Line Type Heat Detector

ADW 535

Design and function

The integrated ADW 535 line-type heat detector from Securiton, now available in the UK from Patol Ltd., 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 EasyConfig, or using the comfortable 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

Applications

Thanks to the extremely tough sensing tube, the 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 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, vehicle silos
  • Food industry, industrial kitchens, large commercial bakeries
  • Alcohol processing, distilleries
  • Chemical industry, refineries, oil tanks
  • Waste incineration plants
  • Outdoor applications: loading platforms (flying roofs), 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. under-floor monitoring in rolling stock; marine  applications

Sensing Tubes

Sensing tubes

Depending on the application, various sensing tubes are used (all of which have VdS approval):

  • Copper: standard applications, property surveillance
  • Stainless steel: food industry and high temperature applications
  • PTFE (Teflon): aggressive ambient conditions (e.g. chemical industry)
