4.2 List of System Faults – Non-Networked
The complete list of faults which can be displayed by a system fault recall is as follows:
1. Mains fail
When mains fail appears in a system fault recall it indicates that mains is currently
failed. When mains have failed continuously for 8 hours a system fault may be
generated depending on programming.
2. EEPROM database checksum error
The panel is in-operational if this fault is present.
3. EEPROM database version error
This fault condition means that the EEPROM database checksum is correct but the
database is an old version with a format which cannot be used. All circuit processing
is disabled when this fault is present and the panel is in-operational.
4. Module configuration mismatch
This fault occurs when the number of Zone or Relay Modules installed does not
match the programmed number of modules required to be present. The bottom line
states processing is enabled or disabled. On detection of a module mismatch
processing is disabled and the panel is not operational. A technician can temporarily
assign a new configuration so that processing can be re-enabled and use only those
modules that are present. This System fault will remain until the correct number of
modules is installed and verified as operating correctly.
5. Keypad disconnected
Processing of circuit inputs and alarms continues.
6. LED display board fault
There is a fault with a zone or relay LED display board. This can occur if the wrong
number of display boards is installed.
7. LCD display fault
A fault has occurred with the 80 character LCD. This can occur at startup or during
an LCD test.
8. EPROM CRC error
A checksum calculation of EPROM memory has failed. This can occur during
System and Auto Test.
9. RAM write read fault
A write read test of main RAM has failed. This can occur during System and Auto
Test.
