KTK18 intrinsically safe amplifying telephone for mining useDetailed product description：

KTK18 intrinsically safe amplifying telephone for mining use
Mainly used for underground drilling and communication areas, when multiple (usually more than 10) loudspeakers are used in combination, to prevent signal attenuation, an additional device is added to amplify the input signal before transmission, expanding the transmission distance.

Main functions of KTK18 intrinsically safe amplifying telephone for mining use

Can communicate with mining intrinsic safety amplifying telephones such as KTK18-D, KTK18-Z, KTK18-ZH, and KTK18 (A) for communication and point-to-point communication;
The amplification phone is equipped with a 4.3-inch LCD screen that can display relevant status information; It can also achieve automatic integration between the dispatch telephone system and the amplification telephone system, which can realize functions such as underground broadcasting, underground finding people, and one click calling. Its main purpose is to solve emergency broadcasting in comprehensive mining and belt tunnels, facilitate finding people, and also serve as an extension and extension of the broadcasting rescue system at the end. At the same time, the amplification telephone in comprehensive mining and belt tunnels can be reused to save costs.
