World-leading warning signalling manufacturer E2S introduces a new range of explosion proof horns and loudspeakers.

The new GNEx family, comprising of GNExS1 (117db @ 1m) and GNExS2 (123db @ 1m) is manufactured from lightweight and cost effective GRP, and offers excellent corrosion resistance for use in harsh environments both offshore and onshore. 

Both models offer a choice of 45 different alarm tones, including those that meet the PFEER regulations, while a second or third tone can be selected using additional control wires, providing 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 GNEx explosion proof sounders and loudspeakers come with ATEX and IECEx approvals; other approvals such as UL, GOST R and InMetro will follow soon. The GNExS1 sounder has a certified temperature range of -60°C to +50°C at Ex d IIC T4, with extended temperature range of +70°C at IIB T4, allowing its installation in almost all Zone 1 (Cat 2G) and Zone 2 (Cat 3G) areas. 

The flame paths in the new design use a large screw thread instead of the usual spigot joint, making it much easier to disassemble, saving time and money during installation. All GNEx products are supplied in a standard red colour; however other colours are available optionally.

Mechtric has more than 40 years’ experience in the supply and support of a comprehensive range of sounders, beacons, loudspeakers, voice alarms and wide area signalling equipment for the mining, oil and gas, hazardous area, industrial and marine markets.
