About This

Please note: To get started, you will need 2 x 1.5V AA batteries (not included). This allows you to enjoy full-power protection right away.
【High-Sensitivity Photoelectric Detection】Utilizing an advanced infrared photoelectric sensor and an intelligent MCU chip, it accurately detects smoke during the smoldering stage or early phase of a fire. Once smoke density reaches the alarm threshold, it instantly triggers both audible and visual alerts. Ideal for homes, shops, factories, warehouses, and more, it provides critical time for safe evacuation.
【Unmissable Alarm Alert】With a loud alarm sound pressure of up to 85dB (tested from 3 meters), it offers strong penetration and remains clearly audible even during sleep or in noisy environments. Paired with a continuously flashing red LED indicator, it provides dual audio-visual warnings for comprehensive protection of life and property.
【Silence Function + Low Battery Alert】In alarm mode, press the test button to temporarily mute the device, avoiding false alarms triggered by cooking or guest smoking (use only after confirming the environment is safe). When battery voltage drops below 2.5V, the red light flashes every 55 seconds accompanied by a beep, reminding you to replace the batteries promptly and ensuring uninterrupted operation.
【Easy Installation】We thoughtfully include screws + expansion tubes and strong double-sided adhesive, supporting both drilled mounting and direct paste-on installation without damaging walls. Perfect for tenants, landlords, or temporary use, it installs quickly and easily without wiring. Powered by 2 AA batteries (not included), it covers approximately 20㎡ of space and is suitable for rooms with heights ≤6m.
【Durable Design + Self-Check Function】Constructed with SMT manufacturing technology and a rugged housing, it operates reliably in temperatures from -10°C to +50°C and environments with ≤95% humidity. Equipped with multi-status indicators for normal operation, alarm, and low battery, regularly pressing the test button allows for device self-check. The maze-style dust-proof design reduces false alarms when cleaned periodically, ensuring a long service life.
