Meross CS11 - Combo Smoke and Carbon Monoxide Alarm

Keep your home safe with our advanced 2-in-1 smoke and carbon monoxide detector. Combining a photoelectric smoke sensor with an electrochemical CO sensor, it detects both hazards independently, prioritizing smoke alerts first if both are present. Its sensitivity to fast- and slow-burning fires helps minimize false alarms.

Designed for convenience, the detector features a sleek, round white design that blends seamlessly into any home. A built-in 3V CR123A battery provides up to 10 years of reliable protection without the need for replacement. The alarm emits a loud 85dB+ sound at 3 meters and includes a test/silence button for easy monthly checks.

Equipped with a smart chipset, the detector activates automatically when mounted. A green LED indicates normal operation, while red signals an emergency. It meets EN 14604 and EN 50291 standards, ensuring top-quality performance.

Installation is quick and simple—battery-operated and requiring no wiring, it can be mounted on walls or ceilings in minutes using the included screws. For optimal CO detection, install approximately 30 cm from the ceiling, as carbon monoxide is lighter than air.
