Tomar GNEXS1 Alarm Horn Sounder 117dB (A)-Intrinsically Safe
Tomar Electronics flameproof Tomar GNEXS1 Alarm Horn Sounder 117dB (A)-Intrinsically Safe, sounder stands as an exemplary solution tailored for Zone 1 and Zone 2 applications, holding certifications from ATEX and IECEx. Boasting a commanding sound level of up to 117dB (A) at a distance of 1 meter, this intrinsically safe alarm system offers not only power but also flexibility. With a selection of 64 alarm tones and four remotely selectable stages, users have the freedom to customize their alert system.
Independently selectable alarm tone frequencies for the initial two stages add a layer of adaptability. Constructed with enclosures made from durable glass-reinforced polyester (GRP), available in a natural red hue or alternative colors, the GNExS1 ensures resilience against environmental factors. The re-entrant flare horn, crafted from high-impact, fire-retardant ABS, further guarantees robustness.
Facilitating installation flexibility, the device incorporates two M20 cable entries. Its large termination areas house in and out terminals, simplifying the connection process. The GNExS1 achieves an ingress protection rating of IP66/67, safeguarding against dust and water, making it suitable for challenging conditions.
Designed to accommodate diverse power systems, the AC voltage model operates within a range of 100-260V AC and DC. Specifically, it proves compatible with 110V DC gas detection systems.
Features:
- Automatic Synchronization: Effortless integration into multi-sounder systems with automatic synchronization.
- Very Large Termination Area: Ample space provided for secure and convenient terminations, ensuring ease of installation.
- Ratchet Adjustable Stainless Steel ‘U’ Bracket: Equipped with a robust and adjustable stainless steel bracket for flexible and sturdy mounting.
- IN & OUT Terminals: Conveniently designed with both input and output terminals, facilitating straightforward connections.
- Independently Selectable Tones for 1st & 2nd Stages: Customizable alarm tones for the first and second stages, allowing tailored alert configurations.
- Four Remotely Switched Stages/Channels: Enhanced flexibility with four remotely switchable stages or channels for diversified signaling options.
