Conventional Fix Heat Detector
It can be said that the secondary signal of a fire alarm after smoke is an increase in ambient temperature. Thermal detectors are responsible for analyzing changes in ambient temperature. According to EN 54-5, two types of performance can be considered for a thermal detector: performance by reaching a constant temperature threshold and performance in the event of a sudden change in ambient temperature (Class S and R). In designing and manufacturing ZITEX heat detectors, these two classes have been considered.
