First Alert CO615 Dual-Power Plug-In CO Detector with Battery Backup and Digital Display

Dual-Power CO615 for peace of mind

The First Alert CO615 carbon monoxide detector combines plug-in convenience with a reliable battery backup, ensuring continuous monitoring even during power outages. A backlit digital display lets you see current CO levels at a glance, while the unit’s simple test and silence controls make routine checks quick and straightforward.

Powered by a dual system, the CO615 stays alert where you live and sleep, and its compact design fits standard outlets without obstructing other devices. The display shows CO concentrations in parts per million (ppm) and confirms power status with a brief display light when power is present. This combination of visibility and reliability helps you monitor your indoor air with minimal effort.

Smart sensing and clear alerts

• Electrochemical sensor: Uses industry-standard technology to detect CO levels accurately and consistently.
• Peak level feature: Highlights the highest CO concentration measured for quick assessment over time.

In addition to accurate readings, the CO615 provides a loud 85-decibel alarm to signal dangerous levels, accompanied by a visual alert when the battery is low or removed. An end-of-life chirp warns you when it’s time to replace the unit, helping you maintain protection over the years.

Safety features you can rely on

• Battery backup: Ensures monitoring continues during outages, while the primary AC power keeps the display active.
• Test/Silence button: Quickly checks functionality or silences non-emergency alerts.
• Low battery indicators: Audible and visual cues prompt timely battery replacement.
• UL listed and backed by a 7-year limited warranty for added assurance.

Placement and use: For comprehensive protection, place detectors on each level of your home and in bedrooms where you spend time. The CO615 is simple to install by plugging into any standard wall outlet, and it ships with batteries and a user’s manual for setup guidance.

Note: The unit’s battery is for backup only and does not power the alarm long-term without AC power. The display briefly lights to indicate power if connected, and the test button confirms activation. This detector helps you stay informed about potential CO in your living spaces without making guarantees about outcomes.
