Alarm Description
1 Power PSU Critical PSU1 in the cabinet does not work properly. A sum
signal from the PSU1 indicates that at least one volt-
age output has dropped. If no mains breakdown relay
is used, then the alarm will also be sent at mains
breakdown.
Ceasing PSU1 in the cabinet works properly again. Ceasing is
sent if the PSU1 works at start-up, and there is a cor-
responding critical PSU1 alarm logged in the Events
log. The repeater will restart when the power is back
and this alarm will be sent.
