www.dialight.com vigilant? series led based l-856 high intensity (white) strobe application: the dialight vigilant? series high intensity led white strobe is the first all led l-856 unit designed for the lighting of communication towers, smoke stacks, broadcast towers and other tall obstructions to aerial navigation, as specified by the faa. a high intensity system consists of 3 flash heads, 3 power supplies per level and 1 controller for the entire system. the flash heads will be placed on up to six levels of the structure for a maximum of 18 synchronized flash heads for a single tower. the 3 flash heads will provide 360 degrees of coverage. unlike conventional xenon flashtube technology, little or no maintenance is required during its lifetime, drastically reducing maintenance costs associated with tower climbs. working voltages of less than 200vdc are significantly less than those of xenon flashtube designs; therefore, this system represents an advance in safety. use of led technology also provides a more shock and vibration resistant design, ensuring consistent flash intensity every time. this ip66 rated product is factory sealed to ensure water tight seals are not compromised over the life of the strobe. additionally, like all of dialights obstruction lights, patented optics provide sharp cutoff drastically minimizing light pollution and ground scatter. us patent #7,281,821 other patents pending mdtf856x001_a flashhead weight: 85 lbs operating voltage: universal 120 - 277 240vac 50/60hz effective intensity: white day 270,000 cd white twilight 20,000 cd white night 2,000 cd wattage: white day 250w white twilight 30w white night 10w power factor: >0.9 ambient temp: -40of to +131of (-40oc to +55oc) synchronization: multiple unit sync from single controller (operates with other manufacturers of gps sync devices) order code: part number description d156-a33-270 (1) - l -856 flash head and supply D156-A33-CTR (1) - controller d156-a33-sys (3) - l-856 flash heads and supplies, (1) - controller, (1) junction box d156-a33-lvl (3) - l-856 flash heads and supplies,(1) junction box d1rw-c13-008 (1) - l-864/l-865 antenna obstruction light and aol interface boards dialight reserves the right to make changes at any time in order to supply the best product possible. the most current version of this document will always be available at: http://www.dialight.com/assets\brochures_and_catalogs\signaling\mdtf856x001.pdf certifications & ratings: w faa ac no: 150/5345-43f w faa engineering brief no. 67 qualified by : w intertek etl compliant to: w dgac mexico features & benefits: w complete performance 5 year warranty w shock and vibration resistant w patented optic with sharp beam cutoff w minimum ground scatter (community friendly light pattern) w high impact polycarbonate lens w specialized lens coating providing superior uv, scratch, and chemical resistance w factory sealed for an ip66 water ingress protection w rugged all metal mounting base w extremely low rf interference 12.70 (322.61) ref 30.84 (783.3) ref 21.12 (536.3) ref
