Calibrated ambient sensor (photocell) for twilight-night intensity change in accordance with ICAO and FAA for all OBSTA lights or for the change of color and light-intensity

  • plug-in modular construction with plated contact surfaces
  • possibility to rotate the censor on its base
  • automatic control of the red or dual obstruction lighting according to ambient light in compliance with FAA and ICAO twilight/night triggering level (2 ouputs available for night and twilight)
  • 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).
