E2S GNExS1 Explosion Proof Sounders

 

E2S GNExS1 Explosion Proof Sounders for Hazardous Area Signalling Applications

The GNExS1 alarm Explosion Proof Sounders are suitable for Zone 1 & Zone 2 applications – certified to ATEX and IECEx. Sound level ouputs are up to 117dB(A) at 1 metre with a choice of 64 alarm tones and 4 remotely selectable stages. The alarm tone frequencies for the first 2 stages are independently selectable. The GNEx range features enclosures manufactured from GRP (glass reinforced polyester), moulded in natural red, but also available in other colours. The re-entrant flare horn is high impact, fire retardant ABS. All models have two M20 cable entries, large termination areas containing in & out terminals and an ingress protection of IP66/67. The AC voltage model has a range of 100-260vac & dc – suitable for 110Vdc gas detection systems.
