A method for fire recognition is disclosed, serving to avoid false alarms, in which an alarm threshold is determined depending upon signal parameters received from at least one sensor signal. False alarms can thus be advantageously filtered out. The above is further improved by the establishment of an alarm interval, for which the alarm threshold must be exceeded, in order for an alarm to be recognised. Said alarm interval can also be adapted according to signal parameters. An upper and lower limit are set for both alarm interval and alarm threshold, in order to incorporate a certain security, such that the alarm interval and alarm threshold do not adopt values which would put a functioning of the fire alarm at risk. Several sensor signals may be used, whereby the signal parameters are then generated by linking the sensor signals. A light-scattering smoke detector, fitted with a labyrinth and a detector chamber is preferably used.
