1. A method for determining a triggering time for issuing an alarm of an alarm device, the method which comprises:

  • detecting a measured value at a measuring time, the measured value being indicative of a hazard potential within a monitoring range;

    establishing a waiting time by way of a function based on a given standard, the function;

    specifying an assigned waiting time in each case for a plurality of different measured values, the waiting time reducing as the measured value rises and increasing as the measured value falls, for a slight increase in the measured value, the corresponding waiting time also only changes slightly; and

    having a continuous profile, the continuous profile not exhibiting jumps or discontinuities;

    determining the triggering time based on the measuring time and the waiting time thus established; and

    the waiting time being the time necessary to wait after the occurrence of the measured value before an alarm may be issued; and

    covering extended alarm issuing ranges, the extended alarm issuing ranges resulting in the alarm being issued more quickly than if the alarm issuing conditions predetermined by the standard are used for issuing the alarm.
