The ambient light sensor averages its measurement for 30 seconds. FAA: By default the lights turn ON when the ambient light decreases to not less than 35 footcandles (376.7 lux) and turn OFF when the ambient light decreases to not more than 60 footcandles (645.8 lux). ICAO: By default the lights turn ON when the ambient light decreases to not less than 100 lux and turn OFF when the ambient light increases to not more than 150 lux. In night mode, the LI will be illuminated as either a red, steady burning (ICAO Type A and B and FAA L-810) or flashing (ICAO Type E and FAA L-810F) fixture. In day mode, the fixture will not be illuminated. Light intensity & operation mode setting for FAA compliant light fixture The FAA compliant model comes pre-set to the correct intensity for L-810 steady or L-810(F) flashing burning red obstruction light in dusk-till-dawn mode. The intensity and operation mode is pre-set in the factory and does not need to be set by the user. Light intensity & operation mode setting for ICAO compliant light fixture The fixture will be supplied with the ICAO compliant optic. The obstruction light will be pre-set to the intensity setting specified by the customer for a red steady burning (ICAO Type A or ICAO Type B) or flashing (ICAO Type E) Low Intensity Obstruction Light in dusk-till-dawn mode. The intensity and operation mode is pre-set in the factory and does not need to be set by the user. Note: The ICAO Model and FAA Model have their own unique optic. The ICAO model cannot be used for FAA purposes and the FAA model cannot be used for ICAO purposes. The model required needs to be specified at the time of order. 6.1 GPS Syncronisation Avlite has utilised the latest advancements in GPS technology to develop an internal synchronisation system that is incorporated into the lights. Using overhead satellites, multiple LI fixtures (ICAO Type E and FAA L-810F only) are able to synchronise with other obstruction lights set to the same flash pattern. No additional power supplies, aerials or control systems are required, and with its microprocessor- based system, the GPS option is specifically designed to provide maximum reliability and performance over a wide range of environmental conditions. Operating Principle Each light operates independently and requires no operator intervention. A minimum of 4 satellites need to be in view for the built-in GPS receiver to collect time data. At dusk, the light sensor will turn the light on. If time data is available, the LI will come on synchronised to every other obstruction light with the same selected flash code. Synchronisation is achieved using an internal algorithm based on the highly accurate time base and time data received from the satellites. The satellite data is provided from a number of earth stations using atomic clocks as the time base. Continuous selfchecking ensures that the lights will continue to run in synchronisation. Light Activation At power-up the microprocessor checks that the internal GPS module is programmed correctly and is able to provide valid time base and time data. Once outside with a clear view of the sky, valid data should become available within 20 minutes. Note: Lights will not synchronise if different flash codes are selected. 10 Single Low Intensity Obstruction Light AV-OL-LI 7.0 Unpacking, Installation and Wiring WARNING: DO NOT connect directly to an unregulated power source. Connecting to an unregulated source may result in damage. WARNING: Do not stare into light emitting diode (LED) beams. WARNING: LED lights contain glass components. Do Not Drop.
