GNExB2LD2 LED Multifunction Beacon
The GNExB2LD2 is an IECEx & ATEX approved explosion proof high output LED multifunction beacon. The robust IP66 corrosion proof GRP enclosure and extended temperature range ensures the GNExB2LD2 is suitable for all Zone 1, 2, 21 & 22 hazardous location signalling applications.
The GNExB2LD2 beacons utilise an array of high output LED's oriented to optimise visibility in any direction. The beacon can be configured as a steady status indicator or one of the effective flashing modes may be used for warning applications. The field replaceable colour filter enhances the light 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 five flash rates: 1Hz, 1.5Hz, 2Hz, double and triple flash.
• High and low power Steady modes
• Three remotely selectable stages/channels on DC versions.
• Glass lens & Stainless Steel guard
• UV stable PC field replaceable lens colour filter
• Stainless steel fixings
• Triple cable entries
• Duplicate cable terminations (in & out for daisy-chain installations)
