False Alarm Immunity - GasTech F-Guard-IR3-H2 User Manual

False Alarm Immunity

The following table shows test results of false alarm immunity for detectors configured to "Extreme"
sensitivity. For each radiation source a distance is listed. This is the minimum tested distance, from which the
detectors did not alarm when exposed to the radiation source (either modulated or non-modulated).
