E2S Warning Signals has added visual signals to its explosion proof and corrosion resistant GNEx family. Suitable for all Zone 1, 2, 21, and 22 hazardous location signaling applications the GNEx beacons have extended temperature range with IECEx and ATEX Ex d approvals. For high-ambient light or long distance signaling the GNExB2 beacon is available in 10, 15. and 21 Joule variants producing up to 902cd. 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.

The company says on-site removal and replacement of the lens filter, such as for color changes, is simple. Polycarbonate, UV stable lenses are available in amber, blue, clear, green, magenta, red, and yellow as separate spare parts.
Complementing the GNEx range is the GNExJ2 Ex d junction box, which, having multiple cable entries and terminal configurations is suitable for a large 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 new Xenon strobe beacon visual signals broadens the GNEx family which includes alarm horn sounders, PA loudspeakers, and manual call points for activation of fire alarms, gas detection, and emergency shutdown systems.
