There are three main memory sections on the panel. In the following table most important info is shown:
CUSTOMER FLASH
“System Cause-Effect and Config”
NVRAM
“local memory”
“ONLINE” DATA
(cleared upon reset)
access codes
mem. checksums
Device Analog Value per Loop
global config
delays activation
Device Type Value per loop
specific device config
dev. disable
Fault activation
sounders groups config
zone disable
Fire activation
ios groups config

These memory settings are not erased upon Clear NVRAM.
8-3-1 Checksums
This function displays the current calculated checksum between processor and Non-Volatile-Ram.
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:
●
The Analogue Loop will be enabled
●
All disabled Zones will be enabled
●
All disabled devices will be enabled
●
All disabled sounders will be enabled
●
The event log will be cleared.
●
The auto-reset count will be cleared
●
Information on fitted devices and their types will be cleared
●
All checksums will be cleared and recalculated
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.
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 are downloaded automatically resulting 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.
8-3-5 Clear Customer Flash Memory
This function will erase all customer configuration (cause-effect programming) stored in the panel.
All selective disablements defined on “
6-1-3 Set Selective Disablement”
will be cleared.
