Issue
CMD40 System Trouble Report Codes Display - COMMAND 40
Solution
Keying COMMAND - 4 - 0 at the Command Center will replace the display of zone status on the four left indicator lights with a trouble report code. If applicable, a second trouble report can be displayed by keying in another COMMAND 40 (the maximum number of troubles held in the buffer is two). If no indicators light on the second COMMAND 40 entry, there is only one cause for each trouble report.
After the panel is disabled/restarted, powered cycled, or serviced for the indicated system troubles, clear the system trouble memory by entering COMMAND 40 until no troubles are displayed. Press any key to exit COMMAND 40 since it is not automatically exited upon alarm or trouble condition. Alarms and troubles will continute to report to the central station unabated.
