E2S launches new GRP sounders and manual call points at Offshore Europe

27 August 2013

E2S, one of the world’s leading warning signalling manufacturers, launched its new GNExS1 (117 dB@1m) and GNExS2 (123 dB@1m) explosion proof horns and loudspeakers at Offshore Europe, 3 - 6 September 2013. The GNEx family offers outstanding corrosion resistance for use in the harshest environments both offshore and onshore.

Manufactured from lightweight and cost effective glass-reinforced polyester (GRP), 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.

The GNExS1 sounders and speakers complement the GNEx range of ATEX and IECEx approved Exe d explosion proof manual call points in GRP housings. Designed for the manual activation of fire alarms, gas detection and emergency shutdown systems, the units are environmentally sealed to IP66. 

They meet the requirements for rugged, corrosion resistant non-metallic units for both onshore and offshore environments, and offer outstanding reliability when installed in harsh environments.

Available as standard in a range of colours, including striped versions, different systems can be colour-coded to enable rapid visual identification in an emergency.

Available with break glass, push button and push button with tool reset operation, a comprehensive range of standard accessories such as a stainless steel lift flap, labelling options for stainless tags and duty labels are available. Series and EOL resistors in a range of different values can be fitted to all models as required and DPDT switching and LED indicators can also be specified. 

The introduction of this new family complements the well-established alloy-bodied explosion proof and intrinsically safe call points, the BEx range of explosion proof sounders, beacons and loudspeakers, the E2x family of lightweight, corrosion free PPS plastic and impact-resistant ABS units and the intrinsically safe IS-mini modular sounder and beacon family.

E2S has more than 20 years experience in designing and manufacturing a comprehensive range of sounders, beacons, loudspeakers, voice alarms and disaster sirens for the oil & gas, hazardous area, industrial and marine markets.
