No battery changes for 10 years — it avoids inconvenient replacements and saves up to $40 over the device's life. Cutting-edge sensing technology delivers fast alerts, while enhanced sensing technology reduces false alarms often caused by cooking. Hardwired interconnect means when one alarm sounds, all connected alarms sound throughout the home. Self-testing components continuously verify the alarm is functioning. Simple installation with the included twist-and-click mounting bracket.
What models does the 30CUA10 replace?
The 30CUA10 is the current DETECT replacement for older Kidde hardwired combo alarms with 10-year sealed backup including the i12010SCO. It adds self-testing and DETECT enhanced sensing while maintaining the same hardwired 10-year sealed battery backup configuration.
Does the 30CUA10 need any battery maintenance?
No. The sealed 10-year lithium battery is built into the alarm and cannot be replaced. It provides backup power for the full 10-year service life of the alarm. At end of life, the alarm beeps to signal it is time to replace the entire unit.
