A smoke detection method includes ramp-counting of non-decreasing smoke level samples for detecting smoldering fire conditions and counting of obscuring smoke level samples for detecting other-than-smoldering fire conditions. The ramp-counting of non-decreasing smoke level samples includes increasing a smoke detection ramp count for each successive smoke level sample that does not decrease from a previous one and resetting the smoke detection ramp count whenever a smoke level sample decreases relative to a previous one.
