- Abstract
- [ABSTRACT IN ENGLISH] By sorting operation density, two models each of ionization and photoelectric type detectors were evaluated. Fisher's official linear law was used to calculate the trigger rate. Differences in both the detector type and model were noted when tested in kitchens and cafeterias. Use and position of a ventilation fan also influenced whether the detector was triggered.
