3. Component (all LEDs off if no alarm exists)
The card will iterate through the list of active alarms showing only
one of the active alarms at a time. A System Controller with two
alarms, for example, would flash the following sequence on the LEDs:
Status - alarm code 1 - alarming component 1 - Status - alarm code 2 -
alarming component 2 - Status - alarm code 1 - alarming component 1
etc.
