Photoelectric smoke sensor - may detect visible fire particles associated with slow smoldering fires sooner than an ionization sensor
AC wire-in with battery backup - powered by home's electricity in order to provide continuous protection; an included 9-volt battery protects during short-term power outages
Peak level memory - alerts user when unit has detected CO concentrations of 100ppm or higher
Smart touch button - 1-button performs multiple functions; unique battery door design - will not close if battery is not installed properly
