]]> The ZIS-OSD optical smoke detector is designed for detection of a visible smoke at a start of a fire’s flameless stage when material starts to smoulder, and therefore generally, a long time prior to the appearance of an open flame and a noticeable rise in temperature.

The detector is designed to function in closed spaces in which, under normal conditions, smoke, dust and steam condensation are not present. Due to the implementation of analogue compensation for environmental changes, the detector is characterized by an increased resistance to changes in atmospheric pressure, temperature, and humidity.

The ZIS-OSD is an intrinsically safe detector designed for installation in explosion hazard zones. The detector can operate in Zeta manufactured re alarm system detector lines behind a proper spark proof separator.
