Photoelectric smoke detectors can detect slow, smoldering smoke the fastest, like the thick smoke when a couch or mattress is one fire. In comparison to smoke detectors using ionization technology, photoelectric smoke detectors set off an alarm earlier on slow burning materials. It can detect smoke faster in a large area or in a room with a high ceiling or rooms subject to temperature extremes. On the other hand the ionization type smoke detector is more sensitive to flames than to smoke. It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood.
