The FM-105 High Frequency Occupancy Sensor is a line voltage sensor that turns lighting on and off based on occupancy; and can hold lights off when sufficient daylight is available. It detects motion via high frequency electromagnetic waves and the Doppler principle. Because it can detect motion through many dense materials other than metal; the FM-105 can be installed behind fixture lenses and hidden from view.


  • Detects movement when installed behind low-density fixture materials; such as polycarbonate; acrylic and glass diffusers
  • Provides hold-off daylighting control when ambient light is greater than daylighting setpoint
  • Can be mounted hidden from view
  • Easy adjustment via trimpots
  • Mounting bracket facilitates installation in various mounting positions
  • Simple line voltage wiring does not require a power pack
  • Time delay adjustable from 10 seconds to 30 minutes
  • Adjustable sensitivity range up to 20 feet
  • The product meets the materials restrictions of RoHS
  • 120/277VAC; 50/60 Hz
