Gas Detector Brennenstuhl CM A 3030 Carbon Monoxide CO Electrochemical 85 dB

The Brennenstuhl CM A 3030 is a battery-powered electrochemical carbon monoxide (CO) detector designed to protect indoor spaces where fuel-burning appliances are used or where people spend extended periods, such as living rooms and bedrooms. The compact, surface-mounted unit monitors invisible and odourless CO and gives a clear alert when dangerous levels are detected. It comes with two AA 1.5V lithium batteries and features an LED display for status indication.

Advantages

The detector provides a penetrating 85 dB alarm and uses an electrochemical sensor for reliable CO detection. It signals low battery with both optical and acoustic alerts, has a compact surface-mounted design (120 mm × 37 mm × 80 mm) and operates on readily available AA lithium batteries. The unit is suitable for continuous indoor monitoring and easy installation on walls or ceilings.

Suitable for

• Homes with gas boilers or oil heating
• Rooms with fireplaces or other fuel-burning appliances
• Living rooms and bedrooms where people spend long periods
• Any indoor area requiring continuous CO monitoring

Place detectors near fuel-burning appliances and in living or sleeping areas but avoid locations directly above stoves or close to ventilation outlets. If the alarm sounds, evacuate the premises immediately and ventilate where safe; seek fresh air and contact emergency services if symptoms of CO exposure are present.

Recommendations

The detector should be installed in every room with fuel-operated appliances and in living areas. Test the device regularly, replace batteries as indicated by low-battery signals, and replace the unit according to the manufacturer’s recommended service life to ensure reliable protection against carbon monoxide.
