Intrinsically Safe Expansion Telephone for Mining

Intrinsically Safe Expansion Telephone for Mining

■Overview

Intrinsically safe extension phones are especially suitable for flammable, explosive, high-noise, high-humidity environments such as coal mines, tunnels, chemicals, docks, power plant pipe corridors and other places. The intrinsically safe extension phones are used for dispatching emergency expansion communications and alarms. Communication terminal use. It can effectively solve the communication problems of high ambient noise and high mobility of people in the work area. It has the advantages of easy installation and use, good call quality, and elimination of call blind spots, which can improve work efficiency and ensure on-site production safety.Mine-used intrinsically safe loudspeaker phone is an important part of the centralized control of the working face and belt conveyor protection device. It adopts intrinsically safe design and is easy to install. It has a built-in sealed amplifier to ensure that the signal is not distorted.
