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.
