Smoke Detectors & Fire Alarms

• 【Full-Stage Fire Detection 】Equipped with an infrared photoelectric sensor, this detector responds not only to visible flames but also captures smoke particles during the smoldering stage—often before smoke becomes widespread. Its built-in processor analyzes smoke density in real time and triggers instant audible and visual alerts once the threshold is reached. Offers precious extra seconds for evacuation, making it ideal for homes, shops, and more.
• 【Easy Setup】Installation is simple and tool-free: just detach the backplate, mount using screws or adhesive tape (both included), and insert batteries. With clear visual indicators—red LED flashes every 60 seconds in standby, blinks rapidly in silence mode, and flashes every 55 seconds with a beep for low battery—anyone can easily understand the device status, making it senior and beginner-friendly.
• 【Wide Environmental Adaptability】Built with weather-resistant materials and circuitry, it operates reliably in temperatures from -10°C to 50°C and up to 95% relative humidity. Suitable for cold winters and humid climates, it maintains consistent detection in common indoor environments while avoiding false triggers in high-dust or high-steam areas as noted in the manual.
• 【Quality Craftsmanship】Precision SMT manufacturing ensures solid soldering and stable circuit connections, minimizing failure risks. With ultra-low power consumption (standby current <15μA, alarm current <50mA), 2 AA batteries (not included) provide extended service. it’s lightweight yet durable—easy to install and built to last.
• 【Design for Safety & Convenience】Features a dedicated test button for regular function checks and a silence mode with safety reminders to prevent misuse. Everything needed is included—detector, backplate, screws, anchors, and adhesive tape—so you can install and use it right out of the box.
