Features
● Light distribution and chromaticity of the airport sequency flashing light conforming to the specifications contained in FAA-E-2628 and CAAC of China
● Low-Voltage flashtubes ensures low operation voltage of the whole system
● Self-alignment optical component without need of recalibration when replacing bulb as well as optical components
● Elevated type and in-pavement type
● The main body is made of aluminum alloy with anti- corrosion surface, all fasteners are made of stainless steel, suitable for harsh environment application
● The prism of in-pavement type is made of tempered glass material, which can withstand wind and sand erosion
● Upper cover of in-pavement type featured by equal- strength design and forging craft, which has premiummechanical and carrying capacity, and shock resistance
● Elevated type achieves IP65-grade protected from total
dust ingress, and in-pavement type, IP68-grade, that can withstand inner pressure of up to 138kpa or water pressure generated from aircrafts’ impact on the optical window
● High-precision machining to ensure all dimensional quality and precision
● Each lighting fixture comes with unit control cabinet that has concise cable layout, which is easier for maintenance and servicing
● Both main control cabinet and unit control cabinet have self-contained CPUs, which runs independently and operate in synergy via BUS communication
● Any component failures will not result in breakdown of system, ensuring reliable system operation
● The system has detection functions for bulb lifetime, flash skips(misfiring), on-line faults, etc.
● Main control cabinet equipped with LCD display, which accumulates statistical records of system operation
● Monitoring system achieves remote control and uploads of operation status
● Circuits, power and communication cables are equipped with lightning protection, conforming to the requirements contained in FAA
● The elevated fixture can be connected to both one or two-inch frangible tube, which ensures convenient and secure installation
●Forged frangible couplings with precision machining, whichcomplies with FAA requirements and ensure reliable and stable performance
