In reviews, experts consistently point to the First Alert Dual Sensor as the best smoke detector. It runs on a replaceable 9-volt battery and features a combination ionization and photoelectric sensor that is by far the… most accurate and effective detection method available. The SA302CN has extra features that many detectors do not, such as remote-controlled alarm silence and test, Intelligent Sensing, which differentiates non-threatening conditions (i.e. kitchen smoke) from real emergencies, and an automatic daily self-check test. This model has a 10-year warranty. One downside is that some owners say you can accidentally trigger the test function with your TV's remote control, so it may take some trial and error to get the right placement.
