  • Known thermal hazard detectors include at least one temperature sensor for detecting a temperature within a monitoring range.
  • the temperature sensor In order to ensure a fast response and thus meet the commercial standards EN54-5, UL521 and FM3210, the temperature sensor should be as free from surrounding thermal mass as possible.
  • thermal decoupling between the temperature sensor and adjacent thermal masses is limited in practice.
  • a spatial separation between the temperature sensor and adjacent thermal masses would require a relatively large cavity within a thermal hazard alarm.
  • this cavity should be well flowed through by the ambient air.
  • the temperature sensor should be located in the middle of the cavity.
  • a large cavity is not available due to space problems in the rule.
  • the effective space requirement of such a hazard detector would be very large. This would be unsatisfactory also from an aesthetic point of view.
  • thermal hazard alarm In order to improve the response of a thermal hazard alarm, it is also known to condition the primary temperature measurement signal of a temperature sensor with a view to a faster signal rise with larger temperature changes. As is known, this can be done in an evaluation logic of a thermal hazard alarm.
  • the evaluation logic often includes a thermal model of the temperature sensor and / or the housing of the danger detector. By an appropriate procedure involving inversion of this thermal model, the signal evaluation can be improved for faster response. In this case, a so-called.

Despite this increase in limitation, however, the evaluation signal 292 has an overshoot, which briefly rises above an alarm threshold 295 at about 90 s after the beginning of the abrupt temperature change and thus triggers a false alarm.
  • Reference numeral 293 is the temporal behavior of the evaluation signal virtual_temp in the FIG. 1 shown evaluation device 110 shown. It can be seen very nicely that the signal 293 as well as the evaluation signal 293 rises steeply. Thus, in the case of a thermally displayed danger situation as well as a timely alarm is possible. In addition, an overshoot is advantageously avoided in the signal 293 and the evaluation signal 293 is always sufficiently far from the alarm limit 295. Thus, an undesirable false alarm can be reliably avoided.
