Use and Care Manual
Worry-Free 120V AC Wire-in Smoke Alarm
Sealed Lithium Battery Backup
Model i12010S  
Description
The Kidde i12010S is an AC/DC powered, ionization 
smoke alarm that operates on a 120V power source with 
sealed-in lithium 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. 
Leading authorities recommend that both ionization 
and photoelectric smoke alarms be installed to help 
insure maximum detection of the various types of 
fires that can occur within the home. 
The i12010S contains a 10-year tamper proof battery 
that eliminates the need for battery replacement, and 
ends worry over unauthorized battery removal. The alarm 
provides continuous protection from smoke and fire, even 
during power outages. At the end of alarm life, the unit 
will chirp, indicating the alarm is in need of replacement. 
The customer can use a simple tool such as a screwdriver 
to deactivate the unit, stopping the chirp and making it 
safe for disposal. The end of life signal can be temporarily 
silenced to allow for replacement at a more convenient 
time.
