    Hardwired Smoke & Carbon Monoxide Detector, AA Battery Backup, Interconnectable, LED Warning Light Indicators, 4 Pack

    • 2-in-1 Detection - This combination smoke and carbon monoxide detector alerts you to both smoke and fire events as well as poisonous CO gas in a single unit. Continuous 24/7 self-testing components monitor the device to confirm it is functioning correctly (this does not replace a manual push test). Simple installation with the provided mounting bracket allows for quick setup in 4 different orientations. The photoelectric sensor identifies visible fire particles linked to slow, smoldering fires, while the electrochemical sensor identifies carbon monoxide. An 85-decibel alarm and LED warning indicators notify you of various statuses: green shows normal operation, amber shows an operating error, and red shows a smoke, fire, or carbon monoxide event. Battery powered for dependable detection, even during power outages; two AA batteries are included
