The Kidde i12010S is a 120V AC hardwired interconnect ionization smoke alarm with a 10-year sealed lithium battery backup, eliminating battery replacements for the life of the alarm. The Hush button silences nuisance alarms and an alarm memory indicator identifies the initiating unit in an interconnected system. No surprise late-night low-battery chirps — the sealed battery lasts 10 years. This model has been replaced by the Kidde 20SA10.
Does the i12010S battery backup ever need replacement?
No. The i12010S has a 10-year sealed lithium battery backup that lasts the life of the alarm without replacement. At the end of 10 years, the alarm will indicate it is time to replace the entire unit.
Does the i12010S support hardwired interconnect?
Yes. The i12010S supports hardwired interconnect with up to 24 compatible Kidde devices. When any alarm in the chain detects smoke, all interconnected alarms sound simultaneously.
What does the alarm memory indicator do on the i12010S?
The alarm memory indicator flashes the LED on the unit that first triggered an alarm event. This helps identify which alarm in an interconnected system was the initiating device for troubleshooting.
Does the i12010S have a Hush feature?
Yes. The Hush button on the i12010S temporarily silences the alarm during nuisance events. The alarm will automatically reset after a few minutes if smoke levels return to normal.
What model replaced the i12010S?
The i12010S has been replaced by the Kidde 20SA10, part of the DETECT line with enhanced photoelectric sensing, hardwired interconnect, and a 10-year sealed battery backup.
