DIA and both the printer and CRT. A DUART failure can be caused by a static
discharge that momentarily confuses and locks up the DUART.
Corrective Action:
1) Remove power from the AM2020/AFP1010, batteries first and then AC. Wait
one minute. Reapply power - AC first, then batteries.
2) Check programming. Has the AUX printer been enabled? If yes, is the AUX
printer connected properly? If no AUX printer exists, go into programming
and disable it. Cycle power and trouble will clear.
3) If the trouble does not clear, call Notifier Technical Support.
This error is caused replacing the software in the panel with an older revision
that does not support some of the features programmed.
initially started up with revision 6.5 software and is programmed using some of the
security features, such as: the SDEL Type I. D. (Security Delay). Then, for some reason
the software is replaced with an older version, such as release 5.0 which did not support
security. When the panel starts up, it will not recognize the SDEL Type I. D., so the TD2
Trouble Code will be generated.
Corrective Action:
1) Either reprogram the panel using valid Type I. D.s and Control By Event
Equations or upgrade the operating software to a newer combination that
supports these features.
The AM2020/AFP1010 has detected an error condition on the printer.
Corrective Action:
1) Verify that the printer is "on-line."
2) Verify that the printer has paper and it is not jammed.
3) Make sure the EIA-232 is plugged into the correct port on the printer.
4) Verify the wiring between the Serial Interface Board and the DB-25 connector.
This Trouble Code applies to the AUX printer. The AUX printer is an 40-column
strip printer that is designed to be mounted inside the FACP cabinet. This
trouble condition will occur if the AUX printer is mistakenly programmed into the
system when it is not actually present in the system. If an external serial printer
(PRN) is being used in the system, do not enable the AUX printer in Full or
Partial System Programming. See trouble code TD1, Catastrophic DUART.
Corrective Action:
1) Check the programming of the AUX printer in Full or Partial System Program
ming.
When there is a problem with one of the printers (PRN or AUX) such as the
printer has been taken off-line or is out of paper, the AM2020/AFP1010 will try to
maintain all the messages that are being sent to that printer (in the Internal Print
Buffer) so they won't be lost. However, the buffer can only hold fifty messages. If
more than fifty messages are sent to the buffer it will overflow and the Trouble
Code will be generated.
