No host amplification intercom system

SH-8000 (K) Host less Loudspeaker Intercom System
The SH-8000 (K) intelligent host less loudspeaker intercom system is an internal communication system with broadcasting and intercom functions developed based on the characteristics of industrial enterprise production environment and internal communication. The company provides auxiliary functional units such as voice alarm control devices, telephone access control devices, partition merging and separation control devices, voice recording devices, and dedicated optical end equipment that supports fiber optic transmission. The company can also provide users with comprehensive value-added solutions according to their individual needs.
The SH-8000 (K) intelligent host less loudspeaker intercom system is widely used in industries such as petrochemicals, drilling platforms, power plants, metallurgy, mining, building materials, coal preparation plants, ports, pharmaceuticals, civil explosives, papermaking, water treatment, and military.

Features
■ Well functioning: The system has functions such as call intercom, emergency broadcasting, linked control voice alarm, program-controlled telephone access, and merging and separating control of broadcasting areas;
■ High driving power: Each speaker station has a amplification power of up to 50W, which can directly drive multiple speakers to work simultaneously without the need for additional auxiliary amplifiers; The telephone line design has a sleep function, which enters the working state when driven by external signals. In standby mode, the power supply of the telephone station automatically exits, improving the service life of the equipment;
High explosion-proof level: The highest explosion-proof level of on-site terminal explosion-proof equipment is IICT6;
Good protective performance: The wall mounted telephone station adopts an integrated design, with a reasonable structure and beautiful appearance. The shell is injection molded from reinforced ABS engineering plastic, the hook switch adopts magnetic induction technology, and the explosion-proof phone adopts a built-in explosion-proof chamber. The whole machine has good protection and anti-corrosion performance, strong impact resistance, and the highest protection level is IP66. Suitable for harsh environments such as humidity, dust, corrosion, and gas explosion hazards;
■ Unique anti noise effect: The dynamic coil microphone adopts a special oblique angle design, combined with a unique background noise elimination circuit, which can effectively eliminate background noise, making it suitable for use in 115dB strong noise environments, and clear amplification and intercom;
■ Easy to use: The handle is equipped with a call button, which allows for easy one handed calling/communication;
System stability and reliability: Each substation has an independent power supply and amplifier, and the system adopts a bus parallel hanging connection method, without the need for a host connection. Any substation failure will not affect the normal operation of the system; At the same time, users can freely expand and migrate call station terminals;
Long transmission distance: The system is equipped with a dedicated optical transceiver that supports fiber optic digital transmission, with a transmission distance of 20 kilometers.
Easy installation and maintenance: The system equipment is designed reasonably, making it convenient for installation, wiring, and equipment maintenance.
