About this item 

• 2-IN-1 DETECTION: Alerts you to both smoke & carbon monoxide (CO) using a single, cost-effective 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, & FCC standards. 
• NO WIRING NEEDED: Operates on 2-AA alkaline batteries (included) providing easy installation, simply mount the bracket onto the ceiling and twist & click the 5-inch smoke & CO alarm into the bracket. 
• 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 & a loud 85-decibel alarm will sound. 
• TEST & HUSH BUTTON: Makes it easy to test the 5-inch combination detector and silence false alarms, should they occur. 
• BATTERY REPLACEMENT: Batteries should be replaced every 6 months, a low battery chirp alerts you when batteries need replacing. 
• 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.
