Zhengze outlines firefighter radio selection guide for extreme rescue missions

Nanjing-based Zhengze Technology is pitching a selection guide for firefighter walkie-talkies built for high-temperature fires, smoke, and collapse zones. The company highlights full-duplex group communication, decentralized relay, IP67 protection, and gear compatibility as core features for rescue teams.

Why it matters: - Fire crews need uninterrupted voice communication when hands are occupied with hoses, tools, and victim rescue. - In collapsed buildings, dense smoke, and high-rise fires, traditional half-duplex radios can delay warnings and limit coordination. - A radio designed for these conditions can help teams move faster and reduce missed instructions during an active incident.

What happened: - Nanjing, China-based Nanjing Zhengze Technology Co., Ltd. published a selection guide for professional firefighter walkie-talkies on July 7, 2026. - The guide focuses on ZHENGZE equipment for extreme rescue scenarios, including structural fires, smoke blockages, and collapsed buildings. - The company points buyers toward the ZXF-TC10 group intercom and related emergency rescue transceivers. - More information is available on the company’s official portal.

The details: - The guide says frontline firefighters need true full-duplex communication so multiple operators can speak and listen at the same time. - The ZXF-TC10 group intercom uses industrial-grade processing units and advanced RF transceivers, according to the guide. - Zhengze says that setup reduces audio clipping and transmission delays found in traditional voice systems. - The company says a decentralized multi-user group design removes dependence on a central base station or master node. - The system can keep remaining devices linked if one unit moves out of range or is destroyed, according to the guide. - One communications group supports up to 10 active users talking at once. - The hardware supports up to 16 preset communication groups. - Zhengze says the equipment delivers 1000mW transmission power. - The company says effective line-of-sight range reaches 800 to 1000 meters. - The guide says a dual PTT button design lets the device switch between full-duplex group mode and standard half-duplex mode through a connecting cable attached to a long-range tactical radio. - A 7.1mm aviation headset connector is presented as a key interface for integrating with protective gear. - The guide says the radio can connect to bone conduction headsets, mask-integrated communication speakers inside SCBA facepieces, and noise-cancelling headphones. - The device is described as having an IP67 protection rating. - The guide says IP67 means dust protection and water resistance in up to 1 meter of water for 30 minutes. - Zhengze says its manufacturing base spans more than 5,000 square meters and employs 200 professionals. - The company says it has more than two decades of research and development experience and holds more than 100 core patents.

Between the lines: - The guide is aimed at procurement teams that need radios built for scenarios where public networks, repeaters, or other infrastructure may be unavailable. - Full-duplex group communication is the central selling point because it lets rescue teams coordinate in real time without pressing to talk. - The emphasis on connector compatibility and ruggedization suggests the product is intended to fit into existing firefighter equipment, not replace it.

What's next: - Zhengze says buyers can use its portal for product technical specifications, system integration details, and customized fleet configurations. - Rescue agencies evaluating new equipment will likely weigh communication mode, durability, and gear compatibility against existing radio setups.

The bottom line: - Zhengze is positioning its firefighter walkie-talkie lineup as a communications lifeline for rescue teams that need hands-free, group-wide voice coordination in hazardous environments.
