GNExS2 Alarm Horn Sounder 123dB(A)
The flameproof GNExS2 alarm sounder is suitable for Zone 1 & Zone 2 applications - certified to ATEX and IECEx.
Sound level ouputs are up to 123dB(A) at 1 metre with a choice of 45 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.
Features:
• Automatic synchronisation on multi-sounder system.
• Very large termination area.
• Ratchet adjustable stainless steel ‘U’ bracket.
• IN & OUT terminals.
• Independently selectable tones for 1st & 2nd stages.
