I am not sure what you mean by battery switch beeping. Our only battery switch in our Greyhawk is the battery disconnect by the entry door, and it does not have any type of beeper alarm. Now in that same area of the house are several alarms that do have beepers, e.g. CO/LP detector, Bigfoot leveler control and the inverter. Could one of those be beeping?
