FUNCTIONALITY
8-3-2 Clear Non-Volatile RAM
Clearing the NVRAM clears all the installation settings and the system is automatically put into Installation
Mode.
On the Panel this will result in:
After clearing the NVRAM it is essential to perform a system Master Reset.
8-3-3 Calculate Customer Flash Checksum
Calculates and stores the checksum for all the data in the customer Flash memory.
When settings are changed using the programming functions this checksum will be re-calculated as
required. Downloads of customer data also result in an automatic update of the checksum. However if a
SIM CARD is supplied with pre-programmed data (i.e the data changed externally) this function is
necessary otherwise the panel will believe the data has been corrupted and report a fault.
This stored checksum is regularly (approximately every 2 minutes) compared with a freshly calculated
checksum to check for memory corruption.
8-3-4 Calculate Program Flash Checksum
Unlikely to be required in normal circumstances, this function calculates and stores a checksum for the
program Flash memory.
Software upgrades, either downloaded, or from a new SIM CARD are detected by the Panel and
automatically result in a new checksum being calculated and stored.
This stored checksum is regularly (approximately every minute) compared with a freshly calculated
checksum to check for memory corruption.
