Kidde Smoke & Carbon Monoxide Detector, AA Battery Powered, Voice Alerts, LED Warning Light Indicators, 30CUDR-V

2-IN-1 DETECTION: Alerts you to both smoke and carbon monoxide (CO) using a single detector.
ENHANCED SENSING TECHNOLOGY: Reduces false smoke alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition, UL 2034 4th Edition, and FCC standards.
NO WIRING NEEDED: Operates on 2-AA alkaline batteries (included) providing easy installation, simply mount the bracket onto the ceiling and twist and click the 5-inch smoke and CO alarm into the bracket.
VOICE ALERTS: Crystal-clear voice alerts will say "Fire." when smoke is detected or "Warning. Carbon Monoxide." if CO is detected, so you can react quickly.
SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.
3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke or carbon monoxide detected and a loud 85-decibel alarm will sound.
TEST and HUSH BUTTON: Makes it easy to test the 5-inch combination detector and silence false alarms, should they occur.
10-YEAR LIMITED WARRANTY: Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced.
