Due to the special operating environment of petrochemical plants, there are safety risks such as combustible gas leaks and fires, which place stringent demands on the explosion-proof rating, reliability, and anti-interference performance of communication equipment. Traditional non-explosion-proof communication devices cannot meet safe production requirements, and they often suffer from delayed command delivery and incomplete coverage in scenarios such as emergency dispatching, safety broadcasting, and personnel calling. Based on petrochemical industry explosion-proof standards and the customer’s actual operational needs, Becke Telcom customized and deployed an industrial-grade integrated explosion-proof paging and calling solution to build a strong communication safeguard for safe production.

Customer Requirements
Explosion-Proof Communication and Amplified Paging:All terminal devices must comply with national explosion-proof certification standards, adapt to IIC-class hazardous environments, and provide reliable voice calling and public address broadcasting within explosion-hazard areas.
One-Touch Calling and Two-Way Intercom:Operators must be able to use explosion-proof telephones to make one-touch calls to the control center or designated posts, enabling hands-free two-way intercom for rapid hazard reporting and dispatch instruction delivery.
Zoned Broadcasting and Safety Announcements:During daily operations, the system should support zone-based broadcasting of safety instructions, operating procedures, and inspection reminders. In emergencies, it should be able to quickly initiate plant-wide or designated-area emergency broadcasts to deliver evacuation instructions and warning messages.
Multi-System Integration and Linkage:The system should integrate with the plant’s fire alarm system, combustible gas detection system, and SCADA system, enabling automatic broadcast announcements and location prompts when alarm signals are triggered.
Highly Reliable Operation and Maintenance:The equipment must withstand harsh outdoor and industrial conditions such as dust, moisture, and high temperatures, ensuring stable 24/7 operation. The control center should be able to centrally manage all terminals, including status monitoring and remote configuration.
Solution Deployment
Becke Telcom’s explosion-proof paging and calling solution deploys a professional converged communication dispatch system and core host platform in the plant control center, seamlessly integrating with the plant’s industrial-grade fiber-optic / bus network. The solution fully meets the communication, dispatching, and coordination needs of explosion-hazard work areas such as tank farms, loading and unloading zones, and pump rooms. It enables a dispatching model featuring centralized control by the control center and hierarchical management across different zones, matching the safety management characteristics of petrochemical plants operating in flammable and explosive environments.
Through the Becke Telcom professional dispatch console, operators in the dispatch center can directly initiate live voice dispatching to explosion-proof intercom telephones in designated work areas. The explosion-proof terminals can receive instructions in real time and respond quickly, ensuring that emergencies such as leaks and fires are handled promptly and that safety risks are minimized to the greatest extent possible.
The solution is fully compatible with and can be integrated with the plant’s existing PBX system, SCADA system, fire alarm system, and combustible gas detection system. It opens up communication links between these systems and the explosion-proof paging and calling system, enabling interconnection between the plant’s internal communication network and external public networks. At the same time, alarm-triggered targeted broadcasting can be activated automatically, significantly improving dispatch management efficiency and emergency response speed while meeting diverse needs for internal and external communication and multi-system collaboration.
All hardware devices in the solution use the standard SIP protocol and are uniformly registered to the Becke Telcom explosion-proof dispatch system over IP. This enables a full range of functions, including internal and external calling, multi-zone broadcasting, emergency dispatching, targeted paging, multi-party conferencing, and alarm linkage.
Core Products
The complete system includes a converged communication dispatch host, multimedia command and dispatch consoles, explosion-proof sound and light alarm telephones, industrial special telephones, paging amplifiers and industrial broadcast terminals, as well as explosion-proof alarm linkage modules and other full-featured petrochemical communication equipment. The system is designed to adapt to the complex operating conditions commonly found in petrochemical plants, including humidity, dust, high temperatures, and flammable or explosive atmospheres.
Conclusion
Ultimately, Baker Telecom built a stable, efficient, and secure explosion-proof paging communication capability for a petroleum company in Shenyang. This solution enables precise emergency dispatch and broadcast linkage for all or designated explosion-proof terminals within the plant, ensuring rapid and effective dispatch, coordination, and command deployment in the event of leaks, fires, or other flammable and explosive emergencies. This provides professional and reliable explosion-proof communication technology support for the safe production of petrochemical enterprises.
