E2S, one of the world’s leading warning signalling manufacturers, has announced its new GNExS1 (117db @ 1m) and GNExS2 (123db @ 1m) explosion proof horns and loudspeakers. Manufactured from lightweight and cost effective glass-reinforced polyester (GRP), the GNEx family offers outstanding corrosion resistance for use in the harshest environments both offshore and onshore. Both models offer a choice of 45 different alarm tones, including those that meet the PFEER regulations, and a second or third tone can be selected using additional control wires giving the versatility of multiple tones from a single unit at a lower cost. The 15 watt GNExL1 and 25 watt GNExL2 loudspeakers are available in 8 Ohm, 16 Ohm and 100V Line versions. In/Out terminals eliminate the need for additional junction boxes in multiple device installations.
The units are launched with ATEX and IECEx approvals; other approvals such as UL, GOST R and InMetro will follow soon. The GNEx S1 sounder has a certified temperature range of -60C to +50C at Ex d IIC T4, with extended temperature range of +70C at IIB T4 so it can be installed in almost all Zone 1 (Cat 2G) and Zone 2 (Cat 3G) areas.
A key feature and benefit of the new design is that the flame paths use a large screw thread instead of the usual spigot joint, making it much easier to disassemble, saving time and money during installation. The standard colour for all GNEx products is red, other colours are available as an option as are alternative options on thread entries in place of the standard 2 x M20.
