ADW Line Heat Detection

NSW 02 9644 7144 QLD 07 3252 5366 VIC 03 9544 2211 WA 08 9349 2972 Introduction Where conventional fire detectors reach their physical limits, the SEC- ADW - 535 line-type heat detector comes into play. The intelligent line-type heat detector works perfectly, even under the most difficult conditions. Whether the fully automatic monitoring of large areas, resisting corrosive gases, extreme humidity and high temperatures, or differentiating between false alarms and real danger – the list of requirements for a state of the art line-type heat detector is both long and detailed. Design and function The integrated SEC- ADW - 535 line-type heat detector combines a proven functional principle with the latest developments in sensor and processor technology. A sensing tube filled with normal air is installed in the area to be monitored. A fully electronic pressure sensor permanently records the pressure in the sensing tube. This is monitored constantly in the processing electronics and compared with the alarm criteria. Diverse setting options are offered directly on the device via Easy Config or using the ADW Config tool for perfect adaptation to existing environmental conditions. The Dynamic Heat Watch (DHW) technology ensures that a brief temperature increase caused by the ambient conditions does not result in a false alarm. Applications Thanks to the extremely tough sensing tube, the SEC- ADW - 535 can be deployed in many applications where conventional fire detectors do not work. With its long service life and maintenance-free design, the SEC- ADW - 535 is also ideal in applications where detection properties must remain constant over the entire product service life. Typical applications: - Tunnels: road tunnels, metro and railway tunnels, utility and cable tunnels - Underground garages, industrial vehicle s, silos - Food industry, industrial kitchens, large commercial bakeries - Alcohol processing, distilleries - Chemical industry, refineries, oil tanks - Waste incineration plants - Outdoor applications: loading platforms, historical bridges, fuel warehouses, towers - High-temperature applications such as: paint shops, steel plants, kilns, climate chambers, gas turbines, engine test benches - And many other applications, e. g. underfloor monitoring in rolling stock, marine applications Sensing tubes Depending on the application, various sensing tubes are available (all of which have VdS approval): - PTFE (Teflon): Standard material and for aggressive ambient conditions (e.g. chemical Industrie) - Copper: standard applications - Stainless steel: food industry and high temperature applications SECURITON SEC -ADW- 535 3
