    Discovery heat detectors have a common profile with ionisation and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. For the European standard version of the detector, the five modes correspond to five “classes” as defined in EN 54-5. The classes in this standard correspond with different response 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”.

    Key Features

      • Ideal in environments that are dirty or smoky under normal conditions
      • Well-suited to warehouses, loading bays and car parks
      • Unaffected by wind or atmospheric pressure
      • Five response modes
      • Remote test feature
