Kidde Dual Sensor Smoke Alarm DC
The Kidde dual sensor smoke alarm uses both photoelectric and ionization to easily detect either a fast-flaming fire, or a slow smoldering fire.
The Kidde PI9000 smoke alarm features a blinking LED light to show it is functioning properly. It also has a low-battery warning.
With both the photoelectric and ionization technologies in use most fires will be noticed before real damage can be done.
