Description
Meross CS11-EU Smoke and Carbon Monoxide Detector
The Meross CS11-EU is a compact yet highly effective detector featuring two independent sensors: a photoelectric one for smoke detection and an electrochemical one for carbon monoxide monitoring. This solution ensures a rapid response in an emergency! At the same time, the device is small and discreet, and the built-in CR123A battery offers a long battery life of up to approximately 10 years.

Immediate response to danger
The sensor complies with EN14604 and EN50291 standards, confirming its effectiveness and quality of operation. The device activates automatically when CO levels reach dangerous levels: for example, at a concentration of 300 ppm, the alarm goes off in less than 3 minutes. An audible signal of over 85 dB ensures the device is audible even to sleeping family members.

Reliability and precision
If the sensor detects both smoke and carbon monoxide, it will sound an alarm first for smoke and then for CO. Additionally, the device detects both fast-burning and slow-burning fires, minimizing false alarms.

Easy installation without cables
The detector is powered by a built-in 3V CR123A battery with a life of up to 10 years. This feature, combined with its intelligent design, makes installation a breeze and doesn't require an electrician. Simply screw the mounting bracket to the ceiling or wall, position the device, and you're done!

Intuitive light signaling
The Meross CS11-EU sensor features a tricolor LED that clearly communicates the device's status. A green light indicates readiness, an amber light indicates low battery or a fault, and a red light indicates alarm activation or test mode. Operating the sensor is extremely simple: simply press a button to perform a test or deactivate the alarm.

Careful design and discretion
The slim, white, round casing allows the sensor to blend seamlessly into any environment. Its compact size makes it discreet while effectively protecting you and your loved ones from an invisible threat.
