Photocell for night only operation

  • plug-in modular construction of the censor (Nema base)
  • automatic control of the red lighting according to ambient light with adjustable triggering level (set up by default in compliance with ICAO)
  • timer to prevent the functioning of the cell at inopportune times (lightning)

The ambient light sensor should be mounted upright, away from artificial light (eg., floodlights), and in a location that will enable its sensor window to have an unobstructed view of the polar sky (eg., pointed north in the northern hemisphere).
