Product introduction
The explosion-proof optical fiber hands-free waterproof acousto-optic loudspeaker telephone supports the standard SIP protocol and can effectively be compatible with the commonly used IPPBX in the market and the network dispatching platform. It is a special telephone specially developed for high humidity and high dust environments such as subway tunnels, underground pipe gallery tunnels, highway tunnels, mines, power plants, power plants, steel plants, ports, ships, and electrolysis workshops. It is suitable for long-term installation in various harsh environments and is waterproof It is moisture-proof, dust-proof, cold proof, frost resistant, high temperature resistant, oxidation resistant, corrosion resistant, and violence resistant.

Product features
1. Aluminum alloy material, formed by more than 1000 tons of die-casting machine, has high density, light weight, and is characterized by cold and frost resistance, oxidation resistance, corrosion resistance, and resistance to violent impact;
2. Hands free design, the button is made of 304 stainless steel, with blue light indicator light, and one key speed dial button is set;
3. The speakers shall be high-quality industrial speakers, and the back of the external speaker holes shall be equipped with anti piercing stainless steel mesh, which can effectively protect the speakers from damage;
4. The keys are made of anti-aging silicone material, professionally designed to be waterproof and dust-proof, and matched with gold plated PCB board. They have good hand feel, good electrical performance, and a service life of ≥ 500000 times;
5. The telephone motherboard is developed by using imported single chip computers and the chips grinded by the company. All components are SMT chip mountings, which have rich functions and high integration. Two dry node interfaces are reserved for one off and one off to enhance the linkage with external equipment;
6. The phone shell adopts multiple waterproof design, all incoming lines are sealed with professional anti-aging waterproof electronic glue, and the overall protection level of the phone reaches IP68;
7. As required, the ring can be moved outside the shell to solve the problem that the ring tone of similar products in the market is too small, which causes that the ring tone cannot be heard when being called.
