CORE Board Faults
When there are no faults in the fire system, the LED light will stay solid. When there is a fault, the LED light
will flash with a short break. Count the flashes then wait for the short break to determine the fault.
NOTE: CORE Boards with software version 1.68 and prior will use one brief flash every 3-seconds
to indicate there are no faults in the fire system.
