The Kidde DETECT 21031451 photoelectric smoke detector uses optical technology to preferentially detect smoldering fires—smoldering fires, electrical overheating, nighttime fires—which represent the most dangerous situations. Certified to ULC S531 (Canadian standard), it generates fewer false alarms than ionization models during cooking.
