Upgraded Product

  • New UL & cUL approval for Class I Zone 1 and Class I Division 2 applications
  • A4 316 stainless steel guard as standard

Description

The GNExB2LD2 utilises an array of high power Cree® LED’s, orientated to optimise visibility in any direction. The beacon can be configured as a steady beacon with a light output of up to 174 candela. Alternatively, for warning applications, five flashing modes, with a light output of up to 338 candela. DC voltage versions feature three remotely selectable stages enabling multiple warnings to be signalled. The field replaceable colour filter enhances the light output and is constructed from UV stable PC. SIL1 compliant to IEC61508 (2010) as standard.
