SKU: 58000-400 Category: Brand:


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”.


    • 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
