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
