Description

The white color XLFE-MIA, with an intensity greater than 20,000 candles in daytime operation and greater than 2,000 candles in nighttime operation, complies with ICAO annex 14 for aviation obstruction warning lights of medium-intensity type A (corresponding to the FAA type of initials L-865).

The XLFE-MIA series has been designed for Zone 1 with an ‘Ex db’ optical source. The particular design avoids any type of optical error typical of the glass globes. The lamp body performs both the function of explosion protection and heat sink, thus avoiding the use of resin-coated optics, which are subject to deterioration over time. As required by the ICAO regulations, the XLFE-MIA series has a flashing operation, standard at 20 fpm, upon request at 40 fpm. The light source also complies with EN/IEC 60079-28 standard (“op is” protection). The installation is eased by the reduced dimensions, the wiring is done with cable gland in a ‘Ex eb’ enclosure, avoiding the use of sealed cable glands or the resin finishing at high heights. The signalling device is not a stand-alone device but it is part of a system that provides power from a control panel. This choice reduces maintenance operations by making the power supplies accessible from the control panel. With this system it is possible to manage the control of the lighting equipment failures, the eventual switching on of the spare indicators, the synchronization between different control panels also via cable or GPS technology.
