The Kidde P3010CU is a 10-year sealed battery combination smoke and CO alarm with voice warning and Smart Hush feature. It uses photoelectric and electrochemical sensing technology where both sensors communicate — when either detects a hazard, it alerts the other for faster real-fire detection and reduced nuisance alarms. Voice alerts announce the hazard type. A single Test/Hush button tests circuitry and silences nuisance alarms. A flashing red LED indicator shows alarm status. No battery changes for 10 years. This model is replaced by the 30CUD10-V.
What replaces the P3010CU?
Kidde recommends upgrading to the 30CUD10-V, the current DETECT line 10-year battery combo alarm with voice alerts, enhanced sensing technology, self-testing, and updated UL 217 10th Edition certification.
Does the P3010CU need a battery replacement?
No. The 10-year sealed lithium battery is built-in and provides maintenance-free operation for the full 10-year service life. At end of life, the unit chirps to signal replacement.
