DSC 1832/RFK5500 w 2 wireless sensors.
Have been OK for the last 6 months, then both indicated Default.
I called tech support, removed the sensor batteries and after quite awhile of trying various settings, he talked me through resetting about everything.
They were OK, then around 24 hours later I heard a beep, they went back into default.
I had recently brought the XMAS tree down from the attic and am wondering if I could have bumped a wire.
Any ideas would be appreciated.
