Meross CS11-EU smoke and carbon monoxide detector
Meross CS11-EU is a compact yet highly effective sensor equipped with two independent sensors – photoelectric for smoke detection and electrochemical for CO monitoring. Such a solution guarantees a quick response to an emergency! At the same time, the device is small and unobtrusive, and its built-in CR123A battery provides a long operating time – up to about 10 years.
Immediate response to danger
The sensor meets EN14604 and EN50291 standards, which confirms its effectiveness and quality of operation. The device responds automatically when CO levels reach dangerous values – for example, at a concentration of 300 ppm the alarm sounds in less than 3 minutes. A loud signal of more than 85 dB guarantees that the device will be heard even by sleeping household members.
Reliability and precision
If the sensor detects both smoke and carbon monoxide, it will first beep for smoke and then for CO. What’s more, the device detects both fast and slow-burning fires, minimizing false alarms.
Simple installation without cables
The detector is powered by a built-in 3V CR123A battery with a lifespan of up to 10 years. This, combined with its clever design, makes its installation take no more than a few minutes and does not require the help of an electrician. All you have to do is screw the mounting bracket to the ceiling or wall, then place the device in it – and you’re done!
Intuitive light signaling
Meross CS11-EU is equipped with a three-color LED that clearly communicates the status of the device. A green light indicates readiness for operation, an amber light indicates a low battery or fault, and a red light indicates alarm activation or test mode. Operation of the sensor is extremely simple – just press one button to perform a test or silence the alarm.
Thoughtful design and discretion
The slim, white housing with a round shape makes the sensor blend in perfectly with any interior. Thanks to its compact size, it is unobtrusive while effectively protecting you and your loved ones from an invisible threat.
