Overview

This document provides typical examples of combined optical and acoustic signaling devices compliant with ATEX standards, featuring terminal boxes (JBOX). These combinations are designed for hazardous environments requiring explosion protection.

Product Combinations

The document lists multiple typical configurations (TIPICO / TYPICAL 1 to 7) of signaling devices composed of ETH20MD beacons (4W or 10W), EVA50 sounders, and terminal boxes (JBOX). Variations include the number of sounders and beacons, and some configurations include mounting plates or stainless steel Exe terminal boxes.

Examples of Typical Combinations:

• TIPICO 1: ETH20MD 4W + EVA50 + JBOX
• TIPICO 3: ETH20MD 10W + EVA50 + JBOX
• TIPICO 4: ETH20MD 4W + 2 EVA50 + JBOX
• TIPICO 7: ETH20MD 10W + 3 EVA50 + JBOX

Certification and Compliance

All combinations comply with ATEX Directive 2014/34/EU and are certified for use in hazardous zones:

• Zones 1 and 2 for gas (Ex db IIB+H2 Gb, Ex db IIC Gb)
• Zones 21 and 22 for dust (Ex tb IIIC Db)

Temperature classes include T5 (max 100°C) and T6 (max 85°C), with operating temperature ranges from -20°C (optionally -40°C) up to +60°C or +40°C depending on the model.

Technical Features

• Protection rating: IP66, ensuring dust-tight and water-resistant enclosures.
• Terminal boxes (JBOX) facilitate wiring and installation.
• Devices include flashing beacons (ETH / 1 FLASH, ETH / 2 FLASH, ETH / 3 FLASH) combined with sounders.

Key Parameters and Limitations

• Power ratings for beacons: 4W or 10W.
• Number of sounders (EVA50) varies from 1 up to 3 per combination.
• Operating temperature range and certification class must be respected for safe use in hazardous areas.

Best Practices and Recommendations

• Choose combinations based on zone classification and required signaling intensity.
• Ensure proper installation using the provided terminal boxes to maintain ATEX compliance.
• Verify temperature class suitability for the specific hazardous environment.

Summary

This document serves as a reference for selecting ATEX-certified light and sound signaling device combinations suitable for various hazardous zones. It emphasizes compliance with safety standards, appropriate power ratings, and environmental protection to ensure reliable operation in explosive atmospheres.
