  • This chimney effect is exacerbated by the fact that on the vessel to be monitored, a metal-formed fireplace is placed, in which then the individually operated detector is arranged.
  • DE 615516 C already describes a known as MMS system arrangement of an electrical fire detection system with hotlines, which are connected for reasons of management economy by a common ring or loop line to a central office.
  • this solution has, inter alia, the disadvantage that in addition to the sensor always a power supply and an evaluation (in a housing) must be mounted on site, resulting in not only a large amount of space but also a higher cost, energy losses, or high effort decentralized battery monitoring and care results.

  • a key system disadvantage of RAS is the inaccurate indentifiability of the affected smoke aspiration bore through which the smoke particles enter.
  • RAS can not be used anywhere, eg not in vessels with small (size), tightly closed vessels, eg low-voltage or main distributions with a high degree of protection such as IP 65 and higher, because they do not allow air exchange to the outside, or in these usually the space is missing.
  • this solution works according to the basic principle of RAS, but tries in particular the disadvantage of not possible in principle localization of the affected Rauchansaugbohrung by a complicated sequence (flow reversal of the detection air after the first detection - blowing the tubes fresh air - re-aspiration of the detection air - measuring the Duration of the fire parameter up to the sensor - to calculate the position of the smoke aspiration bore - output of the alarm).
