SecuriSens ADW 511

SecuriSens ADW 511 Transafe - the linear heat detector

No limits to effective fire protection
The protection of people, assets and the environment becomes crucial whenever conventional fire protection methods are no longer adequate. Corrosive gases, extreme humidity, high temperatures and polluted air entail difficult operating conditions for reliable fire detection. The ADW 511 system is false alarm-proof and failsafe. Intelligent electronic signal evaluation means that fires are detected quickly and reliably. With continuous, fully automatic monitoring, maintenance work is reduced to a minimum. The ADW 511 meets the response behaviour according to EN 54-5, class A1, is VdS and UL approved and has obtained the Certificate of German Lloyds (offshore- and vessel applications). The system has been tried and tested world-wide in:

  • Road, railway and underground tunnels
  • Railway stations, passenger areas, connecting corridors
  • Locomotive and tramway depots
  • Underground car parks and semi-open multi-storey car parks
  • Warehouses for combustible gases and liquids
  • Fuel reloading stations and open loading ramps
  • Areas subject to explosion hazards
  • Mines and conveyor installations, drilling platforms and rigs
  • Chemical/pharmaceutical plants, painting plants

Mode of operation
Linear heat detectors are based on the physical principle that, for a given volume, the pressure of a gas changes whenever its temperature changes. Over a distance of approx. 100 m a copper sensor tube monitors the ambient temperature. A fire source will heat up the sensor tube locally and, with it, the air it contains. The change in pressure is instantly registered by an electronic pressure sensor connected to the extremity of the tube. To exclude faulty measurements due to pressure losses, a test motor generates a specific overpressure in the sensor tube at regular intervals. If the pressure rise actually measured does not correspond to the programmed measured value, a malfunction indication is displayed. The system is user-friendly, immune to electrical, thermal and mechanical interference, and can be used as a combined rate-of-rise temperature detector/fixed temperature heat detector.
