Carbon monoxide sensor CO detector QOLTEC EB503554399 — 85 dB alarm, LED indicators, certified

QOLTEC carbon monoxide sensor EB503554399 is a certified CO detector designed for continuous monitoring of indoor air to identify dangerous concentrations of carbon monoxide. The device combines an electrochemical sensing element with visual LED indicators and an 85 dB audible alarm to ensure timely notification when CO levels rise. Compact and intended for domestic and small commercial environments, the detector assists in early warning near boilers, gas appliances, garages and sleeping areas.

Advantages

The detector provides reliable CO detection using a sensor technology that responds to low and elevated carbon monoxide concentrations. LED indicators offer clear visual status feedback for normal operation, fault conditions and alarm states, while the 85 dB alarm delivers an audible alert loud enough to wake occupants. The unit is certified for safety and performance, designed for straightforward installation and continuous operation with minimal maintenance.

Suitable for

• Homes and apartments — monitoring sleeping areas and living spaces
• Boiler rooms and areas near gas-fired appliances
• Garages and workshops where combustion engines run
• Small commercial premises such as offices, retail or service rooms

Key specifications

• Detection target: carbon monoxide (CO)
• Audible alarm level: 85 dB
• Visual indicators: multi-color LEDs for status and alarm
• Sensor type: electrochemical CO sensor (certified performance)
• Operation: continuous monitoring with automatic alarm
• Typical mounting: wall or ceiling installation in indoor spaces

How to use

Mount the detector according to manufacturer spacing recommendations, typically on a wall at breathing height or on a ceiling in the central part of the room. Ensure it is placed away from direct drafts, vents and areas of excessive moisture or dust. Power the unit as specified by the manufacturer and perform the initial functional check to confirm LED status indicators and the audible alarm work properly. Regularly test the device using the built-in test function and replace or service the sensor when indicated by the unit or according to the maintenance schedule.

Usage recommendations

Install one detector on every level of a building and at least one near sleeping areas. Avoid placing the detector directly above fuel-burning appliances or in very humid locations. If the alarm sounds, ventilate the area immediately, evacuate occupants, and seek fresh air; contact emergency services if symptoms of CO poisoning are present.
