The Kidde P3010K-CA Worry-Free Talking Smoke Alarm is powered by a sealed, long-life lithium battery that lasts for ten years (the life of the alarm). It has a Hush button to temporarily silence nuisance alarms and there’s no battery to replace for the life of the alarm (10 years).
This alarm uses photoelectric sensing technology for the smoke alarm. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.
