The explosion-proof industrial IP telephone TESLA 4FP 153 92/S is designed for reliable digital voice communications in hazardous industrial areas. It is used at oil and gas, chemical, power, and mining facilities where integration into modern IP networks and reliable communications in explosive environments are required.

This model supports VoIP technology and SIP protocols, allowing integration into corporate telephone networks, IP PBXs, and dispatch systems. This makes the telephone an optimal solution for modernizing existing infrastructure and transitioning from analog communications to digital control and monitoring systems.

The device's housing is made of shock-resistant, antistatic material that is resistant to mechanical stress, moisture, and aggressive environments. Its IP66 rating guarantees complete dustproofness and protection against powerful water jets, ensuring reliable operation both indoors and outdoors in industrial settings. The phone features a stainless steel push-button dialer designed for intensive use, including operation with gloves. Programmable function keys allow quick calls to the dispatcher, emergency services, or preset contacts. Call hold, redial, and auto-answer functions are supported.

For operation in high-noise environments, the device is equipped with a powerful ringer (up to 90 dB) and optical call signaling. Adjustable speaker and microphone volume ensure high-quality communications even in harsh industrial environments.

Power is supplied via PoE (Power over Ethernet), simplifying installation and reducing the cost of installing additional power lines. Operation from an external power source is also possible.
