Description

Protect your family and guests with the FireAngel FA3820 Carbon Monoxide Detector, a reliable CO alarm designed for home, holiday homes and travel. The unit uses an advanced electrochemical sensor that instantly detects dangerous carbon monoxide levels and sounds four loud chirps at 85 dB, while a flashing red LED provides a clear visual cue. For added safety, the detector features a high-sensitivity mode that predicts when CO concentrations may rise to 180 ppm or more, issuing a pre-alarm and a bright "ventilate" reminder so you can act before the gas becomes harmful. A sealed, tamper-proof 10-year battery powers the alarm for its entire life, removing the hassle of regular battery replacements and guaranteeing uninterrupted protection year after year. Its compact white housing blends discreetly with any decor, and the portable design means you can move it from room to room or pack it for vacations, cabins, and other off-site stays. Installation is simple - just mount the detector on a wall or place it on a flat surface, and the intuitive LED indicator will show status at a glance. With FireAngel's trusted technology, you gain peace of mind knowing that dangerous carbon monoxide is detected early and communicated loudly and clearly.

Key Features

Advanced electrochemical sensor quickly detects dangerous CO levels and triggers four loud chirps (85 dB) plus flashing red LED, giving immediate audible and visual warning.

High-sensitivity mode predicts CO rise to 180 ppm or higher, issuing a pre-alarm with a clear "ventilate" reminder so you can act before levels become hazardous.

Compact, portable design lets you place the detector in any room, take it on holiday trips, or keep it in a cabin, providing continuous CO monitoring wherever you go.

Simple white finish blends with home decor while the intuitive LED indicator and loud alarm make it easy for anyone to understand the device's status at a glance.
