How often do I need to replace batteries in the 30CUDR?
Kidde recommends changing the 2 AA batteries every 6 months, or when you hear the low battery chirp. The alarm will beep and blink red to alert you when batteries are low.
Does the 30CUDR interconnect with other alarms?
No. The 30CUDR is a standalone battery-powered alarm and does not support interconnect. If you need whole-home interconnected alarms, consider the hardwired DETECT models (30CUAR or 30CUA10) which interconnect when one alarm sounds.
