EURA CSD-39A2 Carbon Monoxide and Smoke Detector

The EURA CSD-39A2 is a dual-function carbon monoxide (CO) and smoke detector designed for reliable home safety. Combining electrochemical CO sensing with photoelectric smoke detection, this device provides comprehensive protection against two of the most common household hazards. Powered by 3x AA batteries with a long battery life of approximately 3 years, it offers wireless installation on walls or ceilings. The clear LCD display shows real-time CO concentration, while audible and visual alarms alert you to danger. Certified to EN 50291-1:2018 for CO and EN 14604:2005/AC:2008 for smoke, the CSD-39A2 is a trustworthy choice for safeguarding your family.

Advantages

Dual detection covers both CO and smoke, eliminating the need for separate units. The electrochemical CO sensor provides accurate readings, while the photoelectric smoke sensor reduces false alarms from cooking. Easy battery-powered installation means no wiring required, and the self-diagnosis function ensures the detector is always working properly. The end-of-life indicator reminds you when to replace the unit, and the low battery warning prevents unexpected downtime.

Suitable for

• Home bedrooms, hallways, and living areas
• Apartments and small offices
• Cabins, RVs, and other spaces without hardwired alarms
• Anyone seeking an all-in-one CO and smoke detector
