2-IN-1 DETECTION: Alerts you to both smoke & carbon monoxide (CO) using a single, cost-effective device.
HARDWIRED & 10-YEAR BATTERY BACKUP: Operates on 120V AC wiring (installed in the ceiling). No battery changes for 10 years & saves up to $40 over the life of the 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.
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.
INTERCONNECT CAPABILITY: When one alarm sounds, they all sound, so you can get out faster. (Different models offer different interconnection options and requirements. See User Guide for more info.)
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.
10-YEAR WARRANTY: Begins when alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced. (10-yr limited warranty on alarm, not a battery performance claim.)
