The Kidde i12010SCO is a hardwired combination smoke and CO alarm with 10-year sealed 3V lithium battery backup. Intelligent sensor technology combines ionization smoke sensing with electrochemical CO detection — the sensors communicate to offer fast response to real fires (both smoldering and fast-flaming) while reducing nuisance alarms. Sealed 3V lithium battery eliminates battery replacement for the alarm's 10-year life. Voice warning announces 'Fire!' or 'Warning, Carbon Monoxide.' A single Test/Hush button verifies circuitry and silences nuisance alarms. Interconnects with other Kidde hardwired alarms.
Does the i12010SCO require battery maintenance?
No. The 10-year sealed 3V lithium battery backup is built-in and tamper-proof — it cannot be removed or replaced. It provides backup power throughout the alarm's 10-year service life. At end of life, the alarm chirps to signal replacement of the entire unit.
What is listed as a replacement for the i12010SCO?
Kidde cross-references the i12010SCO as a predecessor to the 30CUA10 (DETECT hardwired combo with 10-year battery). The replacement guide at kidde.com/support/smoke-alarms/alarm-replacement-guide provides the latest cross-reference.
