Detectors, a test device for testing of a detector and method for operating a detector

摘要

A method for operating a detector (1) for the detection of gas or smoke, in particular of a fire - detector, which detector (1) a sensor (2) for measuring the concentration of the interference medium, wherein the concentration levels - measuring signal (7) of the sensor (2) a filter operation for detecting a in the case of a the event of occurring interference medium - concentration pattern is subjected to, and wherein during the detection of this concentration pattern of the event of an alarm is recorded, characterized in that, in order to test the functionality of the detector (1) in the detection range of the sensor (2) interference medium with one of the occurring in the event of an alarm to medium - concentration patterns different interference medium - concentration patterns is emitted, is that the concentration levels - measuring signal (7) of the sensor (2) in addition to the first filter operation of a second filter operation for detecting the occurring in the test medium - concentration interference pattern is subjected to, and in that in the detection of this test - concentration pattern the occurrence of a typical is recorded.
