Upgraded Product

  • New UL & cUL approval for Class I Zone 1 and Class I Division 2 applications
  • Lower in-rush electronics
  • SIL2 compliant version with monitoring
  • A4 316 stainless steel guard as standard

Description

The STExB2X10 beacons produce a high output Xenon flash required for effective signalling in environments with elevated levels of ambient light. The field replaceable colour filter enhances the strobe and is constructed from UV stable PC.
The stainless steel enclosure features a threaded flame path, four cable entries and a large termination area – all of which significantly reduce installation time. SIL1 compliant to IEC61508 (2010) as standard. DNV type approved for exposed locations.
