If the carbon-monoxide-detector detects both smoke and carbon monoxide, it sounds first for smoke and then for CO. The CO detector detects both fast and slow-burning fires, minimising false alarms. - 10-Year Service Life: The smoke alarm and carbon monoxide detector contains one built-in 3V CR123A battery (not removable) that can last 10 years. You can avoid the trouble of replacing the battery, and it ensures your carbon monoxide alarm is always ready to protect. - User-Friendly Design: The light and simple white round design ensures the carbon monoxide detector blends seamlessly into your home. The carbon monoxide and smoke detector includes a test/silence button (please press the test button monthly to confirm the working status of the smoke alarm). The fire alarm sound is over 85dB at 3 metres and sounds throughout your home; press the test button to silence. - High-Tech: This carbon monoxide and smoke detector has an inbuilt smart chipset. The carbon monoxide alarm is automatically activated when it is attached to the bracket. The LED light is normally green and turns red in an emergency. The smoke alarm for home complies with EN 14604 and EN 50291 standards to ensure reliable quality. - Easy Installation: The battery-operated smoke detector (not wired) can be installed by yourself in 5 minutes without the need for an electrician. The CO alarm is easy to mount on any wall or ceiling with the included screws. Note: Carbon monoxide is lighter than air, so it is recommended to install it at a distance of 30 cm from the ceiling. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5XH6FJY | | Best Sellers Rank | 42,065 in DIY & Tools ( See Top 100 in DIY & Tools ) 12 in Combination Smoke & Carbon Monoxide Detectors | | Brand | meross | | Colour | White | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 76 Reviews | | Included Components | 1 x Combination Smoke and Carbon Monoxide Detectors 1 x Mounting Bracket 1 x Screw Kit 1 x User Manual | | Item Dimensions D x W x H | 2.8D x 12W x 12H centimetres | | Item Type Name | Smart Smoke Alarm | | Item Weight | 135 Grams | | Item weight | 135 Grams | | Manufacturer | meross | | Model Number | CS11 | | Number of Items | 1 | | Part Number | CS11 | | Power source | Battery Powered | | Product Style | Smoke & CO Detector | | Product dimensions | 2.8D x 12W x 12H centimetres | | Style | Smoke & CO Detector | | Unit Count | 1.0 count | ## Product Details - **Brand:** meross - **Colour:** White - **Item weight:** 135 Grams - **Manufacturer:** meross - **Number of items:** 1 - **Power source:** Battery Powered - **Product dimensions:** 2.8D x 12W x 12H centimetres - **Style:** Smoke & CO Detector - **Unit count:** 1.0 count ## Images ![Meross CS11 Dual Sensor Smoke and Carbon Monoxide Alarm/Detector for Home - Image 1](https://m.media-amazon.com/images/I/61AOrhOOnUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install *by R***S on 27 April 2026* Easy to install.

Its slimline design (very neat!) means it can be tricky placing the alarm into its holder. Too early to really give proper feedback, although I was hoping for this to be "smart" (as most things from meross tend to be). I haven't noticed the light that flashes regularly to indicate that the detector is working, which is good or bad depending on your take. ## Frequently Bought Together - meross CS11 Safty Alarm, White, 1 Pack - Meross Interlinked WiFi Smoke Alarm, Smoke Detector with Hub, Low Battery Alert Silence Button, Wireless Smoke Alarms for Home, Replaceable Battery, Apple HomeKit, SmartThings Supported, 2.4GHz Only --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/659824221-meross-cs11-dual-sensor-smoke-and-carbon-monoxide-alarm-detector](https://www.desertcart.tn/products/659824221-meross-cs11-dual-sensor-smoke-and-carbon-monoxide-alarm-detector) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-14*
