Product description: Battery-powered carbon monoxide detector - WiFi Tuya - Qoltec 52655
Qoltec Wireless Carbon Monoxide Detector Designed to continuously monitor indoor carbon monoxide concentrations , the electrochemical sensor ensures high measurement accuracy, and the LCD display provides current CO level readings ranging from 0 ppm to 999 ppm . If a threat is detected, the device triggers an audible alarm of at least 85 dB , displays an LED indicator , and sends a notification to your smartphone . 2.4 GHz WiFi connectivity allows you to connect the sensor to the Tuya Smart or Smart Life app, allowing you to check the device's status even when away from home. A self-diagnostic function checks the sensor and internal circuitry, while the TEST button allows you to independently test the alarm. The sensor can be wall-mounted using screws or double-sided tape, or placed on a stable, flat surface.

The wireless carbon monoxide sensor is suitable for rooms containing furnaces, boilers, fireplaces, water heaters or other fuel-burning appliances.
Main features of the Qoltec 52655 CO sensor
- Electrochemical CO sensor : precisely detects dangerous carbon monoxide concentrations and ensures stable operation
- Sensor lifespan up to 10 years : at the end of its service life, the device reminds you to replace the sensor
- LCD display : shows the current carbon monoxide concentration ranging from 0 ppm to 999 ppm
- Alarm with a minimum intensity of 85 dB : a loud signal helps to quickly warn people in the room
- LED light indicator : red LED provides additional information about detected threats
- Mobile notifications : the Tuya Smart or Smart Life app informs you about the alarm even when you are outside your home
- 2.4 GHz WiFi connectivity : allows the detector to be integrated with a smart home system
- Self-diagnosis : constantly checks the operation of the sensor and the internal circuits of the device
- Fault indication : informs about incorrect operation of the sensor
- TEST button : allows you to easily check the operation of the sound and light alarm
- Independent power supply : the sensor also works during a power outage in the electrical system
- Flexible installation : the sensor can be screwed, glued with double-sided tape or placed on a flat surface
- Compliance with EN 50291-1:2018 + AC:2021 : confirms compliance with the requirements for domestic carbon monoxide detectors
Multi-level carbon monoxide warning system and certification
The carbon monoxide detector uses several methods to notify you of a detected threat. A loud audible signal alerts people in the home, The red LED provides an additional visual message. This combination reduces the risk of missing the alarm and facilitates a quick response. The WiFi module expands the warning system with instant push notifications in the Tuya Smart or Smart Life app . The carbon monoxide detector meets the requirements of the EN 50291-1:2018 + AC:2021 standard for electrical carbon monoxide detectors in residential premises. Certification confirms that the detector has been verified against specific technical and safety requirements . Installing a CO detector also prepares the building for fire safety regulations. The detector should not be considered a substitute for proper ventilation, periodic system inspections, and maintenance of heating equipment.
