The UPS status and any anomalies are reported by a buzzer, which emits a modulated sound according to the various UPS operating
conditions.
The different types of sound are described below:
Sound A:
This sound is emitted to confirm any touch screen command.
Sound B:
This sound is emitted when the UPS switches to bypass.
Sound C:
This sound is emitted when the UPS switches to battery status.
(When the battery end-of-
discharge signal is given the buzzer sound change to pattern “D”).
Sound D:
This sound is emitted when a generic alarm occurs (lock, fault, anomaly, warning).
Sound E:
This sound is emitted when there is an inverter lock or load off alarm.
Sound F:
This sound is emitted if a battery overvoltage fault occurs.
Sound G:
This sound is emitted in case of a battery test fault. The buzzer emits ten beeps.
The alarm signal indicates the necessity to replace the battery or to perform a service on the UPS.
When an alarm is silenced, all the alarms with same sound are silenced, the buzzer is reactivated when an alarm with a different
sound pattern appears.
