Kidde Firex Hard-Wired w/Battery Back-up Ionization Smoke Detector

The Kidde i5000 is an AC/DC powered, ionization smoke alarm that operates on a 120V power source with 9V alkaline battery backup. This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization 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.Front battery pull tab allows battery activation without removing alarm from mounting bracket.Large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections.Pre-stripped wiring harness with easy off cap does not require stripper tool.
