FAQs
Why would an "E03 Communication Failure" appear, even if the central station receives a successful report?
Check if the control panel is trying to send a cancel report after an alarm. If the control panel was disarmed within the cancel window time (default is 7 minutes) the control panel will send a cancel report to the central station. If the control panel does not contain the necessary information to send a successful report, this Communication system trouble will appear.
To correct this issue, add an Open/Close Subscriber ID for each Area in use, and add a report code (if not using Point ID). Note: You can disable this feature altogether by setting the cancel window time to zero.
Note: The cancel report signal is enabled if the Dealer answers "Yes" to the question "Enable SIA CP-01?" in the Keypad Easy Menu Programming.
