Detector de monóxido de carbono Alecto COA3910 — sensor CO electroquímico, a pilas, blanco, 110×78×37 mm

Alecto COA3910 is a battery-powered carbon monoxide detector designed for residential indoor use. The device uses an electrochemical CO sensor to monitor air for dangerous carbon monoxide levels and provides clear visual feedback with LED indicators that show status and battery level. Its compact white plastic housing (110×78×37 mm) allows flexible placement in living rooms, bedrooms and kitchens where CO accumulation is a risk.

Advantages

The electrochemical sensor offers accurate detection of low concentrations of carbon monoxide and stable performance over time. Battery power enables installation without wiring and allows placement where mains power is not available. The compact footprint and neutral white design integrate easily into home interiors. LED status indicators make it simple to check device condition and battery level at a glance.

Suitable for

• Homes with fuel-burning appliances (boilers, stoves, fireplaces)
• Apartments and rented accommodation where permanent wiring is not practical
• Bedrooms and living areas to warn occupants of CO buildup
• Kitchens and utility rooms near gas appliances

Key specifications

• Detection principle: electrochemical carbon monoxide sensor
• Power supply: battery-powered (replaceable batteries)
• Housing: white plastic
• Dimensions: 110 × 78 × 37 mm
• Visual indicators: LED status and battery level indicators
• Intended use: indoor residential CO monitoring

How to use

Mount the detector on a wall or place it on a stable surface at breathing height in the room to be monitored, avoiding enclosed corners and areas very close to windows or direct drafts. Insert the recommended batteries and check the LED indicators for normal operation and battery level. Test the unit according to the manufacturer's test procedure after installation and periodically thereafter to ensure the sensor and alarm circuits function correctly.

Recommendations

Install at least one carbon monoxide detector on each level of the home and close to sleeping areas. Replace batteries as indicated by the battery status LED or at regular intervals, and follow local guidance on detector placement and maintenance. Do not place the detector directly above fuel-burning appliances or in areas with high humidity or heavy dust accumulation, which can affect sensor performance.
