Product Description

KNFH Series Of Audio Signal Lightning Protection Gate 

 

KNFH series of audio signal lightning protection gate is mainly used for network system of public 

telephone network signal transmission, such as telephone, fax machine, MODEN, switch, ADSL, ISDN 

and other equipment lightning and overvoltage protection.

Installation And Maintenance

1.This product series in the protected equipment signal circuit, and close to the protected equipment.

2.The input(IN) and output(OUT) cannot be reversed; the input(IN) is the lightning intruding end, output   

   (OUT) is connected with the protection device.

3.For the normal work of SPD, grounding is very important, the grounding wire cross-sectional area is

   no less than 4m square meters, and as short as possible.

4.Lightning protection gate without special maintenance, but it's long-

   term energized, so need messenger to inspect regularly, especially in the thunderstorm season, after the 

   lightning strike, it should be inspected on time, if found that the loop signal is abnormal, removing 

   protection gate, loop signal will back to normal, it means Lightning protection gate has been damaged or 

   life has ended, replace the new lightning protection gate on time.

5.The outside length of Coaxial line more than 30m,it should be in the coaxial two ends with lightning 

   protection gate to ensure the better lightning protection effect.
