Xenon Strobe Beacon

Upgraded Product

  • Lower in-rush electronics
  • Enhanced light output
  • A4 316 stainless steel guard as standard

Description

The GNExB2X21 beacon produces over 900cd effective – a very high output Xenon strobe flash as required for efficient signalling in environments with elevated levels of ambient light. The optically enhanced field replaceable colour filter optimises the strobe output and is constructed from UV stable PC. The GRP enclosure features a threaded flame path, triple cable entries and a large termination area – all of which significantly reduce installation time. SIL1 & SIL2 Route 2H compliant to IEC61508 (2010) as standard.
