【ZX-S21】
Wifi Smoke Detector

This S21 smoke sensor supports full-angle smoke capture with stable and responsive sensing performance. It precisely identifies tiny smoke particles generated by kitchen open flame, wire burning and other fire sources around the clock without dead detection zones. Even faint smoke can trigger the system quickly, avoiding missed fire risks caused by single-direction detection. It keeps continuous monitoring day and night to guard your space against sudden fire accidents reliably all year round.

Built-in WiFi wireless module compatible with Tuya Smart APP, the detector sends instant alarm messages to your smartphone no matter where you are. When smoke concentration hits the warning standard, your phone will receive pop-up alerts synchronously, so you can handle fire emergencies remotely in time. You can also run self-test and hush mute operations via the APP, realizing full intelligent remote control of your home fire safety system.

The round slim white body features a concise aesthetic that fits all indoor decoration styles perfectly. It comes with a slide-open battery compartment and matching mounting accessories, enabling quick ceiling or wall installation without complicated wiring. No professional technicians are required; users can finish setup independently within minutes. The compact structure won’t occupy extra space and blends seamlessly into kitchens, bedrooms and office environments.

Fitted with an imported high-power loud speaker, the detector emits loud sharp alarm sound when smoke exceeds the safety threshold. The high-volume local alert can be clearly heard in every corner of the room to remind indoor people to evacuate rapidly. The TEST/HUSH button allows you to manually test alarm function or temporarily silence false alarms easily, balancing powerful warning effect and convenient user operation.

Powered by replaceable 1.5V batteries with ultra-low power consumption design for long standby time, cutting frequent battery replacement costs. Its stable performance adapts to diverse environments, covering residential villas, hotels, shopping malls, factories, schools and hospitals. It serves as standardized fire safety equipment for both family daily protection and commercial public space fire prevention, meeting multi-scenario safety monitoring demands.
