Not all fires are alike. Some fires, like kitchen fires create fast flames and are detected best by the ionization technology. Other fires like cigarettes can smolder in a couch for several hours before erupting into flames. In these cases, residents can die from smoke inhalation before flames ever break out. The photoelectric sensor does the best job in detecting smoldering fires. The First Alert SA320CN Double Battery Powered smoke detector has a loud alarm so it can be heard throughout the house and responded to quickly.
