This 2-in-1 smoke and carbon monoxide (CO) detector provides reliable protection with a single, cost-effective unit. It operates on 120V AC wiring (installed in the ceiling) and comes with 2 AA alkaline batteries for backup during power outages. Equipped with enhanced sensing technology, it minimizes false alarms often triggered by cooking, and is thoroughly tested to meet the latest UL standards (UL 217 9th Edition, UL 2034 4th Edition) as well as FCC requirements. The detector also features interconnect capability, so when one alarm sounds, all alarms in the system will sound, helping you evacuate faster.

Other useful features include a self-testing alarm that monitors internal components, ensuring the detector is always operating as expected. It’s recommended to perform a manual button test weekly to verify alarm functionality. The 3 LED notifications—green for normal operation, amber for errors, and red for smoke or CO detection—are accompanied by an 85-decibel alarm for added safety. The test and hush button allows you to easily test the detector or silence false alarms. Backed by a 10-year limited warranty, this detector offers peace of mind, with the warranty beginning when the alarm is powered on. If the activation date is unknown, it is recommended to replace the alarm after 10 years of use.
