LPA LED Status Combinations
LPA Module LED
Each LPA module is provided with a bi–color LED on the ETIB module
next to the MMI connector. Interpret this LED as follows:
S GREEN — LPA module is active and is reporting no alarms (Normal
condition).
S Flashing GREEN/RED — LPA module is active but is reporting an
low input power condition. If no BBX is keyed, this is normal and
does not constitute a failure.
S Flashing RED — LPA is in alarm.
