Hekatron UTD-531 Universal Temperature Detector

Hekatron UTD-531 detects open fires with and without smoke development. It is used wherever a rapid development of the fire and high temperatures are expected or, due to environmental iinfluences, smoke detectors cannot be used. The sensing chamber contains an NTC temperature sensor which continuously measures the ambient temperature or the rate of temperature rise. If the set alarm point or the specified rate of rise is exceeded, the detector sends an alarm to the control panel. The detector can be controlled to a clearly defined extent from the control panel. For example, the response characteristics can be modified as a function of the time of day or the event. The UTD-531 is available in three sensitivity ranges according to EN 54-5, detectors of Classes 1 and 2 being rate-of-rise detectors and detectors of Class 3 only fixed temperature detectors.

This item is no longer available, and is replaced by the TCD-573.
