Hey to all,
I installed a new Fireworx FX-64RD panel a couple of months ago. Almost from day one started to receive sporadic Telco Line Faults. Both Line 1 and Line 2. Little correlation can be determined except it happens 9 times out of 10 during the week Monday - Friday and during the day 9am to 5 pm. In other words 90% of the time during working hours. (aka when the phone are likely to be used)
It happens 1 to 3 times in a given day and then skip a day or two.
It was originally connected to their Line 1 and Fax Line, I have moved to L-1 and L-3 no help. It is now on L-1 and L-2 and am waiting to see how it goes. Line 1 happens less frequent so I have left it alone.
In calling UTC Tech Support........................... I was told that the threshold voltage is 10vdc.
I have gotten the 10vdc from a couple of different techs so that must be the number but it seems to be on high side. I remember on a burg panel that I was having a problem a couple of years ago I was told the threshold was6vdc.
What I am reading at the panel is 6.5 to 7.5vdc when a phone is off hook. So if the threshold is 10vdc then the panel is going to go into trouble after the timeout of 2 minutes which is the maximum.
The lines that I am working with are (what I think is) POTS lines on copper. However I was told that if there is a digital converter?? it could cause some trouble. How do I determine if this is the case???
Has anyone here experienced this?? Especially on this panel??
Any additional thoughts that may help would be appreciated.
