Supply and fixing of illuminated LED Guidance SignBoard of not exc 1.00 sqm each board for runway code number 3 or 4 with an all-Aluminum weather-proof sturdy frame keeps the electronics protected from environmental hazards and mechanical enclosure will have designed such a way that it can be opened for maintenance from the front without any special tools. The top edge should have heavy-duty hinges that open the front door towards the top side and IP65 or above sealed to provide protection against dust and rain ingress and electrical connection of LED clusters should be designed in such a way that failure of a particular cluster or a group of clusters only marginally affects the illumination of the Signage. LEDs need to have more than 50,000 hours of operational life and do not heat up and electronics should be capable for operation from -20 °C to +55 °C and signboard shall be uniformly internally illuminated with required LEDs to achieve uniform illumination level and operated on AGL circuit without flickering including supporting frangible legs & frame etc. & sign shall comply as per ICAO Annex.14 Vol.I, ADM part 4 and ADM part 6 complete all as specified and directed by Engineer-in-charge. Note : -Old board are deposited in ATC.
