In hazardous industries, communication devices are not just tools — they are part of your safety system.

Whether you are operating in oil & gas, chemical processing, or industrial manufacturing, every device carried into a hazardous area must meet strict certification standards. This is where the HAEXC FP103Ex and HAEXC SP104Ex stand out.

Both models are TÜV Rheinland GmbH certified, meeting internationally recognized ATEX and IECEx standards for use in Zone 1 and Zone 2 environments — areas where explosive gases or dust may be present during normal operations.

But beyond safety, these devices are designed for modern workflows, combining 4G connectivity, Push-to-Talk communication, and rugged reliability.

Built on German TÜV Rheinland Certification You Can Trust

The HAEXC FP103Ex and SP104Ex are certified by TÜV Rheinland GmbH, a globally respected German certification body known for strict testing and compliance standards.

This certification ensures that both devices are safe for use in Zone 1 (high-risk) and Zone 2 (moderate-risk) environments, where explosive atmospheres may be present during normal operations.

They are engineered to prevent ignition risks such as sparks or overheating, and are tested to operate reliably in extreme conditions from -20°C to +55°C.

For safety managers and operations teams, this means full compliance — without sacrificing communication performance.

HAEXC FP103Ex: Purpose-Built for Fast, Reliable Team Communication

The HAEXC FP103Ex is designed with one goal: make communication effortless in the field.

Its physical keypad is not just a legacy feature — it is a critical advantage in industrial environments. Workers wearing gloves or operating in harsh conditions can easily control communication without navigating touchscreens.

When paired with VoicePing, the device becomes even more powerful.

The dedicated PTT button allows instant talk with zero delay. The SOS button provides immediate emergency escalation when needed. And importantly, the keypad enables quick channel switching, allowing workers to move between teams or groups in seconds — something that is often slow or cumbersome on touchscreen devices.

This combination creates a workflow that feels closer to traditional radios, but with the flexibility of 4G communication.

Under the hood, the FP103Ex is built to last. Its IP68-rated rugged body, removable 4000mAh battery, and AI-enhanced noise reduction ensure that it performs reliably throughout long shifts in noisy environments.

For teams that depend on speed, simplicity, and reliability, the FP103Ex delivers exactly what is needed — nothing more, nothing less.

HAEXC SP104Ex: Smart Communication Meets Digital Workflows

The HAEXC SP104Ex extends these capabilities into a full smartphone experience.

Running on Android 14, it allows organizations to integrate communication directly into their operational workflows — from inspections and reporting to task management and data collection.

Like the FP103Ex, it includes dedicated PTT and SOS buttons, ensuring that critical communication functions remain instantly accessible at all times.

With VoicePing integration, users can still achieve fast Push-to-Talk communication. However, the experience shifts slightly — instead of relying on a keypad, the SP104Ex is optimized for app-based workflows, touch navigation, and richer interaction.

Its 50MP camera supports detailed inspections, while the larger display and increased memory make it suitable for running enterprise applications in the field.

This makes the SP104Ex ideal for teams that need both:

Reliable communication

• Access to operational data and tools
• VoicePing Integration: The Best of Radio and 4G

Both devices are certified compatible with VoicePing, enabling a seamless Push-to-Talk experience over 4G networks.

This combination delivers something unique.

On one hand, users get the instant communication experience of traditional radios — with physical buttons, quick channel switching (on FP103Ex), and immediate response.

On the other hand, they benefit from modern connectivity, including:

Unlimited range across locations

• No dependency on radio infrastructure
• Easy scalability across teams
• The result is a communication system that is both familiar and future-ready.

The choice between FP103Ex and SP104Ex depends on how your team communicates and works.

If your priority is fast, intuitive communication, especially in environments where gloves, noise, and speed matter, the FP103Ex offers a superior experience with its keypad-driven control and channel switching.

If your operations require digital workflows, inspections, and applications, the SP104Ex provides the flexibility of a smartphone while maintaining the same level of safety and reliability.

Both devices share the same foundation — TÜV-certified safety, Zone 1 and Zone 2 compliance, rugged construction, and seamless VoicePing integration.

Final Thoughts

The HAEXC FP103Ex and SP104Ex are more than intrinsically safe devices — they are communication systems designed for real-world industrial challenges.

With German TÜV Rheinland certification, dedicated PTT and SOS controls, and deep integration with VoicePing, they enable teams to communicate faster, respond quicker, and operate more safely.

In hazardous environments, those advantages make a real difference.
