The Kidde 30CUAR is a hardwired combination smoke and CO alarm from the DETECT line with 2 AA replaceable battery backup. Cutting-edge sensing technology delivers fast alerts to give families more time to evacuate, 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. Change backup batteries every 6 months or when you hear the low battery chirp.
What models does the 30CUAR replace?
The 30CUAR is the current DETECT replacement for older Kidde hardwired combo alarms with AA backup including the 900-CUAR and KN-COSM-IBA. It adds self-testing and DETECT enhanced sensing technology while maintaining the same hardwired AA backup configuration.
How does interconnect work on the 30CUAR?
The 30CUAR uses hardwired interconnect — it connects to other Kidde hardwired alarms via the existing wiring. When any one alarm detects smoke or CO, all interconnected alarms in the home sound simultaneously, giving occupants in other rooms maximum warning time.
