Monitoring
On request, a light emission source status monitoring module integrated in the device is supplied. In the event
of a fault or failure it promptly returns the open circuit information to the secondary circuit of the isolation transformer.
2.5
Arctic kit
The arctic kit option meets the FAA specifications (Engineering Brief N.67) preventing the formation of ice on
the protective transparent glass by heating the body of the fixture near the glass.
The heater automatically activates when the temperature falls below -1 °C and is turned off when the detected
temperature is higher than +10 °C.
