During normal operation, the green LED light will be steadily illuminated for hardwired alarms. For battery-operated models (if applicable), a flashing green LED light every 60 seconds indicates normal operation.

Detección de humo

When smoke is detected, the alarm will sound a loud 85-decibel alarm (3 long beeps) with the red LED light flashing in time, repeating. The enhanced sensing technology helps reduce false alarms from cooking.
