The RSBT includes a number of diagnostics and protection features each of which is signalled through a flashing
sequence on the red LED. After each flashing cycle, there is a delay (OFF time) on the red LED of 1.5 sec before
the next cycle starts. During the alarm recovery period, the red LED will flash at twice the frequency to indicate that
the RSBT is in recovery mode.
