I have installed many of these units with no problems what so ever. But the last four units all had the same problem. After connecting the battery as soon as I plug the unit in there is a constant beeping. Everyting preforms like normal but there is this steady tone. Two of the units stopped after two hours and were fine. But the other two would not. APC has no answer but to say we will send you another one. Has anyone had this issue or is it just me.
