Product Overview

Where conventional fire detectors reach their physical limits, the SecuriSens 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 SecuriSens 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 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

Thanks to the extremely tough sensing tube, the SecuriSens 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, such as; 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, such as; 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

 

Plus many other applications, e. g. under-floor monitoring in rolling stock, marine applications

 

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)

 

Integrated line-type heat detector for 1 or 2 sensing tubes (Double Tube Technology)

Based on proven technology

Fastest heat detector with fully programmable response behaviour plus differential and maximal valuation

  • Intelligent alarm verification with DHW technology (Dynamic Heat Watch)
  • Available as standard and Heavy Duty version (with Atex approval)
  • Sensing tubes of copper, stainless steel or Teflon withstand extremely severe ambient conditions and high temperatures; it can be installed in Ex areas
  • High level of functional dependability thanks to fully automatic sensing tube monitoring
  • High-performance software: ADW HeatCalc for planning, ADW Config for configuration and maintenance
  • EN 54-22 and UL/FM approved

 

ADW HeatCalc

ADW HeatCalc is an easy to use design tool that allows the designer to draw the proposed installation in isometric view on a PC.  The HeatCalc tool then calculates the programming criteria based upon the desired response temperatures.  The calculated values form part of the project report, which is used to programme the detector as part of the commissioning process.
