Hello my friends, In this video we are going to a building for service and they removed the door panel because it was broken, they said the switchboard is broken, this place cannot be done and left it. First of all, we removed the Audio's talking system switchboard, replaced it with a zero and changed it to make the system work. Since the cables, switchboard and the junction box were in a bad condition, we had to change the DT8 cable. Later, we found that the cables going to the door automatic were added too much and we renewed that cable as well. We tested the new double row talking door button we brought, the cables coming from the apartments one by one and made the numbers, door bell and door numbers equal to each other. We delivered the apartment bells, talking system after testing them. When we tried to connect the old switchboard back to the system, we observed that it worked in the old talking switchboard. I hope it will be useful and you like it, Thank you, I wish you a good time... Join this channel to benefit from the privileges: / @elektrikveelektronikdersleri
