184831
    Abstract: A method for calibrating a test light to simulate a fire includes measuring a baseline resistance induced in a sensor cell of a two-color detector in response to a controlled fire. The method includes monitoring a test resistance induced in the sensor cell in response to exposure to emissions from a test light and adjusting the emissions of the test light until the test resistance of the sensor cell equals the baseline resistance of the sensor cell to achieve a calibration setting for the test light. A test light for a detector includes a housing and a first LED within the housing having a first emission wavelength. A second LED is within the housing. The second LED has a second emission wavelength. The second emission wavelength is different than the first emission wavelength.

  • Patent number: 9976925
    Abstract: A linear-thermal-sensor testing system has a signal generator and a reflection analyzer. The signal generator generates a series of damped sinusoidal impulse signals each of a different frequency, and transmits the damped sinusoidal impulse signals to a first end of the linear thermal sensor. The linear thermal sensor generates a reflection signal corresponding to each of series the damped sinusoidal impulse signals at a plurality of electrical discontinuities in the linear thermal sensing array. The reflection analyzer receives a reflection signal from the first end of the linear thermal sensor. The reflection signal has indicia of electrical properties and locations within the linear thermal sensor for each of the plurality of electrical discontinuities. The reflection analyzer calculates the electrical properties and the locations within the linear thermal sensor based on the indicia of the received reflection signal.
