The flameproof BExBG21 Xenon beacons are suitable for Zone 1, 2, 21 and 22 applications. The BExBG21 21 Joule beacons are ideal for general signalling duties whilst their robust construction makes installation in the harshest of environments possible. The BExBG21 has three distinct user selectable flash patterns and for units with DC operating voltages a second stage flash pattern can be selected remotely. Additional features include a stainless steel guard and stainless steel mounting bracket as standard. The BEx range features enclosures manufactured from corrosion proof, marine grade copper free LM6 aluminium which is phosphated and powder coated. All models have two M20 cable entries, large termination areas containing in and out terminals and an ingress protection of IP66/67.
