Why emergency telephones are required in hazardous and industrial environments

Eaton’s FHF range delivers reliable emergency voice communication for hazardous and industrial environments, where safety, compliance, and uninterrupted communication are critical.

Designed for safety‑critical applications, these hazardous area and industrial telephones are engineered to withstand extreme temperatures, shock, vibration, dust, and humidity - ensuring dependable performance when it matters most.

Ideal for marine, chemical, petrochemical, pharmaceutical, and oil & gas industries, FHF telephones are manufactured to the highest global standards and certified for use in hazardous locations.

Simple integration with existing industrial and safety systems

Upgrade to the latest IP technology with ease, while keeping costs to a minimum. FHF phones can be easily retrofitted to replace legacy systems or seamlessly integrated with existing paging, public address and alarm  - helping extend the value of your current infrastructure.
