HI!, I wondering if a CIRCA QC2 6pair protector would work for protecting 1 Paging Horn 10w connected by underground cable . to main Blding , 60 amp bogen 70v, the original setup has no protection , i found fried amp ,, so i was thinking it was hit by lightning ,,surge or ?? So i have this Circa 600QC2 , i also would be connecting a Nortel digital extention. Thks

No. I use a one specifically for this from DITEK for outside 70v audio. But unfortunately the site seems to be down at the moment. I'll give it a try later and tell you which.

And to be honest with you the 70v line needs to be a separate cable (just in case you were planning on putting it on a pair in the same cable with the phone).

The Circa can be used for the digital extension if you use a suitable 5 pin protector.

Ahh, working now. Looks like the DTK-1LVLPSCPRUV is the one.
