Overview:

This explosion-proof digital intercom control box has intrinsic safety and explosion-proof performance requirements, and meets the requirements for hazardous areas in Zone 1 and Zone 2 of explosive gas environments. It can be applied to fields such as petrochemicals, coal mines, metallurgy, energy, transportation, etc.

Adopting stainless steel material as the panel and shell design, the overall appearance is treated with electrophoretic technology, which is wear-resistant and beautiful. The panel design has 7 quick call buttons, which can complete call and intercom with one click. The buttons are designed with backlight indicators, which can also be clearly recognized at night or in dim light. The voice acquisition gooseneck microphone uses imported marking modules, metal bendable connecting rods, clear sound quality, long pickup distance, and has radio frequency interference shielding technology, which can effectively resist external interference.

One click quick establishment of hands-free communication between both parties, allowing either party to hang up and talk back. With excellent noise suppression function, it can learn noise environment independently in noisy environments and filter it out. Only the voice of the caller can be heard, but environmental noise cannot be heard.

Featuring integration, high reliability, and high protection level.

The telephone has functions such as explosion-proof, dustproof, and anti-corrosion, meeting the requirements of the national standard GB/T15279-94 for telephones.
