HotlineGNExS1-R Radial Alarm Sounder / Horn
The flameproof GNExS1-R alarm sounder with a radial horn. Suitable for Zone 1 & Zone 2 applications - certified to ATEX and IECEx.
The radial horn on the compact GNExS1-R distributes the warning signal omni-directionally. Sound level ouputs are up to 115dB(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 omni-directional 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.
