On a site with a Napco P1632 the customer complained of being constantly disconnected. The CS history all looks normal. The only abnormal was the panel reporting a restore when the phone service tech reconnected the phone line to the house. The panel reported a phone line restoral... of course the phone tech happened to have his butt set hooked up and claimed that was a guaranteed demonstration that the panel was causing the problem.
I don't see anything wrong. Is it possible that the panel is seizing the line and then releasing it without calling out for no reason? Just want to be sure. I suppose if it had been mis-programmed it could do that, but not continuously every day, and not as a recent symptom.
Its in an outer suburb area that I think is running over a small carrier system. I suppose the phone company might not be providing full voltage at all times, but then the panel should report when the voltage comes up. Not seize the line and then drop it without reporting. Seems weird to me.
Sounds like a telco problem and they are just trying to blame the alarmco, but if anybody can think of a possible cause I would sure like to check it out.
Of course the phone company guy told the customer he is an expert on alarm systems.
