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, only if using master code. The user/installer code will not clear the LOG.
● 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 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.
8-3-5 Clear Customer Flash Memory
This function will erase all customers configuration (cause-effect programming) stored in panel.
All selective disablements defined on “6-1-3 Set Selective Disablement” will be cleared.
8-4 Other Features
These are programming functions that do not fall into any other category.
8-4-1 Active/Installation Mode
An essential function. The system should always be left in ACTIVE mode, unless the system is being installed and
debugged. When the system is set to Installation Mode the green SYSTEM ON LED on the front panel of the Panel and
Repeaters will flash.
Whilst in Installation Mode the system will automatically detect and record the presence of all connected devices.
To install the system first ensure all detectors, sounders and modules are connected and have power. Next select
Installation Mode using this function, exit programming mode and press SYSTEM RESET.
Once the system has been in Installation Mode for 90 seconds then the system can be put into Active Mode.
Note that there is no clear end to Installation mode because the system is constantly looking and learning. However if the
system is put into Active Mode and Installation Mode hasn’t had time to identify all system components, you will very quickly
be greeted with error reports regarding the presence of unexpected devices.
If devices are ever removed, replaced or added then Installation Mode must be selected so that the system can learn the
new configuration. If you do not do this, the system will report a fault.
8-4-4 Set User Access Code
This function allows the installer to change the customer Access Code. Use ▶

to change code sequence.
8-4-5 Set User Functions
Allows the user access level to be set for every programming function.
Settings are: NONE - READ ONLY - FULL ACCESS
Do not set 8-4-5 Set User Functions to FULL ACCESS or the user will be able to enable all the other functions!
It is not appropriate to set some functions to READ ONLY - for example “8-3-4 Calculate Program Flash Checksum“.
The default setting for all programming functions is NONE.
