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.
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.
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.
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.)
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.
2-IN-1 DETECTION: Alerts you to both smoke & carbon monoxide (CO) using a single, cost-effective device.
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.)
Voice alerts are clear and will announce "Fire!" when smoke is detected or "Warning! Carbon Monoxide!" if CO is detected, enabling prompt responses.
