The built-in LCD display on the device itself gives you a quick local overview of the smoke concentration status and battery charge at any time.\u003cbr\u003e ---\u003cbr\u003e Key benefits of the KD122LH smart smoke detector\u003cbr\u003e\u003cbr\u003e Instant smart notifications (WiFi connection): When the device detects smoke, it not only triggers a local siren, but also sends an alert to your mobile phone via your home 2.4 GHz WiFi network. This way, you can take action even when you are not at home.\u003cbr\u003e Clear LCD Display: The built-in real-time display shows the current smoke concentration in the air and the exact battery status, eliminating the guesswork of device operation.\u003cbr\u003e Dual warning (Sound and light): In case of danger, the device triggers an extremely loud audible alarm with a volume of up to 85 dB (at a distance of 3 meters) and an intensely flashing red LED light, ensuring that you will not miss the alarm even during deep sleep.\u003cbr\u003e Advanced photoelectric technology: The built-in optical (photoelectric) sensor is extremely sensitive to slow-smoldering fires that produce a lot of thick smoke, while being designed to minimize the possibility of false alarms (e.g. due to water vapor).\u003cbr\u003e Long lifespan and low power consumption: The sensor itself boasts a lifespan of up to 10 years, and the included AA batteries provide up to 3 years of operation due to their extremely low standby power consumption.\u003cbr\u003e\u003cbr\u003e ---\u003cbr\u003e Technical specifications and features of the detector\u003cbr\u003e The KD122LH Smart Wireless Smoke Detector is designed with easy installation, long-lasting reliability, and seamless connectivity in mind. Below are all the technical data that confirm the superior quality of the device:\u003cbr\u003e\u003cbr\u003e Sensor type: Optical (photoelectric) smoke sensor\u003cbr\u003e Gas detected: Smoke (early stages of smoldering and fire)\u003cbr\u003e Alarm type: Loud audible alarm, light (LED) and remote notification in the app\u003cbr\u003e Alarm volume: ≤85 dB at a distance of 3 m\u003cbr\u003e Connectivity: WiFi standard 2.412 – 2.480 GHz (transmission power max +16 dBm @ 802.11 b)\u003cbr\u003e App Compatibility: Works with Tuya Smart and Smart Life apps\u003cbr\u003e In-app features: Receive remote alarms, low battery alerts, event history\u003cbr\u003e Local control: TEST button for quick operation check and muting\u003cbr\u003e Power supply: 3 x AA batteries (batteries included)\u003cbr\u003e Current consumption: In standby mode ≤2 µA, during active alarm \u0026lt;120 mA\u003cbr\u003e Battery life: Up to 3 years of operation\u003cbr\u003e Sensor life: Up to 10 years of stable operation\u003cbr\u003e Mounting method: Easy mounting on wall or ceiling (screw and wall insert included)\u003cbr\u003e Operating conditions: Temperature from -10°C to +50°C, relative humidity \u0026lt;95% (non-condensing)\u003cbr\u003e Dimensions: 85 x 47 mm\u003cbr\u003e Weight: 85.5g\u003cbr\u003e\u003cbr\u003e ---\u003cbr\u003e Why choose an optical (photoelectric) smoke sensor?\u003cbr\u003e Unlike older ionization detectors, optical or photoelectric smoke detectors operate on the principle of a light beam inside a measuring chamber. When smoke particles enter the chamber, the light is scattered and focused on a photosensitive sensor, which immediately triggers an alarm. This technology has been proven to be most effective in detecting smoldering fires – for example, overheated electrical wiring, smoldering upholstered furniture or mattresses – which are the most common causes of household fires at night. By purchasing the KD122LH model, you ensure the highest level of safety against such hazards.\u003cbr\u003e ---\u003cbr\u003e Easy to install and use in any space\u003cbr\u003e Thanks to its compact dimensions (85 x 47 mm) and neutral white color, the smoke detector blends inconspicuously with any interior. It is ideal for installation in key areas such as:\u003cbr\u003e\u003cbr\u003e Bedrooms and children's rooms: For maximum safety during sleep, when our senses are most vulnerable.\u003cbr\u003e Living rooms and hallways: Where the most electrical consumers and passageways are located.\u003cbr\u003e Kitchens and dining rooms: Where the risk of fire from cooking is greatest (place appropriately away from direct steam).\u003cbr\u003e Garages and offices: To protect your work environment and stored vehicles.\u003cbr\u003e\u003cbr\u003e Installation is extremely simple. The included kit includes a screw and wall insert, allowing for quick mounting to a wall or ceiling. After installing the batteries, you can easily connect the device to your home WiFi network via the Tuya app on your smartphone.\u003cbr\u003e ---\u003cbr\u003e Frequently Asked Questions (FAQ)\u003cbr\u003e 1. How does smartphone notification work and do I need a special control panel?\u003cbr\u003e No, you don't need any additional hardware or control panels to use the smart features. The KD122LH smoke detector connects directly to your existing home WiFi router (2.4 GHz frequency). Through the free Tuya Smart or Smart Life app, you will receive push notifications about alarms, low battery levels and view event history anywhere in the world where you have internet access.\u003cbr\u003e 2. How often do I need to test the device and replace the batteries?\u003cbr\u003e It is recommended to regularly check the device's operation once a month by pressing the built-in TEST button. This will trigger a short sound and light signal and confirm that the device is working properly. The included 3 x AA batteries have a lifespan of up to 3 years. When the batteries are low, the device will alert you with a local signal and a notification in the app.\u003cbr\u003e 3. What to do when an alarm is triggered?\u003cbr\u003e When the alarm sounds, stay calm and immediately investigate the source of the threat. If it is a non-dangerous source (e.g. a small amount of smoke from burning food), you can silence the alarm and ventilate the room. In the event of an actual fire, however, immediately leave the building, help other household members and immediately call the emergency services (112). The rapid response that this detector allows you to provide saves lives.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e Responsible persons:\u003cbr\u003e Kruger\u0026amp;Matz - Lechpol Electronics Leszek Sp.k.

Make sure your phone is connected to a 2.4 GHz WiFi network.\u003cbr\u003e • Pairing: In the app, select \"Add Device\" -\u0026gt; \"Security \u0026amp; Sensor\" -\u0026gt; \"Smoke Detector (WiFi)\".\u003cbr\u003e • Activation: Hold down the \"Test\" button on the detector until the light starts flashing quickly (entering pairing mode).\u003cbr\u003e • Confirmation: Follow the instructions in the app until the connection is successful.\u003cbr\u003e\u003cbr\u003e Useful tips:\u003cbr\u003e • Monthly Testing: Press the \"Test\" button regularly to check the siren and WiFi connection. The app will send you a notification that the test was successful.\u003cbr\u003e • Positioning is key: Place the detector in the center of the ceiling in bedrooms, hallways, and living rooms. Avoid the kitchen directly above the stove to prevent false alarms from cooking.\u003cbr\u003e • Sensor cleanliness: Remove dust from the detector once a year with a vacuum cleaner or a dry cloth. Dust inside the chamber can cause false alarms or reduce responsiveness.\u003cbr\u003e • Battery and WiFi: Smart devices consume more power than regular devices. When you receive a \"Low Battery\" notification on your phone, replace the battery immediately. We recommend using high-quality alkaline or lithium batteries.\u003cbr\u003e\u003cbr\u003e Warnings:\u003cbr\u003e • Do not paint the detector: Paint can clog the air vents and prevent smoke from reaching the sensor.\u003cbr\u003e • WiFi range: Make sure the location where the detector is installed has a stable WiFi signal. If the signal is weak, the detector will still beep, but you will not receive a notification on your phone.\u003cbr\u003e • Lifespan: The sensors in smoke detectors have a lifespan of approximately 10 years. After this time, replace the device with a new one, regardless of whether it is still working.\u003cbr\u003e\u003cbr\u003e\u003ch2\u003eUser view\u003c\/h2\u003e\u003cp\u003e The Tuya KD122LH Smart WIFI Wireless Smoke Detector LCD is designed for those who want to increase safety in their child's room, home or even a vacation home - without complicated installations or worrying about whether the alert will arrive in time.
