The TSD-1 is a point detector designed to detect the early stages
of a developing fire. For this purpose, it is equipped with
a photoelectric sensor of visible smoke, as well as rate of rise
temperature sensor. The unique design of the measuring chamber provides high
sensitivity and omni-directionality, while a precise Hexamesh stainless
steel filter protects the chamber from ingress of contamination and small
insects. Detector configuration with DIP-switches and built-in parametric end
of line resistors facilitate connection of the detector to virtually any
control panel with a 12 V power supply.
