With a loud alarm of ≥85 dB, audible from a distance of 3 meters, and full 360° coverage, the device effectively increases the safety of household members. The compact ceiling design of 125 × 125 × 33 mm and dual AA battery power supply ensure convenient installation and a long service life of up to 3 years. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"Smart smoke detector on a light ceiling, white smoke rising below\" src=\"https:\/\/assets.innpro.pl\/21014\/27882\/1.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Accurate smoke detection and fewer false alarms\u003c\/h3\u003e\u003cp\u003e The use of dual optical detection technology allows the detection of both white and black smoke, which significantly increases the efficiency of the sensor. Multi-standard optics ensure sensitivity and accuracy of measurements, while reducing the risk of unnecessary alarms. In addition, the device performs automatic self-tests, which can also be triggered via the app, ensuring that the system is working properly at all times. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"Smart smoke detector on the ceiling, bright smoke rising below\" src=\"https:\/\/assets.innpro.pl\/21014\/27882\/2.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Integrated alarm system for the whole home\u003c\/h3\u003e\u003cp\u003e The sensor works with a dedicated Meross hub (not included), allowing you to create a connected alarm system. If one device detects smoke, all paired sensors trigger an alarm, increasing the effectiveness of alerts throughout the home. Even if the hub has no internet or power, local communication continues to work, ensuring uninterrupted protection. The hub itself has an audible alarm with a volume of 110 dB and an extremely fast response time of 2 ms. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"Floor plan of a two-story house with smoke detectors installed in the rooms\" src=\"https:\/\/assets.innpro.pl\/21014\/27882\/3.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e Smart scenarios and full control via the app\u003c\/h3\u003e\u003cp\u003e With the Meross app, you can create automations that improve safety and comfort. For example, smoke detection can automatically turn off other devices in your home. The app also lets you view event history up to 10 years ago and sends notifications about alarms, low battery, device issues, or when your device is offline. Important alerts can bypass your smartphone's silent mode, ensuring you don't miss important information. \u003c\/p\u003e\u003cp\u003e\u003cimg alt=\"Burning pan on electric stove in kitchen\" src=\"https:\/\/assets.innpro.pl\/21014\/27882\/5.jpg\"\u003e\u003c\/p\u003e\u003ch3\u003e User comfort and functions adapted to everyday life\u003c\/h3\u003e\u003cp\u003e Do Not Disturb mode allows you to turn off the indicator light and low battery notifications at night, promoting a peaceful sleep.
