Said to be suitable for Zone 1, 2, 21 and 22 hazardous location signalling applications the GNEx beacons have extended temperature range with IECEx and ATEX Ex d approvals. For high ambient light or long distance signalling the GNExB2 beacon is available in 10, 15 and 21 Joule variants producing up to 902cd – a very high output Xenon strobe, according to the makers. The smaller sized GNExB1 is available for where a 5 Joule (up to 117cd) unit meets requirements. Three flash patterns and second stage, set by users, are a standard feature with all GNEx beacons, depending on base model and power (DC or AC) supply.
On-site an installer can remove and replace the lens filter, such as for colour changes. Polycarbonate, UV stable lenses are available in Amber, Blue, Clear, Green, Magenta, Red and Yellow as separate spare parts. Installation time is minimised by design with the GRP enclosure having a threaded flame path, multiple cable entries and a large termination area.
Complementing the GNEx range is the GNExJ2 Ex d junction box, which, having multiple cable entries and terminal configurations is said to be suitable for a variety of applications. Both 15 and 21 Joule versions can be supplied as a plate mounted assembly configured with up to four Xenon strobe beacons with a junction box or five beacons without a junction box. The GNEx range includes alarm horn sounders, PA loudspeakers and manual call points for activation of fire alarms, gas detection and emergency shutdown systems. Visit www.e2s.com.
