    • A method for detecting fires is proposed that serves to avoid false alarms, by providing that an alarm threshold is determined as a function of signal parameters derived from at least one sensor signal. False alarms are thus advantageously precluded. This is still further improved by setting up an alarm interval for which the alarm threshold must be exceeded, if an alarm is to be indicated. The alarm interval can also be determined adaptively as a function of the signal parameters. An upper threshold and a lower threshold are provided for the alarm interval and the alarm threshold, respectively, in order to build in a certain safety, so that the alarm threshold and alarm interval will not assume values that put a function of the fire detector at risk. It is also possible to use more sensor signals, in which case signal parameters can be generated by linking the sensor signals. As the fire detector, a scattered light smoke detector is preferably used, which is equipped with a labyrinth and a measurement chamber.
    • 提出了一种用于检测火灾的方法,其用于通过提供根据从至少一个传感器信号导出的信号参数的函数来确定报警阈值来避免误报。 因此有利地排除了虚假警报。 如果要指示报警,则通过设置必须超过报警阈值的报警间隔进一步改进。 报警间隔也可以根据信号参数自适应地确定。 分别为报警间隔和报警阈值提供上限阈值和下限阈值,以建立一定的安全性,使报警阈值和报警时间间隔不会置于将火灾探测器的功能置于 风险。 还可以使用更多的传感器信号,在这种情况下,可以通过连接传感器信号来产生信号参数。 作为火灾检测器,优选使用散射光检测器,其配备有迷宫式和测量室。
