Plug-In Digital Display Carbon Monoxide Alarm with Battery Backup

First Alert Plug-In Carbon Monoxide Alarm with Digital Display and Battery Backup

The First Alert FCD4CN-3 Plug-In Carbon Monoxide Alarm is a sophisticated life-safety device designed to provide continuous and accurate monitoring of carbon monoxide levels within your home. Known as the silent killer, carbon monoxide is a colorless, odorless, and tasteless gas that can be fatal if undetected. This AC-powered alarm plugs directly into any standard wall outlet, making installation as simple as possible. To ensure that your family remains protected during emergencies, the unit features a nine-volt alkaline battery backup, providing uninterrupted monitoring even during a total power failure. This dual-power reliability is essential for maintaining safety during storms or electrical grid issues when heating systems may be operating under stress.

One of the most advanced features of the FCD4CN-3 is its backlit digital display, which provides real-time information on CO concentrations in parts per million. The unit is equipped with a peak level memory function, allowing you to recall the highest level of carbon monoxide detected since the device was last reset. This is a critical diagnostic tool for emergency responders or HVAC technicians when investigating potential leaks. For added convenience, this model features First Alert's patented IR remote control technology. This unique system allows you to test the alarm's functions or silence a nuisance alert using almost any standard household TV or VCR remote control, eliminating the need to reach for the device if it is installed in an awkward or low-profile location.

This carbon monoxide detector is microprocessor-controlled, ensuring a high level of accuracy and a significant reduction in false alarms. It is fully compliant with the UL2034 standard for safety, which is the benchmark for residential CO detection. The unit’s compact design is engineered to occupy only one wall outlet, leaving the second socket free for other household electronics. In the event of a dangerous CO buildup, a powerful eighty-five-decibel horn will sound, providing a clear and urgent warning to all occupants. For maximum safety, experts recommend installing a CO alarm on every level of the home and in every sleeping area. Backed by a five-year limited warranty, the First Alert FCD4CN-3 offers professional-grade protection and peace of mind for you and your loved ones.
