The HP79XEx IIC intrinsically safe radio is certifed to standards listed by IECEx. It has been developed to provide safe and reliable communication in hazardous environments by adopting the new materials, brand-new structural design and innovative IS circuit. With optimized RF solution and pioneering audio solution, it extends communication range and provides better audio. Moreover, the HP79XEx IIC prepares for the unexpected before it really happens, thanks to lone worker, man down, and precise positioning.

Wider range of operation temperature (in Ex area)

Thanks to new explosion-proof materials and advanced mechanical design, the HP79XEx IIC is built to work under temperatures from –25°C to 50°C in explosion-prone areas. With stаble and even heat dissipation, the HP79XEx IIC is engineered to work in the extreme conditions, bringing extra safety and efficiency to everyday work.

The HP79XEx IIC adopts innovative silicone encapsulation technology to prevent liquid, inflammable dust, or explosive gas from intruding internal circuits. With multiple circuit protection mechanisms, the HP79XEx IIC strictly limits the electrical circuit’s energy to a non-ignitаble level during operation. Meanwhile, the circuit contributes to 5W(VHF) TX power and 2-watt audio power, extending the communications distance and boosting the audio loudness.

Rugged Intrinsically safe Battery

The IS battery is secured to the radio by battery protection plate and an anti-falling battery latch. Even if the HP79XEx IIC is dropped by accident, the battery will never become detached to avoid potential sparks in hazardous circumstances. In addition, the HP79XEx IIC prohibits the user to use a non original “IS” battery which alerts the user when it identifies a non-original battery has been detected with prompts on screen and flashing red LED indicator, as the safety of life and property cannot be endangered by any risks.

Latest anti-static technology

Electrostatic discharges are a source of ignition in explosive risk areas. Taking this in mind, the HP79XEx IIC first adopts high-strength, explosion-proof materials to prevent static electricity on the surface. Then the HP79XEx IIC uses a dual-material technology to resist the build-up of static electricity. So the workers can freely use the HP79XEx IIC removing the threat to lives and properties from the potential risk of spontaneous combustion or explosion

Rugged and Certified

The HP79XEx IIC is certificated with IP6X and MIL-STD-810H after a whole list of reliability tests such as accelerated life testing, impact test for the radio with 2.4-inch screen, and drop test. It is rugged enough to withstand dust, shock, or sudden drop. The workers can use the radio Where-ever they encounter harsh environments.

Dual antimagnetic mechanism

In the area containing metallic compounds, the HP79XEx IIC resists magnetic metal dust and shavings from the environments to damage the speaker — maintaining outstanding audio clarity and longer service life. All lies in the dual antimagnetic mechanism.

Lone worker

Provides Lone Worker Protection and reassurance for those who work alone especially in dangerous environments, such as oil pipeline worker. If the HP79XEx IIC senses that the worker does not make any operation within a preset time, due to a worker becoming incapacitated and unable to move, this radio will automatically alarm and reports the location to the companion or control center for a welfare check.

Man down

Operative Down is ideal for emergency situation. If the worker has fallen and as a result has become unconscious or not able to move, the HP79XEx IIC automatically detects a sudden tilt towards the ground, and alarms and reports the location to the companion or control center for for a welfare check, this is vital to identifying dangers and preventing the loss of life

Precise positioning

With the built-in positioning module, the HP79XEx IIC supports the flexible combination of GNSS, BDS, GLONASS and Galileo satellite systems. Also, the HP79XEx IIC enhances positioning accuracy down to one meter, thanks to the dual-frequency positioning technology. Such reliable and accurate location information helps locate the individual that may need assistance during an emergency event

The HP79XEx IIC takes critical communications to a new level, with the efforts of Hytera Audio Lab, RF & Antenna Lab, Energy-efficient Lab, and UX Design Lab*. The HP79XEx IIC keeps the workers always connected,from superior audio quality to extended radio range. The HP79XEx IIC performs longer thanks to the longlasting battery. Moreover, the HP79XEx IIC facilitates the usage and management in terms of versatile connectivity and easy-to-use design.

Improved Speaker performance

Most explosion-prone environments are noisy, this radio provides clear and loud audio is the key to ensure effective communication among team members. The HP79XEx IIC, with a lighter and slimmer body, has a 2W speaker to deliver louder audio to improve team collaboration and work efficiency.

With cutting-edge audio processing technology adopted, the HP79XEx IIC delivers crisp, clear audio even in complex environments, ensuring clearer audio for Mission-critical and business-critical communications.

AI-based noise cancellation

The HP79XEx IIC adopts the most advanced AI-based noise cancellation algorithm and gets machine learning behavior. After learning and training thousands of noise samples, the HP79XEx IIC can quickly separate the human voice from the noise, allowing the workers to receive clear commands.

Water-porting design

The speaker has a unique water-porting design that can automatically expel water from the speaker’s acoustic cavity quickly. Even in heavy downpours, the HP79XEx IIC will still deliver clear audio.

Automatic gain control

Automatic gain control (AGC) automatically increases or decreases microphone gain to ensure consistently loud and clear audio output, regardless of how softly or loudly the workers are talking into the microphone.

Feedback suppression

Using the innovative feedback suppression algorithm, the HP79XEx IIC eliminates a feedback sound when two radios are too close, even 30 cm away from each other.

The standard 2150 mAh battery, together with the cutting-edge low power consumption technology, can outlast the shift. The workers can check the remaining battery and battery health on the radio and extend the battery life using the smart charger

Thanks to the new-designed powerful IS circuits and RF optimization solution, HP79XEx IIC features 5W(VHF) transmitting power and industry-leading receiving sensitivity (0.16μV), providing more smooth communications even at a distance or in the edge area, further enhancing personal safety and work efficiency.
