Product introduction
The explosion-proof optical fiber waterproof acousto-optic amplifying telephone supports standard SIP protocol and can effectively be compatible with the commonly used IPPBX and network dispatching platform in the market. 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, moisture-proof It has the characteristics of dust prevention, cold prevention, frost resistance, high temperature resistance, oxidation resistance, corrosion resistance, and violence resistance.

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. The handle is made of German Bayer ABS+PC alloy and adopts an integrated evacuation molding structure. Military grade transmitter receiver is selected internally, and permanent magnetic steel is installed. It has the characteristics of explosion-proof, waterproof, moisture-proof, dust-proof, noise resistant, cold resistant, frost resistant, and violence resistant;
3. The hook is made of zinc alloy by stamping. After polishing, electroplating and other surface treatment processes, the back of the hook is sealed with an imported reed pipe, which can be used in conjunction with the built-in permanent magnetic steel of the handle to achieve off hook/on hook switching. The hook has the characteristics of cold resistance, frost resistance, oxidation resistance, corrosion resistance, salt spray resistance, etc;
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 adopts the industrial IP motherboard, and a wealth of signal trunk nodes are reserved to facilitate the linkage with the surrounding 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. The protection grade of loudspeaker and audible and visual alarm light is IP65, and the explosion-proof grade is Exd IIC T6. It is waterproof, explosion-proof, moisture-proof and can be used outdoors;
8. The whole set of the telephone has passed the national explosion-proof grade test, and the explosion-proof grade is ExnA ic IIC T6 G
