After upgrading to version 5.12.012 or 6.1.222, you may see a message, "Panel Free Memory Low", in Alarm Monitoring.
After upgrading to ReadykeyPRO 5.12.012 or later, with new ISC firmware 3.094 or later, some access panels may display a "Panel Free Memory Low" event.
This is caused by inadequate space reserved for various panel options. This is controlled by the Feature Capacity Level, which controls the amount of memory reserved for downstream devices, timezone control, local linkages, and other features within the controller.
A higher value reserves more room for these options while leaving less room for the cardholder database and event transaction buffer.
In the most cases, the default value of 3 should be left unchanged. This value will rarely need to be adjusted.
If free memory in the panel becomes low, flagged by a "Panel Free Memory Low" alarm, this value should be increased to the value of 4.
Note: Values less than 3 are not recommended. In ReadykeyPRO (6.1.222), the Feature Capacity Level cannot be modified for the LNL-2220 panel.
