MIR-SM200
The MIR-SM200 is a wireless smoke detector for reliable fire safety monitoring.
Real-time smoke detection, alarms, and remote alerts via gateway and APP.
Smoke Detection for Early Fire Warning
Detect smoke conditions in the environment around the clock. When the smoke concentration reaches the alarm threshold, the device immediately sounds and triggers visual alarms, and reports via the gateway for remote alert through the APP.
Local High-Decibel Sound and Light Alarm
When the smoke sensor detects smoke, the device immediately sends out a high-decibel sound and light alarm signal of >85 dB. The loud alarm can be heard throughout the house, reminding you to take timely action and help protect your family and property.
Troubleshooting Security guarantee is effective at all times
The product has a fault self-check function, which can effectively avoid safety hazards caused by faults.

Technical Specifications
The MIR-SM200 Wireless Smoke Detector combines photoelectric smoke detection with wireless connectivity for continuous indoor fire safety monitoring. When smoke reaches the alarm threshold, the detector immediately activates a local sound and visual alarm while reporting the alarm through the gateway for remote notification via the APP.
Supporting Matter / Wi-Fi wireless communication, a compact battery-powered design, fault self-check and low-battery warning, the MIR-SM200 provides a practical smoke monitoring solution for connected homes and other indoor environments requiring both local warning and remote alarm awareness.

A smoke detector may operate for long periods without an alarm event, which makes stability and routine status verification particularly important.
The MIR-SM200 has undergone testing across 17 test categories and more than 700 test cases. Together with its fault self-check and low-battery warning functions, these tests are intended to support stable performance throughout normal operation.
The detector brings together four important functions in one compact device:
Detection + Local Alarm + Wireless Reporting + Device Self-Check
This makes the MIR-SM200 more than a basic stand-alone alarm and better suited to connected fire safety monitoring applications.
