HI! I have a new customer , asking for quote Tel/Paging not working ,,, I found 3 Horns 10-15watt,, 1- horn is connected by underground cable to a building 120 ft away ,, now the cable is on a normal 25 pair indoor cable , which goes into a conduit , so it has no ground sheath ,, the main problem is the 65 watt amp is fried , , i have put protection on telephone circuits ,, but what to u normally use for paging outputs to go underground ,, its 70Volt out put , i doubt they will replace the cable ,, the Digital nortel phone is working fine on the same cable. Thks
