Ktt105 Mine Telephones Using The Same Line

KTT105 mine telephones using the same line introduction
KTT105 mine telephones using the same line can be used with the same mine coal mine explosion in one kind of communication equipment intercom call device. Can be two or up to four pairs of links, but also can make communications purposes. This phone from the chassis and handle two parts are made of high quality aluminum material, has good mechanical resistance and moisture corrosion characteristics. The phone "ringer" with moisture performance using a piezoelectric ceramic mounted in the body, all electronics components are mounted on a printed circuit board by means of plugs and sockets and enclosures, battery box located in the body.
