Ex Xenon Strobe GNExB2 X21 230vAC with CLEAR lens
The GNExB2X21 is an IECEx & ATEX approved explosion proof 21 Joule Xenon beacon. The robust IP66 corrosion proof GRP enclosure and extended temperature range ensures the GNExB2X21 is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.
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.
Features:
• Robust, corrosion proof GRP (glass reinforced polyester) enclosure
• Ingress protection IP66
• Automatic synchronisation on multi-beacon systems
• Choice of three flash rates: 1Hz, double and alternate flash
• DC voltage units feature remote change of flash rate function
• User replaceable Xenon tube mechanically secured against shock & vibration
• Glass lens & Stainless Steel guard
• Field replaceable colour filter (easaly change the lens colour)
• UV stable PC field replaceable lens colour filter
• Stainless steel fixings
• Triple cable entries
• Duplicate cable terminations (in & out for daisy-chain installations)
