- Abstract
- [ABSTRACT IN ENGLISH] A discussion of using particle make-up to prevent false alarms. By shining a multi-wave length light through particles, find extinction coefficients. Compare the extinction coefficients and determine the particle. Extinction multiplier ratio varies according to smoke particle type. If the ratio falls within a certain range, fire and false alarms can be differentiated.
