First Alert CO600 Plug-In Carbon Monoxide Detector – 3-Pack, White

Flexible plug-in protection for every level

The First Alert CO600 3-pack delivers practical carbon monoxide monitoring without mounting. Each detector plugs into a standard outlet, so you can quickly expand coverage across rooms and levels. An electrochemical sensor helps detect CO more reliably in different positions within a space, and when CO is detected, an 85-decibel alarm provides a clear, immediate warning.

• Place one detector on each level and in bedrooms for broad room-to-room awareness
• Clean, white design that blends with most home décors while remaining highly visible during alerts

Everyday usability and safety reminders

Beyond simple plug-in setup, this trio includes an end-of-life signal to indicate when replacement is needed. The single button silences nuisance alarms and runs a quick detector self-check, helping you confirm readiness without complex steps.

• End-of-life indicator supports proactive replacement planning
• One-button control for silencing and testing enhances ease of use

All units undergo UL-standard testing for consistent performance. Using multiple detectors in a home creates a straightforward safety network that can provide audible alerts across living spaces, with a simple way to monitor CO risk in real time.

Placement tips: avoid direct drafts or proximity to ignition sources, and refrain from using water, cleaners, or solvents near the unit, as they may damage it. Since these are plug-in devices, there is no wiring required, allowing you to adapt placement as your home evolves.
