Gas detector FireAngel FA3322-EUX10 — Carbon monoxide (CO) electrochemical, LCD, battery 3 V, ABS housing

The FireAngel FA3322-EUX10 is a digital carbon monoxide (CO) alarm with an electrochemical sensor and an LCD display. Designed for residential use, the device provides continuous CO monitoring, shows real-time CO concentration and temperature on the digital screen, and fits standard installations. The alarm runs on a 3 V battery and is housed in a durable ABS enclosure measuring 129 × 76 × 31 mm. It replaces end-of-life CO-9D models and carries BSI Kitemark approvals for reliable detection.

Advantages

The unit combines an electrochemical CO sensor with a multi‑functional LCD that displays CO levels, temperature in standby and visual user instructions. It includes low-level monitoring with a unique pre‑alarm ‘ventilate’ warning to prompt window opening at low concentrations, and the display changes colour to indicate different warnings and instructions. Multiple power input options ensure compatibility with a range of installations and reliable long-term operation.

Suitable for

• Home monitoring of carbon monoxide in living rooms and bedrooms
• Replacement of older CO-9D alarms in domestic settings
• Residential kitchens, boiler rooms and areas with gas appliances

How to use

Mount the alarm on a wall or other suitable location following the manufacturer’s installation guidance and local regulations, ensuring it is positioned where it can detect CO from fuel-burning appliances. Insert the 3 V battery and check the LCD to confirm power-on and sensor status. The display shows current CO concentration and temperature; follow the visual instructions and colour indicators on the screen if a warning or pre‑alarm appears. If the ventilate or alarm warning activates, ventilate the area immediately and follow safety procedures.

Recommendations

Install the detector in sleeping areas and near potential sources of CO, test regularly according to the manufacturer’s instructions, replace batteries as recommended, and replace the unit at end of life. If the alarm sounds, ventilate the area and avoid re-entry until the cause is identified and resolved.
