Five operating modes suitable for a range of application temperatures
Ideal for environments that are dirty or smoky under normal circumstances
Drift compensation to ensure constant sensitivity
Remote test feature
The Discovery Heat Detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network, which produces a voltage output dependent on temperature. The design of the resistor network, together with the processing algorithm in the microcontroller, gives an approximately linear characteristic from 10ºC to 80ºC. This linearised signal is further rocessed, depending upon the response mode selected, and converted to an analogue output.
