We have found that in Solution 6000 Firmware V2.53.73 that the RF Supervision time at Menu 621 is set to only 1 Hr and not 24Hrs as in previous firmware's.
This can also be found and changed in Solutionlink.
This is on the DEVICES Tab
Under RF Devices
Supervision Time
Select DETAIL view.
Should you see issues with RF Device Supervision fail or other issues similar we would suggest to check this programming and CHANGE to the 24Hr Supervision time and then test panel operation.
Having RF Supervision set to 24 Hr. should avoid any issues due to transient RF reception on site.
