R. STAHL's FX15 signalling solution withstands extreme environmental conditions, e.g. a wide operating temperature range of +70 °C down to ­55 °C. FX15 beacons feature an enclosure manufactured from corrosion-resistant glass-reinforced polyester (GRP) that is designed to provide IP66/IP67 protection. All fixings are stainless steel. While the standard finish is natural black, painted units with epoxy coatings in red, yellow and blue are also available.

The beacons are supplied with a robust stainless steel lens guard as standard to protect the flame-retardant polycarbonate lens. The light source is a xenon tube providing a high light output. FX15 beacons flash at a rate of one per second. Lenses are available in seven colours (red, amber, green, clear, blue, yellow, magenta). The Fresnel lens that covers the well glass and houses the xenon tube produces a flash energy of 5 Joules, which ensures an excellent luminous intensity of 49 cd for the clear version.

The beacons are suitable for use in a variety of onshore and offshore applications and environments, notably including marine use, the oil and gas sector, and skid packages. Operating voltages range from 24 and 48 VDC to 115 and 230 VAC. All units feature 3 x M20 cable entries that enable a variety of wiring and mounting options. FX15 flashing beacons are ATEX- and IECEx-certified, with other relevant approvals (GOST, PESO, Inmetro and North American listing) to follow soon. Essential installation material such as mounting brackets, straps, glands, tag and duty labels, along with replacement parts are also available at launch.
