Conventional detector with fixed threshold set to 75°C, as established by standard EN 54-5 for class B/S. The control algorithms implemented mean it can be used in environments subject to rapid and considerable changes in temperature and is particularly useful for applications in dusty environments, with a high concentration of vapours and exhaust gases (e.g. garages, boiler rooms, kitchens, etc.). Microprocessor-controlled digital signal analysis. Low-profile design. Light indications by means of 2 LEDs with 360° visibility. Approved to EN 54-5.
