All versions of OnGuard
Additional Information
Installed two LNL-1320 Series 3 boards to support two card-in/card-out doors. The first Series 3 board came online with no issues, the second Series 3 board would not come online. Since this was the first time we encountered the issue, we troubleshot the issue thoroughly before finally swapping the second Series 3 board with a Series 2 board. The Series 2 board came online normally. Our review for a root cause pointed to an incompatibility issue with the Series 3 board and OnGuard 7.0 software, even though the Series 3 boards seemed to be intermittently compatible depending on placement within the access control panel.
