Gas leak detector Qoltec 52576 — CO detector with 85 dB alarm, EN50291-1:2018 certified

Qoltec 52576 is a compact gas leak and carbon monoxide (CO) detector designed for residential and small commercial spaces. The device combines continuous monitoring of flammable gas and CO levels with an integrated 85 dB audible alarm and meets EN50291-1:2018 safety requirements. Its intended use is to provide early warning of dangerous gas or CO accumulation in homes, apartments, garages and similar enclosed areas.

Advantages

The unit offers dual-function detection of both combustible gases and carbon monoxide in a single compact housing, reducing the need for multiple sensors. An integrated 85 dB alarm provides a clear audible alert to occupants, while compliance with EN50291-1:2018 means the detector complies with recognized safety and performance standards. The design is suitable for wall- or ceiling-mounted installation and for continuous, unattended operation in living spaces.

Suitable for

• Homes and apartments where gas appliances are present
• Garages and utility rooms with fuel-burning equipment
• Small commercial premises such as offices or workshops
• Replacement or upgrade of older single-function detectors

When it may not be suitable

This detector is intended for residential and small commercial environments and may not be appropriate for industrial sites requiring specialist hazardous-area equipment or multi-sensor safety systems. It is not a substitute for proper ventilation, gas system maintenance or professional gas detection networks in larger facilities.

Key specifications

• Detections: carbon monoxide (CO) and combustible gas
• Audible alarm level: 85 dB
• Certification: complies with EN50291-1:2018 standard
• Power: battery or mains powered options (refer to product packaging for specific power type)
• Mounting: wall or ceiling installation

How to use

Install the detector according to the manufacturer’s mounting guidance at an appropriate location near potential gas sources but away from drafts or direct airflow. Power the unit as specified in the product instructions and perform the initial functional test after installation. The detector continuously monitors air and triggers the 85 dB alarm when preset thresholds for CO or combustible gas are exceeded. Regularly test the alarm, replace batteries or maintain power supply as required, and follow user manual instructions for end-of-life and sensor replacement indicators.

What to consider before purchase

• Whether combined CO and combustible gas detection meets the specific risks in your space
• Power supply preference (battery versus mains) and maintenance access for battery replacement
• Mounting location suitability and distance from gas appliances or vents
• Compliance with local regulations and whether EN50291-1:2018 certification is required

Usage recommendations

Place the detector in sleeping areas and rooms with fuel-burning appliances, test it regularly, and ensure occupants are familiar with the alarm sound and evacuation procedures. For enhanced safety, combine with regular appliance servicing and appropriate ventilation.
