Description
The Axis AX UL Heat Detector monitors temperature by using a single thermistor which provides a voltage output proportional to the external air temperature.
In the Axis AX UL Heat Detector, the five response modes correspond to the five ‘classes’ as defined in UL 268. The classes in this standard correspond to different behaviour, each of which is designed to be suitable for a range of application temperatures. All modes incorporate ‘fixed temperature’ response, which is defined in the standard by the ‘static response temperature’.
