Heat detector, 80°C, EN54-8 (IP56)
Heat detector for use in wet areas. The detector gives alarm when reaching a fixed alarm limit, 80 oC if the temperature increases slowly. A rapid increase in temperature may cause alarm at a slightly lower temperature. For use in hazardous areas zone 1 or zone 2. To be connected via zener barrier BZ-20. Often used in areas where smoke detectors are not to be used due to the false alarm problem. The detector comprises a built-in alarm indicator (LED).
