POWERING UP THE PANEL cont.

AUTO START

The panel contains a "watch-dog" timer. Should there be a major disturbance to the hardware

(e.g., electrical storm, static, etc.), this timer will reset and force the panel to effect an AUTO

START. A flashing alert message will appear that must be acknowledged (see page 40).

P.CODE START

As the panel is executing its instructions from the main program EPROM, it will check the

EPROM checksum against a stored value. If it detects a difference, it will restart the program

and indicate this by displaying P. CODE START. An alert message will appear that must be

acknowledged (see page 40). This situation is very rare.

PROGRAM SELF-TESTS

During the start-up routine, the panel will perform several comprehensive self-tests and display a

fault warning message if any test fails. The display will show RAM FILE ERROR and the

piezo-sounder will beep. Press the RETURN key to acknowledge the condition and then

continue on. For the sake of clarity and because such failures are rare, these tests have not been

included in the previous discussion.

The self-checks performed are for RAM function and a RAM data checksum. The flashing

warnings displayed are:

RAM FAIL AT nnnn - indicates a memory-component fault. The printed circuit board has to be

replaced.

LOG DATA LOSS! - indicates that some or all of the log data is corrupted. If the log is printed

or displayed, then certain entries may yield garbage displays. The dates and/or times of logged

events may also be corrupted. The log error message is cleared when acknowledged and no

further action is required.

LIT DATA LOSS! - indicates corruption of some or all of the system literals. The panel will

check all 750 literals in the program and any that are corrupted will be defaulted back to their

factory settings. The defaulted literals are displayed and printed. If the panel can complete this

routine, print a copy of the system literals (see page 53) and compare it with an old record.

Depending on the severity of the corruption, a recovery may not be possible and a COLD

START with ZAP will have to be performed (see page 35).

IDS/OPTIONS ERROR - indicates corruption of the user identification codes or options. The

panel may default all identification codes and options to their factory settings. All user

identification codes and options may need to be reprogrammed.
