Table 4; Alarm Conditions - Orion Power Systems SCR2 User Manual

Under fault conditions, the Fault indicators will be illuminated indefinitely while the battery charger
is operational, or for a maximum of 5 minutes while the battery charger is not operational.
If a problem persists, consult your local distributor, Sales representative or contact the
Technical Support Group. Please have the UPS model number and serial number
available at the time of your inquiry.
All audible alarms can be silenced, with the exception of Low Battery, Bypass Reminder and Missing
Batteries at Startup alarms. Once silenced, the alarm will not sound again until a new alarm
