GNExS1 Alarm Horn Sounder 117dB(A)

The flameproof GNExS1 alarm sounder is 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.
