System Power Up

The system shows a trouble upon any power-up
because the date and time settings are missing. This
trouble remains until these settings are made.
To reduce the occurrence of false alarms
upon control panel power-up (or restoration
of power after a complete loss of primary and
secondary power), the control panel ignores
all zone faults for approximately 60 seconds
while the devices stabilize.
