Installation Guidelines
- Installation must be performed by a qualified electrician with power disconnected
- Maximum 4m height for indoor use only, away from temperature-sensitive areas
- Ensure no large objects obstruct the detection area (sensor cannot detect through objects)
- Avoid placement near strong-reflecting objects, wifi routers, or microwave ovens
- Detection range optimized for 25℃ environment - performance varies with temperature
- Detection optimized for tangential movement - radial movement detection is shorter
