FIRECLASS Fire Alarm Control Panels 2 Pseudo Points

2 Pseudo Points
2.1 FIM Pseudo Points
When reported on the user interface or via printers, the
output format used for FIM pseudo points is:
‘Pn’ where n is the point number.
Point
Address
Label Use
1 Data Packet Error The required point command processing could not be completed; the
state of at least one output point was not updated as required.
2 FIFO Full This fault is raised when the panel firmware reaches an internal limit and
is unable to perform an ‘action’ required by the configuration.
The configuration may be too complex for the panel to deal with.
Check the general processing options in the user Causes to see if
multiple Causes in the chain are linked to alarm processing.
3 Not used
4 LNET Data Path Flt The required Network Broadcast of one or more events (state changes)
could not be completed; the state of the network is now unreliable until
it re-synchronises after the successful completion of a 'Fire Reset'.
5 Not used
6 Configuration Store Panel configuration is stored in Flash chips and the data is covered by a
checksum. The panel regularly calculates the checksum and compares
it to that which has been stored. If different, this point is activated. The
panel will also start a shutdown procedure which will result in it restart-
ing and locking into a 'safe state'. It is considered unsafe to use a
configuration that is known to be bad.
7 FIM Comms Failed’ This fault is raised if the SPI channel is held busy by the slave processor
(in this case the FIM Local I/O) for more than a second.
It is cleared when communication resumes.
8–11 ‘Loop A Failed’ to
‘Loop D Failed’
As pseudo point 7 above, but it is used to monitor the loop SPI channels.
This fault is also raised if the slave, loop card is not fitted.
12–24 Not used
25 FIM Bad Packet The main CPU communicates to the FIM local I/O processor, located on
the FIM, using data packets on an SPI link. If three consecutive bad pack-
ets are received as corrupt, this fault is raised.
The fault self-clears after 10 seconds.
26 FIM Fault The FIM Local I/O chip regularly sends a health status about itself to the
main processor. If this status indicates a fault has been detected, this
point is activated.
It is cleared if the health report indicates OK.
The states monitored are the RAM and the firmware checksum.
