Two new explosion-proof horns and loudspeakers — the GNExS1 (117 dB at 1 m) and the GNExS2 (123 dB at 1 m) — are manufactured from lightweight and cost-effective glass-reinforced polyester (GRP). The GNEx family offers “outstanding” corrosion resistance for use in the harshest environments, both on- and offshore, says the company. Both models offer a choice of 45 different alarm tones, including those that meet the PFEER regulations. — European Safety Systems Ltd., London, U.K.
